Description

  The present invention relates to a measurement result display device and a measurement result display method for displaying a measurement result display frame for displaying measured levels of a plurality of measurement target components by a graph.

  As a measurement result display device that displays a frequency spectrum in accordance with this type of measurement result display method, a frequency spectrum analyzer (hereinafter also simply referred to as “analyzer”) is disclosed in Japanese Patent Laid-Open No. 2005-214777. This analyzer employs a configuration in which an analog signal to be analyzed is converted into digital data, a power spectrum is obtained by a predetermined calculation process, and a spectrum waveform indicating the result is displayed on a display unit. In this case, in this analyzer, as an example, the frequency in the spectrum obtained by the arithmetic processing is made to correspond to the horizontal direction of the screen and the level for each frequency is made to correspond to the vertical direction of the screen, and the peak power (measured) is measured for each frequency. Level) is displayed as a spectrum waveform.

Japanese Patent Laying-Open No. 2005-214777 (page 4-7, FIG. 3-5)

  However, the conventional analyzer has the following problems. That is, the conventional analyzer employs a configuration in which a spectrum waveform is displayed in which the frequency is associated with the horizontal direction of the screen and the level for each frequency is associated with the vertical direction of the screen. In this case, as a usage pattern of this type of apparatus, there is a usage pattern in which a change in level according to time for each frequency is analyzed. With respect to such a usage pattern, a conventional analyzer can obtain a spectrum for each time by shifting the time window during the above-described arithmetic processing. However, in the conventional analyzer, when trying to analyze a change in level according to time for each frequency, it is necessary to sequentially switch and display the spectrum waveform for each time. For this reason, in the conventional analyzer, not only the switching operation of the display screen is complicated, but the spectrum waveform corresponding to the time before and after the measurement time of the displayed spectrum waveform is not simultaneously displayed on the display screen. For this reason, it is difficult to intuitively grasp the level change amount.

  In order to improve such problems, the applicant measures the frequency spectrum of the input signal at predetermined time intervals, and displays a graph representing each measured spectrum by shifting it by a predetermined amount in the display screen and displaying it in the order of measurement. We are developing a measurement result display device. Specifically, in the measurement result display device developed by the applicant, as shown in FIG. 6, the frequency (in this example, 10 kHz to 40 kHz) corresponds to the horizontal direction of the screen (the direction of the arrow A1) and the frequency. Spectrum display frames 11a to 11h (hereinafter referred to as graphs) for displaying the measured levels for each frequency in correspondence with the vertical direction of the screen (in the direction of arrow A2) with respect to the level (in this example, -130 dB to -30 dB). , Which is simply referred to as “frames 11a to 11h”, is shifted in the diagonally lower left direction (in the direction of arrow A3) intersecting arrows A1 and A2, and can be displayed in a measurement result display screen 10x. It is configured. According to the measurement result display device developed by the applicant, the frames 11a to 11h (hereinafter, also referred to as “frame 11” when not distinguished) displayed in the order of measurement without performing a complicated switching operation. Each graph Ga-Gh can be referred to.

  In this case, in the measurement result display screen 10x of the measurement result display device developed by the applicant, in the foremost frame 11a, the grid display 12 and characters indicating the relationship between the frequency and level and each coordinate in the frame 11a. Since there is information (in this example, character information of “10 kHz”, “20 kHz”, “30 kHz”, “40 kHz”, “−130 dB”, and “−30 dB”), the graph Ga of this frame 11a is referred to. In this case, it is possible to intuitively recognize which frequency is at which level. However, in the frames 11b to 11h, not only the grid display 12 and the character information do not exist, but also the upper frame 11 is shifted to the upper right, so that the graphs Gb to Gh are displayed for the unfamiliar user. When referring, it is difficult to intuitively recognize which frequency is at which level. For this reason, it is preferable to improve this point.

  On the other hand, by designating any one of the frames 11a to 11h, the applicant separately displays the graph G of the designated frame 11 together with the grid display on the display screen separately from the frames 11a to 11h. A measurement result display device configured to display on the display part has been developed (not shown). According to this measurement result display device, as described above, the desired frame 11 is also selected for the frames 11b to 11h (graphs Gb to Gh) that are difficult to intuitively recognize which frequency is at which level. It is possible to easily read the graph G of the frame 11 simply by specifying. However, even if such a configuration is adopted, it is still necessary to refer to the frames 11a to 11h (graphs Ga to Gh) displayed in an overlapping manner in order of measurement in order to grasp the amount of change in level for each measurement time. Therefore, it is necessary to move the line of sight when alternately referring to the graphs Ga to Gh of the frames 11a to 11h displayed overlapping in the measurement order and the graphs displayed separately from these. For this reason, it is still difficult for an unfamiliar user to read the frequency and level.

  Hereinafter, embodiments of a measurement result display device and a measurement result display method will be described with reference to the accompanying drawings.

  A measurement result display device 1 shown in FIG. 1 is a spectrum analyzer that measures and displays a frequency spectrum of an input signal Si, and includes a measurement unit 2, a memory 3, an operation unit 4, a display unit 5, and a control unit 6. Configured. The measuring unit 2 includes an amplifier that amplifies the input signal Si, an A / D converter (not shown) that digitally converts the signal amplified by the amplifier, and the like. The measurement data D1 is generated and output by sampling in step (1). The memory 3 stores the measurement data D1 and the calculation result of the control unit 6 (measurement data D2, which will be described later). In this case, as an example, the memory 3 defines a plurality of storage areas in a ring buffer format for storing the measurement data D1 sequentially output from the measurement unit 2 by the first-in first-out method.

  The operation unit 4 includes various operation switches for setting operating conditions of the measurement result display device 1 and a plurality of spectrum display frames 11a to 11h ("measurement result display frames" shown in FIG. In the following, the frame 11 is simply referred to as “frames 11a to 11h.” When not distinguished from each other, the frame 11 is designated, or the scale display 13 and the cursor display 14 ( 2) and an operation signal S1 corresponding to the switch operation is output to the control unit 6. The display unit 5 includes a color liquid crystal display panel, and displays the measurement result display screen 10 shown in FIG. 2 and the like under the control of the control unit 6.

  For example, the control unit 6 includes an FPGA (Field Programmable Gate Array) and a CPU. The control unit 6 sequentially stores the measurement data D1 output from the measurement unit 2 in the memory 3 and a predetermined value for the stored measurement data D1. By executing the calculation process (for example, fast Fourier transform, etc.), the frequency spectrum of the input signal Si at every predetermined time is calculated to generate the measurement data D2. Further, the control unit 6 causes the display unit 5 to display a measurement result display screen 10 (see FIG. 2) based on the measurement data D2.

  In this case, the measurement result display screen 10 is a display screen for displaying the frequency spectrum calculated by the control unit 6 in the order of measurement. As shown in FIG. 2, the measurement result display developed by the applicant is shown. In the same manner as the measurement result display screen 10x in the apparatus, a plurality of frames 11 are displayed overlapping each other with a predetermined amount shifted. In the figure, only eight frames 11a to 11h are illustrated in order to facilitate understanding of the screen configuration of the measurement result display screen 10, but in the measurement result display device 1, the user It is possible to display a larger number of frames 11 (for example, 10 to 200 frames) in the measurement result display screen 10 according to the purpose.

  In this measurement result display device 1, the frequency (an example of “component to be measured”: 10 kHz to 40 kHz in this example) corresponds to the horizontal direction of the screen (direction of arrow A 1: an example of “first direction”), and the level. (Measurement level (frequency spectrum)) for each frequency in correspondence with (size: “dB”) in the vertical direction of the screen (direction of arrow A2: an example of “second direction intersecting the first direction”) Is displayed in the measurement result display screen 10 by graphs Ga to Gh (hereinafter also referred to as “graph G” when not distinguished). Further, in this measurement result display device 1, each frame 11 is shifted to the lower left direction (direction of arrow A3: an example of “third direction”) and overlapped in the order of measurement (as an example, a measurement result close to the latest measurement result). The measurement result display screen 10 is displayed so as to be displayed in a three-dimensional manner (overlapping in the direction from the upper right to the lower left so that the frame 11 is located at the lower left. It is also possible to adopt a configuration in which each frame 11 is displayed in the reverse order of the measurement order in the direction from the lower left to the upper right so that the frame 11 of the measurement result closer to the latest measurement result is located at the upper right.

  Further, in the measurement result display device 1, for reading a numerical value of the graph G of the designated frame 11 among the frames 11 (the graph Ga of the foremost frame 11 a in the measurement result display screen 10 shown in FIG. 2). The grid display 12 is displayed so as to overlap the designated frame 11. In this case, the grid display 12 has the same type of shape as the frame 11 for displaying the graph G, and the size thereof is the same as that of the frame 11. Therefore, for example, when the frame 11a is designated, the grid display 12 is displayed so as to overlap the frame 11a so that the outer edge of the designated frame 11a and the outer edge of the grid display 12 overlap. In this case, in the measurement result display device 1, as described later, when another frame 11 is designated, the grid display 12 is moved and displayed so as to overlap the newly designated frame 11. Is adopted.

  Further, in the measurement result display device 1, character information indicating the relationship between the frequency and level and each coordinate in the frame 11 (in this example, “10 kHz”, “20 kHz”, “30 kHz”, “40 kHz”, “−” The character information of “130 dB” and “−30 dB”) is associated with the grid display 12 and displayed around the specified frame 11. Further, the measurement result display device 1 employs a configuration in which a scale display 13 and a cursor display 14 for designating a desired frequency in the “designated frame 11” are displayed on the frame 11 in an overlapping manner. Yes.

  In this case, in the measurement result display device 1, a desired frequency (an example of “measurement target component”) is obtained by moving the scale display 13 in the horizontal direction (first direction) of the screen in the “designated frame 11”. Can be specified. Further, in this measurement result display device 1, the cursor display 14 is moved and displayed at the intersection of the graph G displayed on the designated frame 11 and the scale display 13 with the movement of the scale display 13. The configuration is adopted. Further, in the measurement result display device 1, the frequency and level corresponding to the coordinates of the cursor display 14 in the “designated frame 11” (the frequency designated by the scale display 13 in the designated frame 11 and designated). The measurement value display 15 (see FIG. 3) indicating the level designated by the cursor display 14 in the graph G of the frame 11 is displayed so as to overlap the “designated frame 11”.

  When using the measurement result display device 1, first, the operation unit 4 is operated to set the operating condition (measurement condition) of the measurement result display device 1. Specifically, as an example, the spectrum of each frequency within the range of 10 kHz to 40 kHz for the input signal Si is measured, and the measurement result (in this example, any one of the range within the range of −130 dB to −30 dB) Is set to be displayed on each frame 11 by the graph G. In this case, as an example, the drawing interval of each frame 11 (measurement time interval of each frame 11 corresponding to the “third direction”) is set to 1 second (1 s). Next, by operating the start switch of the operation unit 4, the frequency spectrum display process (display process of the measurement result display screen 10) by the control unit 6 is started.

  Specifically, when an operation signal S1 instructing the start of processing is output from the operation unit 4, the control unit 6 controls the measurement unit 2 to start measurement processing. In response to this, the measurement unit 2 digitally converts the input signal Si, samples the converted digital signal at intervals of 1 second to generate measurement data D1, and outputs the generated measurement data D1 to the control unit 6. . Further, the control unit 6 sequentially stores the measurement data D1 output from the measurement unit 2 in the memory 3. Further, the control unit 6 executes a frequency spectrum calculation process based on the measurement data D1 in parallel with the storage process of the measurement data D1 in the memory 3. Specifically, the control unit 6 calculates the frequency spectrum based on the measurement data D1 by reading the measurement data D1 stored in the memory 3 and executing a predetermined calculation process (such as fast Fourier transform). Measurement data D2 is generated, and the generated measurement data D2 is stored in the memory 3. In addition, since the calculation method of the frequency spectrum based on the measurement data D1 digitally converted by the measurement unit 2 is publicly known, detailed description thereof is omitted.

  Further, in parallel with the series of processes described above, the control unit 6 generates display data for displaying the calculation result (measurement result: frequency spectrum for the input signal Si to be measured) and outputs the display unit 5 output. As a result, the measurement result display screen 10 is displayed on the display unit 5. Specifically, the control unit 6 first generates display data for displaying the frequency spectrum based on the first measurement data D2 as the graph Ga on the frame 11a and outputs the display data to the display unit 5. In this case, when the display data generated based on the first measurement data D2 is output to the display unit 5, only the frame 11a (graph Ga) is displayed in the measurement result display screen 10, and the grid is displayed. The display 12 is displayed so as to overlap the frame 11a, and the frames 11b to 11c are not displayed (not shown).

  Further, when displaying the frequency spectrum based on the second measurement data D2 (measurement data D2 generated one second after the first measurement data D2), the control unit 6 displays the first one displayed on the frame 11a. The graph Ga based on the measurement data D2 is displayed on the frame 11b as the graph Gb, and the frequency spectrum based on the second measurement data D2 is displayed on the frame 11a as the graph Ga. Thus, two frames 11a and 11b (graphs Ga and Gb) are displayed in the measurement result display screen 10 (not shown). Further, when displaying the frequency spectrum based on the third measurement data D2, the control unit 6 displays the graph Gb based on the first measurement data D2 displayed on the frame 11b as the graph Gc on the frame 11c. In addition, the graph Ga based on the second measurement data D2 displayed on the frame 11a is displayed on the frame 11b as the graph Gb, and the frequency spectrum based on the third measurement data D2 is displayed on the frame 11a as the graph Ga. As a result, three frames 11a to 11c (graphs Ga to Gc) are displayed in the measurement result display screen 10 (not shown).

  In this case, in the measurement result display device 1, in the display process of the measurement result display screen 10 executed in parallel with the series of measurement processes, as an example, the grid display 12 is displayed so as to be superimposed on the foremost frame 11 a. (A configuration example in which the foremost frame 11a in the display process executed in parallel with the measurement process is set as the “designated measurement result display frame”) is employed. In the measurement result display device 1, the graph G (in this example, the graph Ga of the frame 11 a) of the frame 11 (designated measurement result display frame) for displaying the grid display 12 in an overlapping manner is displayed on the other frames 11. A configuration is adopted in which the graph G is displayed in a distinguishable manner. Specifically, as an example, the display color of the graph Ga of the frame 11a on which the grid display 12 is superimposed is blue, and the display color of the graph G of the other frame 11 is red (“graph display color”). (Example of a configuration in which the display mode is different depending on the difference in (line color)). In FIGS. 2 to 3, the difference in display color of each graph G is represented by the difference in line thickness.

  In this case, in the measurement result display device 1, the background color is black, the display color of the grid display 12 is yellow, and the display color of various character information is white. Therefore, not only can the graph Ga and the graphs Gb to Gh be reliably and easily distinguished, but the graphs Ga to Gh can be reliably and easily displayed even when the grid display 12 and various character information are displayed. Can be identified. This makes it possible to reliably and easily read the graph Ga based on the latest measurement data D2 in combination with the grid display 12 displayed superimposed on the frame 11a. In this case, instead of the configuration in which the display mode is changed depending on the display color as described above, the graph Ga is drawn with a thicker line than the other graphs G (the display mode is changed depending on the difference in “line thickness”). An example of a configuration in which the line type of the graph Ga is different from that of another graph G (an example of a configuration in which the display mode is changed depending on the difference of the “line type”), or only the graph Ga It is also possible to adopt a configuration in which the graph Ga of the designated frame 11a is highlighted, for example by blinking display (an example of a configuration in which the display mode is changed depending on the presence or absence of “flashing display”).

  Thus, in this measurement result display device 1, every time new measurement data D2 is generated by the control unit 6 and the graph G based on the measurement data D2 is displayed, it is displayed on each frame 11 before that. A configuration is adopted in which the graph G is moved to the frame 11 positioned in the upper right one and displayed, and the frequency spectrum based on the latest measurement data D2 is displayed as the graph Ga in the foremost frame 11a. Further, in the measurement result display device 1, as described above, in the display process executed in parallel with the series of measurement processes, the configuration in which the grid display 12 is displayed superimposed on the foremost frame 11a is maintained. It has been adopted. Therefore, the measurement result display device 1 can reliably and easily read the latest graph G displayed on the frame 11a based on the grid display 12 and the character information displayed in association with the grid display 12. It has become.

  In this case, in this example, since there are only 8 frames 11a to 11h in the measurement result display screen 10, the frequency spectrum based on the first measurement data D2 is 7 from the time when the graph Ga is displayed in the frame 11a. When the second has passed, as shown in FIG. 2, the frequency spectrum based on the first measurement data D2 is displayed as a graph Gh in the frame 11h, and the graph Ga based on the eighth measurement data D2 is displayed in the frame 11a. It will be in the state. That is, in the measurement result display device 1, when displaying the measurement result in real time in parallel with the series of measurement processes, only the latest frequency spectrum for 8 seconds is displayed in the measurement result display screen 10. It becomes. In the example shown in the figure, as an example, the scale display 13 is displayed at a position of 13.1 kHz (“13.1 kHz” is specified by the scale display 13). Therefore, the frequency (“13.1 kHz” in this example) designated by the scale display 13 and the level (“118.4 dB” in this example) designated by the cursor display 14 in the graph Ga of the frame 11a are shown. The measurement value display 15 is displayed in the measurement result display screen 10 so as to overlap the frame 11a.

  Further, at the time when 8 seconds have elapsed from the time when the frequency spectrum based on the first measurement data D2 is displayed as the graph Ga on the frame 11a, the frequency spectrum based on the first measurement data D2 is not displayed, and the frame 11h. The graph Gh based on the second measurement data D2 is displayed, and the graph Ga based on the ninth measurement data D2 is displayed in the frame 11a. Thereafter, the control unit 6 executes a series of measurement processes in accordance with the set measurement conditions, and ends the measurement process when the measurement process end condition is satisfied (for example, when the end time comes). . As a result, a large number of measurement data D2 generated by a series of measurement processes is stored in the memory 3.

  On the other hand, the measurement result display device 1 is configured such that the measurement result display screen 10 can be displayed on the display unit 5 based on each measurement data D2 stored in the memory 3 after the measurement process is completed. Has been. Specifically, the operation switch of the operation unit 4 is operated to specify the measurement data D2 to display the frames 11a to 11h (graphs Ga to Gh), and the measurement result display screen 10 is displayed on the display unit 5. Let At this time, as shown in FIG. 2, as an example, the frames 11a to 11h (graphs Ga to Gh) based on the eight measurement data D2 generated within 8 seconds from the start time of the measurement process are measured. It is displayed in the result display screen 10.

  In this case, in the measurement result display device 1, when the measurement result display screen 10 based on the measurement data D2 in the memory 3 is displayed on the display unit 5, as an example, the grid display 12 is displayed on the foremost frame 11a. Is used to maintain the state in which the graph Ga of the frame 11a is displayed exclusively for reading the numerical value (the measurement result display screen 10 is displayed, the frame 11a on the foremost side is displayed as “designated measurement”. Example of the configuration of “result display frame”). Further, in the measurement result display device 1, as described above, the graph G (the graph Ga of the frame 11a in this example) of the frame 11 (designated measurement result display frame) on which the grid display 12 is displayed in an overlapping manner is displayed. In addition, a configuration is adopted in which the display is performed separately from the graph G of other frames 11 (with different display colors). Thus, the graph Ga (in this example, the frequency spectrum based on the measurement data D2 generated 8 seconds after the start time of the measurement process) is reliably and coupled with the grid display 12 displayed superimposed on the frame 11a. It can be read easily.

  At this time, when the frame 11 displaying the graph G to be analyzed in detail exists in each frame 11 displayed in the measurement result display screen 10 (for example, it is considered that an abnormal value has been measured). When the frame 11 on which the graph G is displayed exists), the operation unit 4 is operated to specify the frame 11. Specifically, as an example, the frame 11f on which the graph Gf based on the measurement data D2 generated 3 seconds after the start time of the measurement process is displayed is designated (“one of the measurement result display frames is designated. An example) At this time, the control unit 6 moves the grid display 12 that has been displayed superimposed on the foremost frame 11a to the display position of the designated frame 11f as shown in FIG. A grid display 12 is superimposed on the frame 11f for display of the numerical value of Gf.

  In addition, as the grid display 12 moves, the control unit 6 performs character information indicating the relationship between the frequency and level and each coordinate in the frame 11 (in this example, “10 kHz”, “20 kHz”, “30 kHz”, The character information of “40 kHz”, “−130 dB” and “−30 dB”) is moved to the display position of the grid display 12 displayed on the frame 11 f and displayed. Thus, the grid display 12 is displayed in association with the grid display 12 and the grid display 12 displayed so as to overlap the designated frame 11f as compared with the state where the grid display 12 is displayed so as to overlap the frame 11a (see FIG. 2). The graph Gf can be reliably and easily read based on the character information.

  Further, the control unit 6 displays the graphs Ga to Ge, Gg, and Gh of the frames 11a to 11e, 11g, and 11h except the designated frame 11f in the same red color, and the graph Gf of the designated frame 11f in blue. Display the graph of the specified measurement result display frame and the graph of the measurement result display frame excluding the specified measurement result display frame by changing the display mode depending on the display color (line color). An example of a configuration that displays them separately). At this time, the control unit 6 maintains the position of each frame 11 in the direction of the arrow A3 (without changing the position of each frame 11 in the direction of the arrow A3 from the position before the frame 11f is designated). ) The graph Gf of the designated frame 11f is displayed on the graphs Ga to Ge, Gg, and Gh of the frames 11a to 11e, 11g, and 11h excluding the designated frame 11f. As a result, the graph Gf of the designated frame 11f is displayed in the most visible manner without being hidden by the graphs Ga to Ge, Gg, and Gh of the other frames 11a to 11e, 11g, and 11h.

  In addition, as described above, the measurement result display device 1 has a configuration in which the scale display 13 and the cursor display 14 are overlapped and displayed on the frame 11 where the grid display 12 is overlapped, that is, the designated frame 11. Is adopted. For this reason, in a state where the grid display 12 is displayed so as to overlap the frame 11f, the scale display 13 and the cursor display 14 are also displayed so as to overlap the frame 11f. Therefore, by operating the operation unit 4 and moving the scale display 13 to a frequency position (for example, 28.2 kHz) whose level should be referenced in the graph Gf of the frame 11f, the frequency specified by the scale display 13 Then, the measurement value display 15 indicating the level of the portion (in this example, “−94.8 dB”) displayed with the cursor display 14 overlapping in the graph Gf is displayed overlapping the frame 11f.

  Further, the measurement result display device 1 is configured to be able to display an arbitrary comment in association with the designated frame 11. Specifically, for example, in a state where the frame 11f is designated, the operation unit 4 is operated to input a comment associated with the frame 11f. Thereby, as shown in FIG. 3, for example, a comment display 16 (an example of “character information”) “abnormal value exists” is displayed so as to overlap the frame 11f. In this case, in the measurement result display device 1, when the frame 11 other than the frame 11f is designated, the comment display 16 input in association with the frame 11f is not displayed, and when the frame 11f is designated again, “ A configuration is adopted in which the comment display 16 “abnormal value is present” is displayed again overlapping the frame 11f. The character data of the comment display 16 is stored in the memory 3 together with the measurement data D2 and the like.

  Further, in this measurement result display device 1, by operating the operation unit 4 to make it easier to read the graph Gf of the designated frame 11f, as shown in FIG. In addition to being displayed in a filled display color, it is possible to display the graph Gf in an overlaid manner on the filled grid display 12. In the figure, the above-mentioned “filled area” is shown by being filled with a slanting line to the right. In this case, as for the display color that fills the grid display 12, as shown in the figure, the graph G of the frame 11 in which the designated frame 11 overlaps (in this example, the graphs Gg and Gh of the frames 11g and 11h). A transmissive display color can be adopted so as to be visible, and a non-transparent display color can be adopted to further improve the visibility of the graph G of the designated frame 11 (in this example, the graph Gf).

  Furthermore, in the measurement result display device 1, as shown in FIG. 4, the graph G of the frame 11 excluding the designated frame 11 (in this example, the graphs Ga to Ge, Gg) so that the designated frame 11 can be distinguished. , Gh) is displayed with a broken line so that the visibility of the graph G of the designated frame 11 (in this example, the graph Gf) is further improved (the display mode differs depending on the line type). An example of a configuration in which the graph of the designated measurement result display frame and the graph of the measurement result display frame excluding the designated measurement result display frame are displayed separately.

  In the figure, the entire area of the grid display 12 is filled and displayed, and the graphs Ga to Ge, Gg, and Gh are displayed with broken lines, but the grid display is performed with the graphs Ga to Ge, Gg, and Gh displayed with solid lines. It is also possible to adopt a configuration in which the entire area of 12 is filled and displayed, or a configuration in which the graphs Ga to Ge, Gg, and Gh are displayed by broken lines without the grid display 12 being filled and displayed. In this case, instead of the configuration in which the graph G of the frame 11 excluding the designated frame 11 is displayed with a broken line, the designated frame 11 is displayed with a line thinner than the normal display state so that the designated frame 11 can be distinguished. (Example of a configuration in which the display mode is changed depending on the difference in line width (line thickness)), or a configuration in which a display color is displayed lighter than the normal display color (display mode is different depending on the display color (line color)) It is also possible to adopt another example of a configuration in which the values are different.

  Further, in the measurement result display device 1, it is possible to display a grid display 12 by designating two or more frames 11. Specifically, as an example, in addition to the above-described frame 11f, the frame 11b on which the graph Gb based on the measurement data D2 generated seven seconds after the start time of the measurement process is displayed is designated ("any one Another example of “when a measurement result display frame is designated”). At this time, as shown in FIG. 5, the control unit 6 reads the numerical value of the graph Gb while superimposing it on the newly designated frame 11b while maintaining the display of the grid display 12 superimposed on the frame 11f. A second grid display 12 is displayed exclusively. In addition, the control unit 6 displays character information indicating the relationship between the frequency and level and each coordinate in the frame 11b in correspondence with the newly displayed grid display 12.

  At this time, the control unit 6 makes the fill color of the grid display 12 displayed on the frame 11f and the fill color of the grid display 12 displayed on the frame 11b different from each other, and the display color of the graph Gf. The display color of the graph Gb and the display colors of the graphs Ga, Gc to Ge, Gg, Gh are displayed different from each other. Thereby, the grid display 12 displayed so as to overlap the graphs Ga, Gc to Gh and the frame 11f does not disturb the reading of the graph Gb, and the grid display 12 displayed so as to overlap the frame 11b, and The graph Gb can be reliably and easily read based on the character information displayed in association with the grid display 12, and the grid display 12 displayed in an overlapping manner with the graphs Ga to Ge, Gg, Gh and the frame 11b. However, the graph Gf can be reliably and easily displayed based on the grid display 12 displayed overlapping the frame 11f and the character information displayed in association with the grid display 12 without causing a situation that prevents the reading of the graph Gf. Can be read.

  Thus, according to the measurement result display device 1 and the measurement result display method by the measurement result display device 1, the measurement target component is made to correspond to the direction of the arrow A1 (first direction) and the level of the measurement target component is set. A plurality of spectrum display frames (measurement result display frames) for displaying the measured levels of each measurement target component by graphs Ga to Gh in correspondence with the direction of arrow A2 (second direction) intersecting the direction of arrow A1. ) 11a to 11h are shifted in the direction of the arrow A3 (the third direction) and displayed in the order of measurement, and when any frame 11 is designated, the grid display 12 having the same size as the designated frame 11 is displayed. Is superimposed on the designated frame 11 to display the designated frame separately from each frame 11 superimposed and displayed in the measurement order. Unlike the configuration and method in which the graph G of the display 11 is displayed on another display area in the display screen together with the grid display, the designated frame 11 is moved without greatly moving the line of sight from each frame 11 displayed in an overlapped order of measurement. Since the graph G of the designated frame 11 can be read on the basis of the grid display 12 that is displayed so as to overlap, the level indicated by the graph G can be reliably and easily read even by an unfamiliar user. Can do.

  Further, according to the measurement result display device 1 and the measurement result display method by the measurement result display device 1, it is possible to distinguish between the graph G of the designated frame 11 and the graph G of the frame 11 excluding the designated frame 11. Are displayed with different display modes (for example, with different display colors), the level indicated by the graph G is increased to the extent that the specification of the graph G of the designated frame 11 is facilitated. It can be read more reliably and easily.

  Further, according to the measurement result display device 1 and the measurement result display method by the measurement result display device 1, the designated frame 11 is maintained while maintaining the position of each frame 11 in the direction of the arrow A3 (third direction). The level indicated by the graph G is increased by the fact that the specified graph G of the designated frame 11 is more easily identified by superimposing and displaying the designated graph 11 of the designated frame 11 on the graph G of the excluded frame 11. Can be read more reliably and easily.

  Further, according to the measurement result display device 1 and the measurement result display method by the measurement result display device 1, when a plurality of frames 11 are designated, the grid display 12 is superimposed on each designated frame 11 respectively. Since each graph G of each designated frame 11 can be read on the basis of the grid display 12 displayed so as to overlap each designated frame 11 by displaying, each user who is unfamiliar with each The level indicated by the graph G can be read reliably and easily.

  Further, according to the measurement result display device 1 and the measurement result display method by the measurement result display device 1, the scale display 13 and the cursor display 14 for designating the measurement target component in the designated frame 11 are designated. 11, and a measurement value display 15 indicating the level of the measurement target component specified by the scale display 13 and the cursor display 14 in the graph G of the specified frame 11 is displayed superimposed on the specified frame 11. By doing so, the level for the desired frequency in the graph G of the designated frame 11 can be reliably and easily specified by simply reading the measurement value display 15.

  Furthermore, according to the measurement result display device 1 and the measurement result display method by the measurement result display device 1, the comment display (character information) 16 associated with the designated frame 11 is superimposed on the designated frame 11 and displayed. By, for example, comparing the display of the comment associated with the designated frame 11 in a display part different from the position of the frame 11, the displayed comment display 16 is a comment related to any frame 11. It is possible to reliably and easily identify whether there is any.

  In addition, in said measurement result display apparatus 1, although the structure which displays the line graph like graph Ga-Gh in the measurement result display screen 10 as an example of a graph is employ | adopted, it replaces with a line graph, and each A configuration in which display data is generated so as to display a bar graph indicating the level of each component (frequency) may be employed. In the measurement result display screen 10 described above, the “first direction” is the horizontal direction of the screen (the direction of the arrow A1), the “second direction” is the vertical direction of the screen (the direction of the arrow A2), and the “third direction” is displayed. "Is a left-down direction (the direction of the arrow A3). However, the" first direction "," second direction ", and" third direction "are not limited to the above examples. Absent. Further, the measurement result display device 1 provided with the display unit 5 and configured to display the measurement result display screen 10 based on the display data has been described as an example. However, the device (display control) that generates the display data has been described. The measurement result display device can be configured by separately providing the device and the device (display unit) for displaying the measurement result display screen 10 based on the display data.
