DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the attached drawings.

The present invention relates to a measuring device and a measuring method that can perform measurements under external control using remote commands.

As shown in FIG. 1, the measuring device 1 of this embodiment outputs remote commands and their arguments equivalent to operations on a graphical user interface (hereinafter abbreviated as GUI) as SCPI (Standard Commands for Programmable Instruments) commands. It has a remote command generation function to perform the measurement, and is composed of a measuring instrument unit 2 and an external device (personal computer) 3 for remotely controlling the measuring instrument unit 2 and performing various measurements on the measuring object W.

Note that SCPI is a standard regarding command grammar and data structure formulated for remote control commands of measurement devices.

The measuring instrument unit 2 is generally configured to include a measuring section 11, an operation display section 12, a mode specifying means 13, a parameter selecting means 14, a measurement controlling means 15, an interface 16, a command recording means 17, and a file outputting means 18.

The measuring section 11 includes a plurality of modules 11a that can be attached to and detached from each slot of the measuring instrument unit 2 in arbitrary combinations, and performs various measurements on the measuring object W. For example, when the measuring device 1 is configured as an error rate measuring device, the plurality of modules 11a are configured of a PPG module for signal generation, an ED module for signal reception, a synthesizer module for clock signal generation, and the like. Note that the measuring instrument unit 2 is given a unit ID for specifying the unit, and the plurality of modules 11a are also given module IDs for specifying each one.

The operation display unit 12 is configured to include, as a GUI, a power switch, cursor keys for moving the cursor, remote command generation start/end buttons, etc. It is operated when specifying a file name in which to save an SCPI command, selecting parameters for each item that determines the measurement content, starting the measuring section 11, etc.

In addition, when generating a remote command by the operation display unit 12, the remote command including the switching command of the module 11a is linked to each GUI widget (interface parts such as buttons, text boxes, pull-down menus, etc.) of the operation display unit 12. It is being

The operation display unit 12 includes various displays such as a liquid crystal display, and displays a screen that notifies the start of remote command generation and displays parameters for each item that determines the measurement content to be performed by the measurement unit 11. Displays an operation screen for setting, displays measurement results by the measurement unit 11, etc.

Although FIG. 1 illustrates and describes the operation display section 12 as an integrated operation section and display section, the operation display section 12 may be configured with a separate operation section and display section.

The mode specifying means 13 specifies the operation mode of the measuring instrument unit 2 as either a measurement mode or a command generation mode. The measurement mode is a mode in which the measurement section 11 performs measurement and the measurement results are displayed on the operation display section 12. The command generation mode is a mode in which a remote command for remotely controlling the measurement unit 11 by the measurement control means 15 from the external device 3 via the interface 16 to perform measurement is generated. The mode specifying means 13 specifies a mode based on an operation on the operation display section 12.

For example, when the device is started up (when the power is turned on), it is checked whether a specific key other than the power switch is pressed, and if a specific key other than the power switch is not pressed, the measurement mode is specified, and a specific key other than the power switch is When the key (for example, the start/end key 13b of the operation screen 13a in FIG. 3) is pressed, the command generation mode is designated.

The parameter selection means 14 selects parameters to be input and set at the cursor position on the setting screen by operating the widget of the GUI of the operation display unit 12 while the command generation mode is specified by the mode specifying means 13. .

When the measurement control means 15 performs an operation to start measurement with the measurement mode specified by the mode specification means 13, the measurement control means 15 controls the measurement section 11 according to the parameters of each item selected on the setting screen. The measurement target W is measured.

The interface 16 is a channel through which signals are transmitted, an ID (interface ID) is assigned to each channel, and the interface 16 is used for communication with an external device (personal computer) 3 for remotely controlling the measuring instrument unit 2. It is for carrying out. When a remote command is input from the external device 3 to the measurement control means 15 via the interface 16 while the measurement mode is specified by the mode specification means 13, the measurement control means 15 performs measurement according to the input remote command. The unit 11 is controlled to perform measurement on the measurement target W.

When a parameter is selected by the parameter selection means 14 by operating a GUI widget on the operation display unit 12, the command recording means 17 records the remote command and its argument associated with the widget that selected the parameter as an SCPI command. The order in which widgets on the GUI of the operation display section 12 are operated is recorded.

When the output destination is an SCPI file, the file output means 18 outputs the SCPI commands recorded by the command recording means 17 as a text-format SCPI file in the order in which the widgets on the operation display section 12 are operated.

When the output destination is a coded language file (an interpreted programming language or a combined programming language), for example, a Python code file of an interpreted programming language, the file output means 18 outputs the recorded commands recorded by the command recording means 17. Combine the Python send function “com.Send Data0”. Then, a recorded command that is a combination of a Python transmission function and a template code (a code in which the SCPI communication part is written in Python) is incorporated. Furthermore, the IP address and port number specified on the GUI are incorporated into the template code, and the template code is output as a Python Code file.

Next, a method for generating a remote command using the measuring device 1 configured as described above will be described with reference to FIGS. 2 to 4.

When the start/end button 13b of the operation screen 13a in FIG. 2 is clicked, a pop-up screen (not shown) notifying the start of remote command generation appears, and a message indicating that the GUI operation will be converted to an SCPI file appears.

Then, after clicking OK in a pop-up screen (not shown) and specifying a file name for saving the SCPI command equivalent to the GUI operation in the command recording means 17, to indicate to the user that the operation is being recorded, The start/end button 13b is highlighted (for example, in green).

After that, when all operations on the GUI are completed and the start/end button 13b is clicked, the color of the start/end button 13b returns to its original color, and the SCPI command equivalent to the GUI operation with the specified file name is displayed in text format. The SCPI file is saved in the command recording means 17 in the order in which the GUI widgets are operated, and the text-format SCPI file saved in the command recording means 17 is outputted from the file output means 18 as needed by the operation of the operation display section 12. The widgets are output in the order in which they are operated.

Here, a specific example of the operation on the GUI will be shown and explained. When the start/end key 13b on the operation screen 13a in FIG. 2 is clicked (ST1) and the remote command generation function is started (ST2), the parameter "2" is entered in the text box 13c on the operation screen 13a in FIG. .400000" to set the [Bitrate] of the module 11a (module ID: No. 7) of the measuring instrument unit 2 (unit ID: No. 1) (ST3). As a result, as a software operation, the SCPI command ":UENTry:ID1;:MODule:ID7;" including the switching command linked to the parameter, ":OUTPut:DATA:BITRate" and the input value "2.400000" '' is recorded in the command recording means 17 (ST4).

Next, as a user operation, click the button 13d on the operation screen 13a in FIG. ” (ST5). As a result, the software operations include the SCPI command ":UENTry:ID1;:MODUle:ID6;" including the switching command associated with the button 13d, ":INPut:DATA:EQUalizer:LFEQ:SET" and the settings. The combination of "ON" is recorded in the command recording means 17 (ST6).

Next, as a user operation, click the button 13e on the operation screen 13a in FIG. to "ON" (ST7). As a result, the software operations include the SCPI commands ":UENTry:ID1;:MODUle:ID7;" and ":OUTPut:DATA:OUTPut" including the switching commands associated with the button 13e, and the setting "ON". The combination is recorded in the command recording means 17 (ST8).

Then, as a user operation, when all operations on the GUI described above are completed and the start/end button 13b is clicked (ST9), the recorded command recorded in the command recording means 17 is transferred to the GUI. The widgets are outputted from the file output means 18 as a text-format SCPI file in the order in which they were operated, and the remote command generation function is terminated (ST10).

Here, FIG. 4 shows an example of the contents of a file stored in the command recording means 17. To explain the contents of the file in Figure 4, :UENTry:ID 1; means "switch the command output destination to measuring instrument unit 2 (unit ID: No. 1)", and :MODule:ID 7 means "switch the command output destination to measuring instrument unit 2 (unit ID: No. 1)". MODule:ID 6 means "switch the command output destination to the module 11a (module ID: No. 6)", and MODule:ID 6 means "switch the command output destination to the module 11a (module ID: No. 6)". Also, :OUTPut:DATA:BITRate, :INPut:DATA:EQUalizer:LFEQ:SET, :OUTPut:DATA:OUTPut mean each command linked to a widget on the GUI.

In this way, according to the remote command generation function described above, it is possible to switch between the operation of widgets (parts such as buttons and text boxes) on the GUI of a measuring instrument unit equipped with multiple modules and the equivalent remote command. By linking, remote commands equivalent to GUI operations and their arguments are output as SCPI commands together with switching commands to a text-format SCPI file in the order in which widgets on the GUI are operated. This enables customers to enumerate SCPI commands, including accurate switching commands, in the order in which they were operated and output them to a file, which is equivalent to operations on the GUI of a measuring instrument unit equipped with multiple modules, and provides instructions on how to use remote commands. There is no need to read manuals, measurement work can be carried out in a short time, and there is no chance of misinterpretation of the instruction manual, so there is no time loss such as rework, and usability can be improved.

Next, a process for outputting the recorded commands recorded in the command recording means 17 as a file completed as a program will be explained with reference to FIGS. 5 to 7.

If the coded language output by the file output means 18 is Python Code, the recorded command recorded in the command recording means 17 is combined with the Python transmission function "com.Send Data0" (ST11).

Next, the recorded command of ST11 is incorporated into the template code (code in which the SCPI communication part is written in Python) (ST12). For example, the recorded command of ST11 is incorporated into the "ZZZZ" portion of the template code shown in FIG.

Next, the IP address and port number specified on the GUI are incorporated into the template code of ST12 (ST13). For example, the IP address and port number specified on the GUI are incorporated into the "XXXX" and "YYYY" portions of the template code shown in FIG.

Then, the template code of ST13 is output to a file as Python code, and the process ends. For example, the template code shown in FIG. 6 is output as a Python Code file shown in FIG. 7. In the Python Code file in Figure 7, the parts corresponding to "XXXX" and "YYYY" in Figure 6 contain "5001" and "127.0.0.1" as the IP address and port number specified on the GUI. Incorporated. In addition, in the part in FIG. 7 corresponding to "ZZZZ" in FIG. 6, "com.SendData(':UENTry:ID 1;:MODule:ID 7;:OUTPut:DATA:BITRate 2. 400000'), com.SendData(':UENTry:ID 1;:MODule:ID 6;:INPut:DATA:EQUalizer:LFEQ:SET ON'), com.SendData(':UENTry:ID 1;:MODule :ID 7;:OUTPut:DATA:OUTPut ON')" is incorporated.

Incidentally, in the above-described embodiment, the case where one measuring instrument unit 2 including a plurality of modules 11a is remotely controlled by one external device 3 was explained as an example, but the present invention is not limited to this. . For example, as shown in FIG. 5, there is a configuration in which a plurality of measuring instrument units 2 each having a plurality of modules 11a are prepared, and one external device 3 remotely controls the plurality of measuring instrument units 2 at the same time. It is also possible to have a configuration in which the device 3 remotely controls a plurality of measuring instrument units 2 while sequentially switching them. In this case, in order to support recording and file output of SCPI commands including switching commands by operating the GUI described above, each of the plurality of measuring instrument units 2 is given a unit ID that identifies each one, and each measuring instrument unit The modules 11a included in the measurement unit 11 of No. 2 are also assigned module IDs that identify each module.

Furthermore, in the above-described embodiments, Python, an interpreted programming language in which programs can be executed as is, is used as an example of the coded language, but the present invention is not limited to this. For example, instead of Python, an interpreted programming language such as Perl, PHP, Ruby, Java Script, LUA, TCL/TK, Batch, Power Shell, Bourne Shell, TCSH, etc. may be used.

Note that a combined programming language (eg, C, C++, C#, Java, Pascal, Fortran, COBOL, Basic, etc.) may be used instead of the interpreted programming language. In this case, compilation is required to run the program.

As described above, in this embodiment, the recorded commands recorded by the command recording means 17 (SCPI commands equivalent to GUI operations with a specified file name) are stored as SCPI files in text format in the order in which GUI widgets are operated. The recorded commands are output as codes in Python (an example of an interpreted programming language), which is a de facto standard for interpreted programming languages. As a result, the generated file becomes the code itself, and the procedure operated by the customer on the GUI can be executed as a remote command. As a result, there is no need for the customer to incorporate SCPI commands into a program, or to create a program that reads the output SCPI text file and outputs it as a remote command, and there are no problems associated with program embedding. It becomes possible to eliminate the problem.

Although the best mode of the measuring device and measuring method according to the present invention has been described above, the present invention is not limited to the description and drawings based on this mode. That is, it goes without saying that all other forms, embodiments, operational techniques, etc. made by those skilled in the art based on this form are included in the scope of the present invention.
