Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The vector network analyzer is internally provided with a memory for storing all channel excitation information, and is used for generating a specified frequency signal to be output through a formulated port, and the output signal is transmitted back to a receiving board for data processing and acquisition after passing through a piece to be detected. The number of data points M of one frame of data corresponds to the number of excitation points M of a channel, and each excitation point has N+1 bits of data. As shown in fig. 1, when the instrument has N ports, the FPGA reads the first excitation point information to configure the port 1, after the measurement of the port 1 is finished, configures the port 2 according to the first excitation point information, and so on, until the measurement of the nth port is finished, reads the next excitation point information to configure and measure each port respectively, and loops sequentially until the measurement of all the excitation points is finished. As shown in fig. 2, channel 2 is measured after channel 1 is measured until all channels are performed sequentially.
Fig. 3 is a schematic flow chart of an embodiment of a multi-channel measurement method based on a vector network analyzer according to the present invention. The adjustment method is suitable for a multichannel measurement system based on a vector network analyzer, and comprises the following steps of A1 to A4:
step A1: traversing different channel measurement modes according to the channel division requirements; wherein, each channel measurement mode is provided with a plurality of excitation points, and each channel measurement mode is internally provided with an initial excitation point; the initial excitation point is an excitation point confirmed by the FPGA and subjected to port configuration.
In this embodiment, the channel measurement mode to be adjusted needs to be determined before the adjustment is performed, so step A1 specifically includes: determining a plurality of initial measurement channels according to the attribute of each channel in the channel division requirement; traversing different initial measurement channels from the plurality of initial measurement channels according to a port configuration confirmation result uploaded by the FPGA; wherein the port configuration confirmation result includes a channel position; taking the initial measurement channels as references, taking a preset measurement mode as a requirement to perform channel change, and dividing all the initial measurement channels in the channel change into the same channel measurement mode, thereby obtaining different channel measurement modes.
In this embodiment, the initial measurement channels are used as the reference to perform channel change, so that other initial measurement channels are classified, and it is ensured that each channel measurement mode at least includes one initial excitation point. If the same initial measurement channel is in two channel changes, the requirements of the channel changes can be adjusted, and the channel changes can be divided into any channel changes.
In this embodiment, configuration confirmation is performed by the FPGA reaching the real position of the port configuration, and the result of port configuration confirmation is uploaded by the handheld terminal or the intelligent terminal, where the result includes the channel position, so that not only can the authenticity of the offline personnel reaching the real position be ensured, but also the channel position and the dividing requirement are compared, the accuracy of determining the initial excitation points is improved, and it is ensured that each initial excitation point also passes through the real port configuration, and accurate data support is provided for subsequent times comparison.
Step A2: determining different configuration sequences corresponding to the measurement modes of each channel according to the port configuration program of the measurement modes of each channel, and sending the position information of the measurement modes of each channel and the different configuration sequences to a built-in memory so that the built-in memory feeds back the measurement times of the measurement modes of each channel under the respective configuration sequences; the sequence of the port configuration program is set according to the arrangement sequence of the ports.
In this embodiment, according to the port configuration program of each channel measurement mode, different configuration sequences corresponding to each channel measurement mode are determined, specifically: acquiring a configuration object in a port configuration program and a configuration sequence of each configuration; and matching the configuration object with the initial excitation point in each channel measurement mode to determine different configuration sequences corresponding to each channel measurement mode.
In this embodiment, since most port configuration is performed by the FPGA, there will be a corresponding port configuration work schedule and port configuration program. The record can be automatically uploaded by the FPGA or can be uploaded after each port configuration, and is generated by statistics of a background database. In order to ensure the accuracy of the subsequent times comparison, the recorded time period is set according to the arrangement sequence of the ports.
In this embodiment, the position information of each channel measurement mode and the different configuration sequences are sent to the built-in memory. The built-in memory feeds back the measurement times of each channel measurement mode under the respective configuration sequence, and specifically comprises the following steps: and the built-in memory determines a measurement frequency selecting channel according to the position information of the measurement modes of each channel, and the measurement frequency selecting channel respectively uses the different configuration sequences as frequency extracting nodes to extract the measurement frequency of the measurement modes of each channel under the respective configuration sequences from the measurement frequency selecting channel.
The built-in memory is adjusted continuously, so that corresponding measurement times are extracted under different time dimensions and space dimensions through the position information and the configuration sequence, the measurement times of each channel measurement mode under the respective configuration sequence are formed, and then the measurement times are fed back to the system.
Step A3: sequentially taking each channel as a channel to be judged, taking the measurement times of the initial excitation points in the channel to be judged as the reference times of the channel to be judged, determining the port configuration results of each excitation point in the channel to be judged according to the change frequency of the reference times and the measurement times of each excitation point, and then obtaining the port configuration results corresponding to the measurement modes of each channel.
In this embodiment, the step A3 specifically includes:
acquiring the measurement times of a channel to be judged, extracting the measurement times of the channel to be judged according to the initial excitation point and the position information of the update excitation point, and respectively acquiring initial sub-times and update sub-times; the updating excitation points are other excitation points except the initial excitation point in the channel to be judged; each configuration sequence corresponds to an initial sub-number and different update sub-numbers;
according to the configuration sequence, respectively calculating initial times execution conditions between adjacent initial sub-times and update times execution conditions between adjacent update sub-times;
respectively extracting initial times of execution conditions and updating times of execution conditions according to the configuration sequence, and judging whether the completion degree of the extracted times of execution conditions is in a preset change interval or not;
when the configuration sequence is judged to be 1, determining that the port configuration of the updating excitation point is carried out on the configuration sequence;
when the configuration sequence is judged to be 0, determining that the port configuration is not carried out on the updating excitation point in the configuration sequence;
and counting the port configuration conditions in each excitation point, thereby determining the port configuration result of each excitation point in the channel to be judged.
In this embodiment, the measurement modes of the channels are self-determination in the channels, and the determination modes are the same, so each channel is described as a channel to be determined. The excitation points in the channels to be judged can be divided into initial excitation points and updated excitation points according to the attributes, and the initial excitation points are channels which are confirmed by the off-line FPGA and have been subjected to port configuration, so that judgment is not needed, and other sub-channels which are not judged are used as updated excitation points. The measurement times are measured for the whole channel, so that the channel times are extracted first to obtain the measurement times corresponding to the excitation points. The measurement times are associated with configuration sequences, so that each configuration sequence corresponds to an initial sub-time and different update sub-times.
The configuration sequence is used as a node, and the times of execution can be calculated between two measurement times corresponding to the two configuration sequences according to the configuration sequence and aiming at the same excitation point (whether initial or updated), so as to obtain different times of execution or different updating times of execution.
And aiming at the same channel measurement mode, judging whether the change frequency of other updated excitation points on the same configuration sequence is in a preset change interval or not by taking the change frequency inside the initial excitation point as a reference, namely, whether the two times of execution conditions are in the preset change interval or not, so as to judge whether the other excitation points are configured with ports or not. The preset change interval can be set or adjusted by itself according to actual conditions.
The port configuration is used as the node for collecting the times, so that the influence of other environmental factors on adjustment can be avoided, the excitation point is used as a reference, only the change frequency is considered, the variety difference of measurement configuration is avoided, and if the configuration of two sub-channels is far different, dynamic adjustment can be performed by adjusting a preset change interval, so that the adjustment accuracy is improved.
In this embodiment, the number of times of extracting the initial excitation point and the updated excitation point is performed according to the configuration sequence, and whether the excitation points perform port configuration on the same configuration sequence can be known through the comparison of the number of times of executing conditions. Because the growth environments of all the sub-channels are the same or similar in the same channel measurement mode, if the initial excitation point is a confirmed channel which is configured by the ports, if the growth rate and the growth condition (represented by the number of times of execution) of the updated excitation point exceed the preset change interval, the channel is proved to not be configured by the ports in the configuration sequence. Because the configuration sequence is used as the node, the preferred example can also adjust the number of times the sub-channel is applied with the port configuration and the number of times the sub-channel is not applied with the port configuration, and further improves the accuracy of adjustment and the authenticity of the port configuration.
Step A4: and generating measurement port configuration information of the channels according to port configuration results corresponding to the measurement modes of the channels.
In this embodiment, step A4 specifically includes: determining configuration indexes of all the excitation points according to the measurement of the number of times of port configuration and the total configuration number of times in all the excitation points; wherein, each configuration index is preconfigured with different measurement ranges; acquiring a channel division requirement, triggering and setting the corresponding excitation point positions on the channel division requirement by using configuration indexes, and generating measurement port configuration information of a channel after all the excitation points are triggered and set; the configuration map of the vertical measurement port is sent to the configuration device for configuration, and in this embodiment, the configuration index may be related to the number of configurations in step A3.
In the preferred example, the channel division requirements are set in an index triggering mode, the measurement port configuration information of the whole channel is generated, which channels execute port configuration and which channels do not execute can be visually observed, visual data support is provided for subsequent port configuration adjustment planning, supervision strength enhancement and the like, and the accuracy and the globally of port adjustment are further improved.
In addition, the configuration work of the control port can be more intuitively realized through the configuration information of the measurement port of the whole channel.
As shown in fig. 4, when the multi-channel multi-mode measurement principle is as follows:
A. channel 1 uses continuous measurement, channel 2 uses packet measurement, channel 3 uses single measurement, and channel 4 uses hold mode;
B. the channel 1, the channel 2, the channel 3 and the channel 4 are sequentially judged and executed, and the execution is continued when the channel is judged to be continuously measured;
C. judging that the channel is in group measurement and continuing to measure when the measurement times are not full;
D. continuing when the channel is judged to be single measurement and is not finished;
E. and when the channel is judged to be in the hold mode, switching to the next channel.
As an example of this embodiment, the port configuration program is uploaded and obtained according to the port configuration system corresponding to each channel measurement mode. In this example, the port configuration program may also be uploaded by the port configuration system, and the port configuration system automatically configures the channel measurement mode, so that on the premise of ensuring that the port configuration system is actually configured, the port configuration system and the port configuration system are opened, full-automatic adjustment is realized, and the adjustment period may be short, thereby improving the adjustment instantaneity and the efficiency of port adjustment.
