The callback and storage functions provided by the current vector network analyzer can only store the measurement data smaller than or equal to the port number according to the measurement port number of the network analyzer, and only can callback the measurement data not exceeding the port number during callback; and does not support storing or recalling portions of test data. The file processing system provided by the patent can flexibly combine a plurality of n-port test data into m-port test data (m is more than or equal to n), so that the number of the ports of the combined measurement result is larger than that of the ports of the network instrument; the multi-port test data can be split into test data with smaller ports, so that a user can conveniently guide the test data into a network instrument to observe a measurement result; and part of test data of the designated port can be intercepted, so that flexible and various measurement result observation modes are provided for users.
The 5G age with high speed, low time delay and large capacity has higher requirements on the performance of components, increased test frequency bands, increased test bandwidth and increased test frequency, so that the number and integration level of the components are increased. Antenna testing requirements for Massive MIMO technology are increasing. The vector network analyzer is widely applied to test performance parameters such as intermodulation, loss, transmission delay and the like among receiving and transmitting channels of the antenna, and along with the increase of the number of receiving and transmitting channels of the antenna, the test requirement of the multi-port vector network analyzer is also increasing. How to use the existing 2-port or 4-port vector network analyzer to carry out multi-port test, avoids purchasing expensive multi-port vector network analyzers, saves test cost and becomes a requirement of users.
The current vector network analyzer can store and recall the current measurement results, but is limited to storing the measurement results which are smaller than or equal to the number of ports of the network analyzer, and can not store or recall partial test results, or integrate the test results of different ports into the measurement results of more ports, or split the multi-port test results into the measurement results of a few ports.
The file storage and callback function provided by the current vector network analyzer is to store or callback the test result of the current measurement setting, cannot acquire a certain frequency band test result or integrate or split the test result, and certain software provides a post-processing mode, however, the operation mode is complex, cannot be integrated with the network analyzer, is inconvenient to use, and cannot be compared with the current test result in real time.

{S11、S12、S13、S14、
S21、S22、S23、S24、
S31、S32、S33、S34、

when integrating, the parameters of the integrated files can come from different files, different files can be distinguished by using colors, different files are marked by different colors in a file list, and the colors in mapping are consistent with the colors of the files, so that a user can know the data sources conveniently.
When integrated, the source of the parameter Pj may be an ideal value and a user-specified value, and if no source is specified, default to 0 or a user-specified value.
A file processing method suitable for a multiport network instrument specifically comprises the following steps:
step 1: the system provides a user interaction interface, and after a user adds a file to be processed, the system firstly analyzes whether the file is an S parameter file according to a file format;
step 2: the correct file path and file name are displayed in the file list, and the files can be distinguished by color or by over-coding;
step 3: the user can specify the processed file data format, including the port number, the file header information, the data range, the data format and other information of the file, and if not, the processed file data format is consistent with the selected file format;
step 4: the parameter list displays the parameter information of the selected file, and the parameter mapping area displays the parameter matrix;
step 5: the mapping relation between the parameters before or after the processing can be distinguished by the color, and the sources can be distinguished in the form similar to the labels in the display of the mapping area;
step 6: let n be the source port, then according to the S parameter definition: sij=i×n+j, and the relation matrix P between the parameters before and after the process is P [ k, l ] =i×n+j.
The invention makes the port number of the file after processing inconsistent with the port number before processing through splitting and integrating operation, and increases the flexibility of S parameter file processing; the data format and range of the file can be changed, so that the user can conveniently extract part of test data; and the split and integrated parameter mapping is provided by using an interface display mode, so that the user can operate conveniently.
