Multi-user multi-port expansion method and system based on vector network analyzer

Abstract

The invention discloses a multi-user multi-port expansion method based on a vector network analyzer, and the method comprises the following steps of establishing a port list; establishing a total channel list; establishing a user list, and starting a data updating processing flow; monitoring the connection state of a user in real time, adding the user to the user list when the user accesses the connection, distributing port resources and channel resources for the user according to the measurement items, and updating in real time through the data updating processing flow; and when the user quits the connection, moving the user out of the user list, and releasing the port resources and the channel resources occupied by the user. The invention also discloses a multi-user multi-port expansionsystem based on the vector network analyzer. By adopting the invention, reasonable expansion of port resources and network analyzer channel resources can be realized, and the multi-user multi-port expansion method and system based on the vector network analyzer has the advantages of strong real-time property, high precision, good flexibility, rapidness and convenience.

Description

technical field [0001] The invention relates to the technical field of measuring equipment, in particular to a multi-user multi-port expansion method based on a vector network analyzer and a multi-user multi-port expansion system based on a vector network analyzer. Background technique [0002] A vector network analyzer is a test device for electromagnetic wave energy. It can not only measure the magnitude of various parameters of a single-port network or two-port network, but also measure the phase. The vector network analyzer can display the test data with a Smith chart. It is widely used in antenna testing, radio frequency, microwave circuit testing, component measurement and inspection. The method of using a vector network analyzer is to inject radio frequency energy of a certain frequency through a port, and then measure the received radio frequency amplitude and phase delay for all ports to analyze the incident power, reflected power and phase difference of each port ...

AI Technical Summary

Problems solved by technology

[0003] At present, most vector network analyzers use two ports, which can only be connected to one device under test at the same time, and cannot be used by multiple devices under test. When measuring a device under test with N ports, since the vector network analyzer only has two ports, it is often necessary to measure 2 N Second, the utilization rate is low; at the same time, in the prior art, neither the port resources nor the channel resources of the network analyzer are properly allocated, nor are more computers added to the network, so the number of user ports cannot be flexibly configured or changed
