Time sharing multiplex measurement system and method based on vector network analyzer

The invention discloses time sharing multiplex measurement system and method based on a vector network analyzer, mainly solving the problems of high configuration cost and low efficiency of the prior art. The measurement system realizes multi-user sharing of one vector network analyzer through a vector network analyzer, a main control computer, a router, two radio-frequency multi-way switches anda plurality of user PCs. The measurement method comprises the steps of: firstly, grouping output ends of the radio-frequency multi-way switches; secondly, establishing a connection between the main control computer and the user PCs; thirdly, realizing the control on the main control computer by operating the PCs to ensures that the main control computer firstly controls the radio-frequency multi-way switches to be switched into a radio-frequency element of the user; fourthly, controlling the vector network analyzer to feed measurement data for the user; and fifthly, after the measurement is finished, carrying out corr
