Abstract

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 and a 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 corresponding processing on the data on the PCs by the user. Compared with the prior art, the invention reduces the cost of configuring production line apparatus, reasonably utilizes traditional resources, shortens the time, and improves the efficiency.

Description

technical field

[0001] The invention belongs to the field of test and measurement, relates to the use of a vector network analyzer, and is mainly used in the measurement and automatic control of the radio frequency microwave industry and other industries. Background technique

[0002] The vector network analyzer is an indispensable instrument for the RF microwave industry, but its cost is expensive. The vector network analyzer used in R&D and production generally has a frequency range of several hundred kHz to tens of GHz, and the price of the simplest configuration Also in the tens of thousands of dollars or more. For microwave radio frequency production enterprises, each production line is equipped with several such devices, and the corresponding cost is huge.

[0003] Currently, the use of vector network analyzers is single-user operation, that is, one-to-one. When measuring a radio frequency device, it is necessary to calibrate the vector network analyzer first, then c...
