Automatic testing system of non-linear thermal parameter of high-power microwave device and testing method thereof

Abstract

The invention provides an automatic testing system of a non-linear thermal parameter of a high-power microwave device and a testing method thereof. The testing system comprises a control circuit module and a microwave circuit module. During a testing process, a vector network analyzer provides a signal source; connection with a correlated port of a microwave testing system is realized; and an MFC program is compiled by using a Microsoft Visual Studio 2012 to control a control circuit part of the system and obtain and display instrument testing data. With the Labview, adata collection program is complied for a six-port amplitude and phase testing module reserved in the system, thereby realizing automatic testing of a non-linear thermal parameter of a high-power microwave device. According to the invention, automatic switching of the testing circuit is realized; and in the testing system, the interface is reserved for the six-port amplitude and phase testing module, so that the cost of phase and amplitude testing of the high-power microwave device is reduced. An objective of automatic testing of a non-linear thermal parameter of a high-power microwave device within a broadband of 2G to 18G can be achieved. The system and method have characteristics of broadband, great convenience, rapidness, and high accuracy.

Description

technical field [0001] The invention belongs to the application field of microwave measurement, and in particular relates to an automatic test system and a test method for nonlinear thermal parameters of microwave high-power devices (high-power microwave devices). Background technique [0002] Microwave high-power devices are an extremely important class of electric vacuum electronic devices, which are widely used in satellite communications, radar and electronic countermeasures and play an important role. As a high-power device, its characteristics can be described by some technical parameters. To evaluate whether a microwave high-power device is qualified or whether it can meet its own application requirements, you can use its technical parameters as a reference. Microwave high-power devices are mainly aimed at amplifying high-frequency signals. The measurement of its technical parameters is designed to use a variety of microwave measurement techniques and high-end instru...

Problems solved by technology

The traditional manual test system is time-consuming and the measurement results are easily affected by the testers, so people began to study the automatic test system to obtain higher measurement accuracy

[0004] At present, people have partially realized the automatic measurement of nonlinear parameters of microwave high-power devices, but these methods all have some problems and defects. These test systems cannot realize the purpose of multi-parameter test for one connection. very strenuous
