Integrated network parameter tester and test method applied to pulse regime

Abstract

The invention belongs to a network test technology, and particularly relates to an integrated network parameter tester and an integrated network parameter test method applied to a pulse regime. The tester comprises a built-in pulse generator module and a pulse modulation module connected with the pulse generator module. An excitation signal source module is connected with the pulse modulation module. The pulse modulation module is connected with a pulse high-power S parameter test module. The pulse high-power S parameter test module and a local oscillator signal source module are connected with a mixing receiver module respectively. The mixing receiver module is connected with an intermediate frequency processing module. The intermediate frequency processing module is connected with an embedded computer module through a digital signal processing module. By the tester and the test method, the shortcomings of large volume and high construction cost of the conventional test instrument are overcome; and network parameters can be flexibly and conveniently tested.

Description

technical field [0001] The invention belongs to the network test technology, and in particular relates to an integrated network parameter tester suitable for pulse state and a test method thereof. Background technique [0002] Microwave complex power devices / components are easy to burn out due to high temperature when performing network parameter testing under the long-term continuous wave excitation signal state, so it is very necessary to obtain the response characteristics of the peak large signal state and reduce the average Power is dissipated to protect the DUT. However, the traditional continuous wave state network parameter test equipment cannot solve this problem, and a network parameter test equipment that can generate pulse modulation excitation signals and receive, process and analyze pulse modulation response signals is needed. [0003] At present, in terms of network parameter testing in the pulse state, there are mainly several schemes such as the external ex...
