A matrix comprehensive tester and a testing method

Abstract

The invention provides a matrix comprehensive tester and a testing method. The matrix measuring instrument can achieve automatic switching of channels and can improve the testing efficiency and safety; with a built-in universal meter, an external oscilloscope, an external power source and an external resistor, many testing modes can be achieved, so that the simple instruments and apparatuses can meet the requirement for multiple kinds of tests; by designing automatic testing software and testing procedures, testing methods can be standardized and unified and the consistence of test data in all phases in an apparatus delivery period is guaranteed; test data can be interpreted and stored automatically, so that interpretation and management of test data are facilitated.

Description

technical field [0001] The invention belongs to the technical field of automatic testing, and in particular relates to a matrix comprehensive tester and a testing method, which are mainly used to realize static impedance, command testing, and automatic testing of input and output impedances of satellite-borne electronic products. Background technique [0002] With the growing development of the national aerospace industry, more and more spacecraft models are becoming more and more intensive. In addition, due to the influence of emerging design concepts such as integrated electronics, the interfaces of on-board electronic equipment are highly dense. The static impedance test and input of the interface , output command test, etc. as many as hundreds, the traditional test adopts manual test, the test method is cumbersome, and the test process is easily disturbed by human uncertain factors; the repetitive test takes a long time and the work efficiency is low; the manual test is c...

[0002] With the growing development of the national aerospace industry, more and more spacecraft models are becoming more and more intensive. In addition, due to the influence of emerging design concepts such as integrated electronics, the interfaces of on-board electronic equipment are highly dense. The static impedance test and input of the interface , output command test, etc. as many as hundreds, the traditional test adopts manual test, the test method is cumbersome, and the test process is easily disturbed by human uncertain factors; the repetitive test takes a long time and the work efficiency is low; the manual test is carried out with self-made tooling For testing, too many manual operations can easily lead to misoperation; manual recording of test data is not conducive to the interpretation and management of test data
