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.

A matrix comprehensive tester and a testing method

The invention provides a cable static impedance automatic tester and a test method, belongs to the field of electrical test, and is mainly used for cable network connectivity testing on a spacecraft/missile, capable of measuring static impedance between any direct connection/cross cable and a cable. The tester includes a PXI chassis (including an embedded controller), a PXI digital multimeter, anda PXI matrix switch. The common ends of a first matrix switch and a second matrix switch are connected to the positive and negative terminals of the digital multimeter respectively. A testing persondoes not need to use a handheld three-purpose meter to perform point-by-point testing and manual recording, only needs to use an adapter cable to connect a test interface and uses a host computer to import a cable measurement netlist and generate a test vector, the subsequent measurement process can be automatically completed, and the test report is automatically generated according to the template setting, which greatly improves the test efficiency, reliability and safety. The system is designed to be compatible with a cable network test with 196 * 196 terminals.

Cable static impedance automatic tester and test method

The invention relates to an initiating explosive device test system and relates to the field of automated testing The initiating explosive device test system comprises a matrix switch module, a circuit protection module, a digital multimeter and a PXI portable computer which successively communicate with one another The matrix switch module communicates with an external test object and the PXI portable computer communicates with the matrix switch module The test node of the external test object is connected with the input end of the matrix switch module Under the control of the PXI portable computer, the matrix switch module is connected to the positive and negative poles of the digital multimeter After measurement by the digital multimeter, the PXI portable computer gives a test result The initiating explosive device test system realizes the accurate test of the resistance value of the initiating explosive device, and has obvious advantages in the aspects of test accuracy, testefficiency, data interpretation, result storage, data envelopment analysis and the like

Initiating explosive device test system

The invention relates to a rocket testing system comprising a signal transferring device, a multiplexing switch module, a universal meter module, a multi-functional board card, a relay module, and a controller. All leading-out points of a rocket are divided into two paths, including a positive path and a negative path, for leading out; a point for testing point access is selected based on software configuration; and voltage testing, resistance testing, current testing, command testing, link signal function testing and digital quantity testing can be realized. The testing system has advantages high universality, flexible testing, and comprehensive coverage.
