Testing system and method for conducted susceptibility of cable bunch injection

Abstract

The invention discloses a testing system and method for conducted susceptibility of cable bunch injection. The system comprises a control module, a signal generation module, a signal amplification module, a coupling module, an injection clamp, a monitoring clamp and a signal measurement module, wherein the control module is used for generating a control signal controlling the signal generation module and the signal measurement module to work; the signal generation module generates a standard testing signal according to testing standards under the control of the control module; the signal amplification module amplifies the standard testing signal generated by the signal generation module and then sends the standard testing signal into the coupling module for coupling; the coupling module isused for coupling the standard testing signal amplified by the signal amplification module to the injection clamp; the injection clamp is used for injecting the amplified standard testing signal intoa to-be-tested cable; the monitoring clamp is used for picking up a signal conducted by the to-be-tested cable and transmitting the signal to the signal measurement module; the signal measurement module is used for reading measurement data of the coupling module and monitoring clamp under the control of the control module. The testing system and method for the conducted susceptibility of the cable bunch injection have the advantage that on the basis of no additional purchase of other equipment, it can be ensured that testing is started from the testing frequency below 4kHz.

Description

technical field [0001] The invention relates to the technical field of cable bundle injection conduction sensitivity testing, in particular to a cable bundle injection conduction sensitivity test system and method. Background technique [0002] With the development of science and technology, the test frequency requirements of CS114 (cable bundle injection conduction susceptibility test) specified in GJB151 (requirements for electromagnetic emission and susceptibility of military equipment and subsystems) are expanding to lower frequencies. The start frequency of CS114 test in different versions of the standard: GJB151A-97 starts the test at 10kHz, and GJB151B-2013 has extended the start frequency of some platform devices down to 4kHz. Most of the current test systems start testing at 10kHz. Unless the hardware is upgraded, it cannot meet the test requirements starting at frequencies below 4kHz. [0003] That is to say, in order to realize the CS114 test system solution star...

AI Technical Summary

Problems solved by technology

[0004] 1. The cost of replacing the power amplifier and other supporting hardware is too high, which is equivalent to buying a new test hardware system

[0005] 2. Even if the hardware is updated, there is currently no CS114 test system that can start from 4kHz or below 4kHz on the market, and can only start testing from 4kHz
