LXI-based Impulse Noise Integrated Test System

Abstract

For a time-domain parameter, the pressure-time curve should be described in addition to describe its peak rule. In order to accurately measure the impulse noise generated during firing of guns and other weapons, a remote operation and wide area shock wave and noise test system is designed. Through the compatibility design of the front-end conditioning module, the switch input of the full bridge differential signal and single ended signal is realized, and the acquisition device is built based on the LXI1.4 standard, realizing the remote control of the regulator. The test system is completed at the same time of measuring shockwave and noise, the two curves, the equivalent sound pressure level size. The test system provides some reference for the measurement of the synchronization of impulse noise.
