AR offers a Tubular Wave Coupler Series for immunity testing and emission measurement of devices with power leads or other connection lines with a coupling efficiency better than 20 dB. Immunity testing can be performed similar to a BCI probe test from 400 MHz to 3 GHz. Emission testing can be performed similar to a current probe test from 150 kHz to 3 GHz. The BI30000 Series couplers are ideally suited for Automotive RF Conducted Immunity Testing of the wire harnesses.
