EM TEST CWS 500N2 Continuous Wave Simulator

Description

CWS 500N2 Simulator for BCI (Bulk Current Injection Testing)

EM TEST CWS 500N2 Continuous Wave Simulator is designed for testing rf conducted immunity to narrowband radiated electromagnetic energy. Apart from the injection probe and the monitoring probe everything is in the box; controller, signal generator, amplifier, directional coupler and RF power measurement of up to three signals in parallel. A built-in RF switch allows to connect and use any external amplifier to extend the system’s capabilities.

The CWS 500N2 is also designed to be used for tests with CDNs and EM clamps for tests according to EN/IEC 61000-4-6 and related standards.
