EM TEST CWS 500N2 Continuous Wave Simulator EN/IEC 61000-4-6

Description

Bulk Current Injection (BCI) is a test procedure to proof the immunity to electrical disturbances by narrowband electromagnetic energy. The test signal is injected by means of a current injection probe physically being a current transformer laid around the wiring harness. Immunity tests are performed varying the level and the frequency of the injected test signal. The BCI test method is widely known in the automotive industry as well as in the military/aircraft industry to test single components of a complex system.

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

The CWS 500N2 is the first compact solution world-wide 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.

Despite of being that compact the CWS 500N2 is a very flexible solution and can be used in the laboratory as well as everywhere in the field. Setting up a test is done very quickly with a minimum effort for cabling of the test equipment. There are only two leads; the rf power lead to the input of the injection probe and the return lead from the monitoring clamp. The user doesn't need to be an expert to run reliable and reproducible tests.

A powerful software tool including extensive reporting features and instrument driving capabilities masters the test procedures. All operation is done by means of icd.control software.
