The model CWS500D is a generator for testing immunity to conducted disturbances induced by RF fields. It is used for BCI testing in automotive, telecom, IEC and military applications. With a new tool in the ICD software that is included with the generator, users can conduct threshold level testing directly from the software. The CWS500D can be ordered in three versions to fit virtually any user’s needs. It is available without an internal amplifier (10 kHz to 1 GHz); in a 100 W version with internal amplifier (10 kHz to 400 MHz); and a 150 W version with an internal amplifier (100 kHz to 400 MHz).

Multipath Fading Simulator
These RF and IF multipath fading simulators extend the frequency range of the WAVE-3G SIM baseband I/Q product line. The WAVE-3G RFs modular design provides coverage of the cellular/PCS/UMTS/WLAN bands (800 to 6000 MHz). The WAVE-3G IF (70 MHz) features a full digital design implementation that makes it ideal for point-to-point radio or high frequency applications where the user has access to IF 70 MHz circuitry. All three models are available with built-in digital power measurement and noise generator with bandwidths to 20 MHz.
