EM TEST CWS 500N1 Continuous Wave Simulator 80W

Description

The CWS 500N1 is the most compact single box test equipment for testing conducted rf immunity as per IEC 61000-4-6 and related standards with a frequency range of 100kHz to 300MHz. Apart from the 1kHz 80% AM signal the CWS 500N1 also generates a 2 Hz 80% AM signal to test medical appliances and a 1 Hz PM signal with 50% duty cycle required to test safety equipment like fire alarms. Equipped with a 1 GHz current monitor the CWS 500N1 can be used up to 1 GHz by means of an external amplifier.

One single box replaces five dedicated items. Hence setting up for testing is much easier and faster, saves space, is much more reliable and you achieve a higher reproducibility of the test results.

The CWS 500N1 offers the best benefit-to-cost ratio. Calibration/leveling of the test set-up has never been easier; terminate the DUT port with the calibration adapter, connect this to the 150ohm-to-50ohm matching impedance and lead its output to the Cal Input. Start the calibration routine and you are done in a minute.

The signal generator delivers signals up to 300MHz for the internal amplifier while the frequency range can be extended for 9 kHz to 1 GHz using an external amplifier.
The powerful, top-performance built-in class A amplifier allows to test up to 30V using any kind of coupling/decoupling device (CDNs, EM clamps, current injection clamps). The built-in 1GHz current monitor offers the ability to control the injected current signal while using injection clamps.

The EM TEST specific Quick Start test routine complemented by pre-programmed Standard Test routines make the CWS 500N1 completely independent from operation by software. icd.control software extends the capabilities of the CWS 500N1 to a complete rf test system, e.g. performing enhanced calibrations (customized voltage level or frequency range) through the built-in power meter.
