The CWS 500N1.3 is the most compact single box test equipment for testing conducted rf immunity per IEC 61000-4-6 Ed. 3 and Ed. 4 and related standards with a frequency range of 10 kHz to 400 MHz. Apart from the 1 kHz 80 % AM signal the generator 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 500N1.3 can be used up to 1 GHz by means of an external amplifier. EM TEST supplies a large range of CDNs, EM clamp and current injection clamps as well as the corresponding calibration accessories. Full compliant levelling can be run from the front panel of the CWS 500N1.3 storing the results in 5 memory spaces is available.
