IEC 61000-4-6 / EN 61000-4-6
The CWS 500N1.3 and CWS 500N1.4 are 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 between
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.
