EM TEST CWS 500N3 Continuous Wave Simulator 10 Hz 250 kHz

Description

The CWS 500N3 is the state-of-the-art solution in a compact single-box design to test the immunity to conducted low-frequency disturbances and low-frequency magnetic fields. The CWS 500N3 includes a LF signal generator and amplifier, a low-frequency transformer 2:1, a frequency- selective voltage/current meter and load resistors as required by the standards. For remote control via icd.control software both a GPIB and USB interface are available. icd.control software supports the test routines, controls external measuring devices and automatically generates a test report including all test data.

Key applications of the CWS 500N3 are in the automotive and aerospace area. Various international standards and MIL requirements call for magnetic field tests in the low frequency range. Apart from this the automotive industry requires conducted immunity tests with superposed sinusoidal signals on the DC supply voltage (ripple noise). For both applications the CWS 500N3 is the perfect equipment including everything in a single box, necessary for these tests.

The CWS 500N3 meets requirements of SAE J1113-2, ISO 11452-8, DO 160D/E Section 18 and MIL-STD-461 D/E CS101, CS109 and RS101.
