Teseq NSG 4031 Broadband Immunity Test System
The Teseq NSG 4031 Broadband Immunity Test System is a 150kHz to 80MHz transient immunity generator designed to generate test waveforms in compliance with IEC/EN 61000-4-31. Teseq NSG 4031 test systems feature a white noise generator with four different band filters, which enables band-limited testing as called for by future test standards. An internal power amplifier featuring over 80W of output power adheres to test levels 1-3 as described in Table 1 of IEC / EN 61000-4-31 and includes an optional 2dB attenuator for cases of severe DUT mismatches. The three front panels allow for simple test level settings procedure, and an internal power meter displays forward power and the VSWR of the connected setup. Navigate the Teseq NSG 4031 via a 5.7" color display.
