    EMC immunity test system for the frequency range 15 Hz to 150 kHz. It consists of a sine wave generator, power amplifier, EUT monitoring interfaces and different coupling units depending on the application, i. e. NSG 4060-1 for testing IEC / EN 61000-4-16 including short duration disturbance tests for DC, AC from 162/3 Hz to 200 Hz and test levels up to 300 V. Voltage testing according IEC / EN 61000-4-19 requires the combination with CDND M316-2. It includes the differential mode coupling and decoupling and the required 10 Ω impedance of the disturbance source. Current testing according IEC / EN 61000-4-19, e.g. testing electricity meters, requires the combination with CT 419-5. The powerful and easy to use firmware makes the NSG 4060 independent from an external PC and control software, however it can also be remote controlled for system operation. Part of NSG 4060’s delivery is an USB-to-serial / optical converter which offers potential free remote control.
