Teseq (Schaffner) NSG4070

Teseq NSG 4070 Conducted RF Immunity Test SystemThe Teseq NSG 4070, successor of the NSG 2070, is a multifunctional EMC immunity test system. Its large frequency range from 9 kHz to 1 GHz and its modular set-up using internal or external amplifiers enable a large variety of applications including tests according to IEC 61000-4-6, various BCI applications as well as signal generator and power meter for test systems as per IEC 61000-4-3, IEC 61000-4-20, IEC 61000-4-21 and many other applications. The powerful and easy to use fi rmware makes the NSG4070 independent from an external PC and control software, however it can also be remote controlled for system operation. A state-of-the-art data transfer of test and measurement data for documentation is provided by USB stick to be plugged into the front panel.Features of the Teseq NSG4070 include:

Integrated signal generator 9 kHz to 1 GHz

3 power meter inputs 9 kHz to 1 GHz

Integrated power amplifier module for diffe applications

Multiple EUT monitoring options

5.7“ TFT color display

Internal, menu-based control software

Basic remote control software and report generator included
