Teseq NSG 4070B Conducted Immunity Test System

The Teseq NSG 4070B is a multifunctional device for EMC immunity tests, including LF/RF immunity and transient, with a frequency range of 9kHz to 1GHz. Its modular setup uses internal or external amplifiers to enable a large variety of applications, and it is flexible to be used either with its firmware or remote controlled via a PC. The USB port in the front panel allows for easy data transfer via a USB stick.
