Test Equipment Description

The Teseq NSG 4070C-35 Compact immunity test system NSG 4070C, 4 kHz - 1 GHz RF generator and power meter (with integrated power amplifier 35 W module 150 kHz - 230 MHz) is a multi-functional device for carrying out EMC immunity tests to accompany development and conformity testing in accordance to EN/IEC 61000-4-6, Namur and several automotive BCI standards. Anyone who spends a considerable amount of time on test level setting, connecting EUT monitoring or writing test reports can now carry out immunity testing in a much more efficient manner with the 4th generation of NSG 4070. Its modular set-up using internal or external amplifiers enables a large variety of applications. The powerful and easy to use firmware makes the NSG 4070 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.

Teseq NSG 4070 - How to Setup Remote Control to PC

The optical link adapter can be very difficult to connect and should be avoided unless absolutely needed. Utilizing a LAN cable, connecting to the Teseq NSG 4070 software for remote use is simple and completed in a few simple steps. The EMC Shop stocks the Teseq NSG 4070 and all the accessories to complete RF conducted immunity testing to IEC 61000-4-6, ISO 11452-4MIL-STD 461 CS114 and other test standards.
