The NSG 4070C-LFCP is a universal device for standard-compliant and development-accompanying EMC immunity tests in the application area of magnetic field testing in the close proximity according to IEC / EN 61000-4-39 and IEC / EN 60601-1-2. The NSG 4070C-LFCP integrates signal generator, directional coupler, power amplifier, power meter and EUT monitoring interfaces. The NSG 4070C-LFCP can be operated quickly, conveniently and easily via the front panel as a free-standing device. Test and measurement data can be conveniently transferred for documentation purposes via a USB stick. The NSG 4070C-LFCP can be remote controlled via LAN, electrical or optical RS232 as well as USB.

The wide frequency range of the signal generator and the power meter offer the possibility to connect external amplifiers and directional couplers. In combination with a remote control software, external power amplifiers and directional couplers, further applications can be covered, such as testing of conducted disturbances induced by high frequency fields according to IEC / EN 61000-4-6, automotive BCI tests e.g. according to ISO 11452-4 as well as high frequency electromagnetic fields according to IEC / EN 61000-4-3 or IEC / EN 61000-4-20. For EUT monitoring, the NSG 4070C-LFCP offers a variety of interfaces for flexibility in laboratory use.

In order to start with predefined parameter settings the optional test software icd.control is recommended. The software offers a large standard database and predefined drives for using external measuring devices. More complex systems including radiated tests can be controlled by using the software solution CIS (Compliance Immunity Software).t also allows for all coupling methods to be simply and easily connected and calibrated.
