EM TEST AMP 200N Low Frequency Signal Source
Description
EM TEST AMP 200N Low Frequency Signal Source is designed to generate sinusoidal signals used to simulate ripple noise and ground shift noise as required by a variety of standards in the automotive industry e.g. as per Ford EMC-CS-2009.1, CI 210 and CI 250 as well as RI 150.
The AMP 200N is controlled by the EM TEST Autowave to also allow the generation of non-sinusoidal and customized signals. Additionally, the AMP 200N can be used to generate magnetic fields by means of a radiation loop or small Helmholtz coils as per RI 140 of Ford EMC-CS-2009.1.
Features

- Built-in LF amplifier, 250W
- Output voltage max. 140V p-p, 50V rms
- Output current max. 5A rms
- Programmable DC voltage offset
- Controlled by Autowave and autowave.control via Framebus
- Integrated voltage measurement 10Hz – 250kHz (optional)
- Integrated field strength measurement (optional)
- Integrated frequency-selective current measurement 10Hz – 250kHz (optional)
- Safety interlock
