Test Equipment Description

EM Test AMP 200N Application:

AMP 200N - Low-frequency signal source for supply simulation and magnetic field testing

The AMP 200N has been designed as a low-frequency signal source 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 customised 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.

AMP 200N - Signal generator/amplifier solution for ripple noise and magnetic field testing

The AMP 200N unifies a low-frequency signal generator and a powerful amplifier module giving a maximum amplitude of 150V peak-to-peak as required e.g. by Ford EMC-CS-2009.1. It generates both sinusoidal and transient signals. Equipped with a DDS it generates any sinusoidal signal with a frequency up to 250kHz. The AMP 200N is controlled by the EM TEST AutoWave in order to generate any sinusoidal or non-sinusoidal/transient signals and is therefore fully supported by the autowave.control software with its exhaustive library of pre-programmed standards and its outstanding reporting and documentation capabilities.

The AMP 200N can also be used for magnetic field testing using a Radiation Loop and Loop Sensor. Extended by the optional measuring module the AMP 200N offers means for frequency-selective current measurement, voltage measurement and measurement of the magnetic field strength.
