EM TEST is the leading manufacturer and supplier of EMC generators for the automotive industry and among the leaders for IEC, telecom, medical and component testing.



Leading manufacturer and supplier of EMC generators for the automotive industry and among the leaders for IEC, telecom, medical and component testing.


EM TEST equipment offers the capability to match most test routines exactly to spec and to modify existing spec-based routines as required. Test routines are easy to handle, sophisticated and technologically state-of-the-art. Software programs are exceptionally simple and generators are extremely reliable.


Automotive Battery Simulators

Battery simulators replace the vehicle battery in the test environment. These sources must fulfill various criteria concerning power rating, voltage, fast slew rate, very low impedance, low noise, etc. depending on the particular application. Pulse 2b, pulse 4, sine wave noise and other complex simulations are all supported. Our one, two and four-quadrant amplifiers are perfectly suited for ISO 7637 compliant simulated conducted transient testing.

Automotive Electrical Disturbances

Automotive electrical disturbances occur regularly in the vehicle primarily due to switching of various vehicle components and affected by the vehicle harness and other parallel loads. There are both emissions and immunity tests required by the standards, of which there are many. The main standards like ISO 7637-2 and ISO 16750-2 define both how these pulses must be simulated and how they are measured and with what limits.

Automotive Supply Voltage Variations

Transient immunity standards like LV 124 and ISO 16750 define immunity tests for real-world problems occur on battery systems including supply voltage dips, dropouts, and various types of ripple.
