The world’s most comprehensive range of EMC systems for immunity and emissions testing

About Teseq - AMETEK CTS

Teseq develop and manufacture test instruments, software and accessories for EMC emissions and immunity testing. Teseq engineers are experts in their field, who are constantly applying the latest technology, focusing on user-friendly design solutions and incorporating current information on the latest standards.



In radio engineering, an antenna is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver. In transmission, a radio transmitter supplies an electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves).

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.
