| Automotive EMC Test Solutions |
The automotive industry has very specific and permanently changing requirements for EMC testing with pulses and waveforms getting more and more complex. As the leading manufacturer of automotive test equipment and member of various national and international standard working groups EM TEST knows the present and the future demands of the car industry. The automotive test equipment listed below are well designed to meet the EMC testing requirements of the automotive industry - today and tomorrow: |
| ESD Generators |
Electrostatic discharge are likely to affect or even destroy electronic components and circuits. EM TEST offers ESD test generators for air and contact discharges up to 30kV as per EN/IEC 61000-4-2 as well as for automotive test requirements: |
| EFT / Burst Generators |
EM TEST offers high-end EFT/burst generators with maximum pulse amplitude and spike frequency capabilities, best user convenience and built-in coupling/decoupling networks, strictly conforming with the latest requirements of EN/IEC 61000-4-4. Apart from standalone EFT/burst generators multi-functional generators with additional testing capabilities (e.g. Surge, PowerFail and Ringwave) are available as compact solutions. |
| Combination Wave/Surge Generators |
Surge pulses occur due to direct or indirect lightning strokes to an external (outdoor) circuit. This leads to currents or electromagnetic fields causing high voltage or current transients. Another source for surge pulses are switching transients originating from switching disturbances and systems faults. Due to the characteristic of the phenomenon nearly every electrical and electronical device may suffer from such lightning events which justifies the necessity of surge tests being widely performed. Surge voltage can reach several thousands of volts and surge current is seen to reach several thousands of amps. EM TEST offers a wide range of Combination Wave generators with different output voltage ranges for various test requirements: |
| Conducted LF/RF Immunity Testing |
EM TEST offers a variety of testing solutions for conducted LF/RF immunity as per EN/IEC 61000-4-6, for BCI (bulk current injection) and magnetic field tests, ripple noise and common-mode testing as per EN/IEC 61000-4-16: |
| Power Quality Testing |
oltage dips, short interruptions and variations of voltage and frequency in supply systems can considerably affect electrical and electronic systems. EM TEST supplies fully compliant solutions for to simulate the various supply voltage anomalies: |
| Programmable AC/DC power sources |
The programmable AC and DC power sources with their wide frequency bandwidth offers powerful waveform generation capabilities for various test applications in the EMC area and for avionics testing. The following multifunctional solutions are available to meet your test requirements: |
| Multifunctional Generators (Immunity) |
The EM TEST modular multifunctional test generators are the ideal starting point to set up an EMC test facility. Most versatile to meet many requirements but also most ecomomic in terms of cost they are designed for fully compliant conducted immunity testing. The following "all-in-one" solutions are available to meet your test requirements: |
| Harmonics & Flicker |
Today's power supplies power regulation systems cause harmonics and interharmonics being fed back into the public supply system. EM TEST offers dedicated solutions for measuring and analysing harmonics and flicker for your needs: |
| Telecom Surge Generators |
Telecom networks and connected telecom systems and devices are subject to lightning strokes and other disturbances and therefore require an effective and carefully selected protection. The EM TEST Telecom Surge generators are specifically desinged to meet the various requirements laid out by ITU, FCC and Telcordia/Bellcore: |
| Voltage Surge Generators |
EM TEST supplies a variety of Voltage Surge generators for safety testing and isolation withstand capability testing. Specifically designed solutions are available for testing audio, video and other ITE products, for testing photovoltaic panels and for protection relays etc.: |
| Coupling Networks for EMC Testing |
EM TEST offers a large variety of coupling/decoupling networks for different test applications for single phase and three-phase mains supplies as well as for signal/data lines and telecommunication lines. Apart from the standard coupling/decoupling networks EM TEST also provides special solutions for higher supply voltages (e.g. 3x690VAC or up to 1,000V DC) and higher currents (up to 100A and more) or for higher surge voltages up to 12kV. |
