Automotive transient generators are typically benchtop, but heavy equipment. When doing testing on three phase power lines systems usually require much larger coupling/decoupling networks which substantially increase system size. EM test environments with ground planes with connections to earth are required to safely use transient generators.
Pulse 1. A simulation of transients due to supply disconnection from inductive loads; it applies to a DUT if as used in the vehicle, it remains connected directly in parallel with an inductive load.
Pulse 2a. Simulates transients due to a sudden interruption of currents in a device connected in parallel with the DUT due to the inductances of the wiring harness.
Pulse 2b. Simulates transients from DC motors acting as generators after the ignition is switched off.
Pulse 3a/3b. Occurs as the result of switching processes. The characteristics of this pulse are influenced by distributed capacitance and inductance of the wiring harness.
Pulse 4. The voltage reduction caused by energizing the starter motor circuits of the internal combustion engines. Pulse 4 variants. Most manufacturer variations of pulse four are generally much more complicated. For example, Ford requires up to four arbitrary generators with four outputs to be perfectly synchronized.
Pulse 5. Simulation of a load dump transient occurring in the event of a discharged battery being disconnected while the alternator is generating charging current with other loads remaining on the alternator circuit at this moment. Magnetic field immunity. Simulates magnetic fields generated by electric motors, daytime running lamps, etc. for DUTs with magnetically sensitive devices. Transformer coupled sine waves. Sinusoidal noise coupled on battery lines. Often referred to as “ground shift”.
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.
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
The EM Test 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:
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.
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:
