The NSG 3040 System generates electrical fast transient (EFT), surge, and power quality (PQT) tests. It easily fulfills CE Mark testing needs as it is fully compliant to the latest versions of IEC/EN 61000-4-4, -4-5, and -4-11. The NSG 3040 system can perform EFT tests to 4.8 kV and combination wave surges to 4.4 kV, and it can perform dip and interrupt testing. An internal … [Read more...]
Automotive Transient Generator System Avoids Test Set-up Problems
The TGAR transient generator system from AR adapts easily to the various requirements of different auto makers. Each automotive standard has from 5 to 30 transients that must be performed. With the TGAR system, there is no need to move the DUT to different test stations. An onboard oscilloscope simplifies pulse verification and self-calibration. LabView-based software and a … [Read more...]
