Pulse 3a / 3b Generator ISS-7630 - NOISE LABORATORY CO.,LTD.

Automotive Transient Surge Simulator(ISS/JSS) Pulse 3a / 3b Generator ISS-7630

Simulation of transients which occur as a result of the switching processes. The characteristics of these transients are influenced by distributed capacitance and inductance of the wiring harness.

EMC Testing

Features

- Compliant tests to ISO 7637-2 (2011) Standard (Pulse 3a/Pulse 3b generator)
- Stand-alone usage possible with 60V 30A CDN built-in.
- Frequency sweep (10 kHz – 100 kHz – 10 kHz) test possible (Option)
- Faster than 3.5ns rise time realized so as to conduct more severe test than the Standard.
■Output waveform

■Difference of the impulse response among measurement probes
Since Pulse 3a / 3b contain high frequency components, the waveform measurement should be paid attention.
It can be done easily with the optional attenuator.
