The Model 507 High Current Pulse Generator is an ideal fire set for airbag squib, detonator, and pyrotechnics initiator testing. The instrument provides adjustable current signals up to 25 amps. The unit comes with 2 or 4 digitally controlled load resistant independent outputs. Output pulse widths and delays are unique to each channel and can be precisely controlled from 0.1 to 100 msec in 200 ns steps. The Current Pulse Generator also provides a TTL Sync output to T0 – particularly useful as a reference source/trigger for cameras or other equipment. Applications such as air bag deployment testing (squib detonation), igniter triggering, or ballistics work can be done reliably, safely, and with a high level of repeatability.
