The GFT500 module is an externally triggered fast leading edge step generator. This compact module produces step pulses of 5 V under 50 Ω, with fast 200 ps rise time.
The output amplitude and width is factory adjustable between 4 V to 9 V and 50 ns to 1 µs.
The GFT500 can be used with a delay generator to generate a very fast rise time.
