PSPL2600C Pulse Generator Datasheet
The PSPL2600C Pulse Generators provide high amplitude positive or negative pulses with convenient front panel control. The output has fast edge rates, smooth transitions and minimal overshoot and ringing. Adjustable output levels are obtained using internal step attenuators, ensuring consistent signal shape at all settings. The outputs are designed for a 50 Ω impedance, but can safely drive any load from a short circuit to an open.
