Information

The Model 212A Pulse Generator is a fundamental measuring instrument for determining the action of circuits under conditions of rapid change. The pulse produced by this instrument has a short time of rise-and decay with a flat top and minimum of overshoot. Either positive or negative pulses are available and the pulse shape is independent of the repetition rate, connected load, sync condition, supply voltages, and output attenuator setting. The pulse length is continuously variable from . 07 to 10 microseconds. This instrument is applicable to the testing of radar systems, nuclear counting circuits, television systems, response of video amplifiers, filters and band pass circuits and pulse modulation of UHF signal generators.
