Descrizione: Pulse Generator
Informazioni:
                                    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.
