A New Pulse Generator
with Very Fast Rise Time
'~T~1HE development of faster and faster cir- signal level of 10 volts across 50 ohms and at
JL cuitry in computer and other work is heav repetition rates of up to 1 megacycle. Despite
ily dependent on the availability of means for its high speed, the instrument is a true general-
generating and displaying the fast waveforms purpose generator with selectable pulse polar
that such circuits employ. One tool that has ity, a calibrated pulse width control, pulse base
been of great importance line set at ground, an output attenuator control,
