General Information
The Type 109 Pulse Generator produces fast rising pulses
at a repetition rate between 550 and 720 cycles per second.
The risetime of the pulses is less than 0.25 nanosecond, the
polarity can be selected, and both the amplitude and dura­
tion are variable.
The Type 109 is intended for use with fast rise sampling
(equivalent-time) systems or conventional (real-time) oscillo­
scopes.
The Type 109 is fully transistorized, except for a VR tube,
and requires no warmup time before operating. As soon
as the POWER O N switch is turned on, the Type 109 is
ready to operate.

Power Requirements
The Type 109 can be operated from either 117 or 234
volts nominal. The only changes necessary to convert from
one operating voltage to another are in the wiring of the
power transformer primary. The power transformer, T601,
has two separate primary windings. The windings are con­
nected in parallel for 117-volt operation and in series for
234-volt operation.
A small metal tag located near the power receptacle at
the rear of the instrument indicates the nominal line voltage
for which the Type 109 was wired at the factory. If wired
for 117 volts, the instrument will operate properly with
