DELAY Controls. The rotary switch selects one of five
ranges and the vernier provides continuously variable
control of each range. The instrument is set to the
delay indicated on the front panel when the vernier is
in the "MAX" position.

ADVANCE, DELAY, DOUBLE PULSE. With this three position
switch in the ADVANCE position, the leading edge of the
output pulse precedes the leading edge of the SYNC
output. When in the DELAY position, the leading edge of
the SYNC output precedes the leading edge of the main
output. When in the DOUBLE PULSE position, the main
output provides two successive output pulses having a
separation determined by the DELAY (9) controls.
FULSE WIDTH Controls. The rotary switch selects one of
five ranges and the vernier provides continuously
Variable control of each range. The instrument is set
to the pulse width indicated on the front panel when the
vernier is in the "MAX" position.

When operating with pulse widths much greater than 1.0
us, it is necessary to place the internally accessible
DROGP switch in the "ON" position in order to obtain
Pulse top droop of less than SZ. In this position, the
output amplitude will decay very slowly when an attempt
is made to decrease the amplitude. For pulse widths of
less than about 1.0 us, the switch may be in the "OFF"
position and the waveform will exhibit low droop = and
rapid amplitude decay. The unit was shipped with the
switch in the "OFF" position.
POLARITY Switch. If the polarity switch is in the "+"
position, the main output pulse will pulse upwards (i.e.
to a more positive level). If at is in the "-"
position, the output will pulse downwards to a more
negative level.
