Enables the operator to set the desired delay between TRIG
OUTPUT pulse and HP 8112A OUTPUT pulse.
When selected, double pulses are output, their characteristics being
defined by the parameter settings. The width of each pulse is either
equal to the WID setting or half the DTY setting. The range of
delay between the two pulses is 20 ns to 950 ms.
Enables pulse width to be set between 10 ns and 950 ms.
Pulse duty cycle is variable from 1% to 99%. Percentage values are
shown on the digital display.
These two keys are used in conjunction with TRANSITION MODE
keys. It is possible to increase or decrease rise and fall times of
output pulses. Should you select a rise or fall time which degrades
the HIL or LOL settings, an
above the two keys and the key associated with the incompatible
parameter will flash.
When either of these keys is selected, the corresponding level may be
set.
The selected HIL value is inoperative in the HILC mode.
This key causes the HP 8112A to assume a factory programmed
parameter set as follows:
NORM Active

PER

Active
WID 50% of PER
LEE 10% of PER
TRE 10% of PER
SET is automatically eliminated by selection of any other mode or
parameter key or by pressing PER again.
