Note
Enables the operator to set the desired delay between TRIG
OUTPUT pulse and HP 8 1 12A 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 HI1 or 101 settings, an
EXCESSIVE
message will illuminate
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 HI1 value is inoperative in the HI1C mode.
