OPERATING INFORMATION
Delay controls the time interval from the TRIG OUT pulse to the mainframe (PULSE OUT and ECL
OUT) or module outputs. In Single Pulse operation, Delay specifies the interval between the leading
edge of the TRIG OUT signal and the leading edge of the output pulse or impulse (plus a fixed delay
see Figure 1-1).
In Double Pulse operation, Delay determines the leading edge separation between the pair of output
pulses or impulses as well as the interval between TRIG OUT and the second of the two pulses or
impulses.
Width controls the pulse duration of PULSE OUT and ECL OUT (and of the module output) in Pulse
mode. In Impulse Mode, the width is fixed and this setting has no effect.
Single Pulse/Double Pulse determines the number of output pulses or
impulses produced for each trigger. In Single Pulse operation, one delayed pulse or impulse is
generated for each TRIG OUT pulse. In Double Pulse operation, an initial pulse or impulse is produced
at zero Delay as well as a delayed pulse or impulse. The selection of Single or Double Pulse is made
with the {+/-, SGL/DBL} key, which toggles between the two.

{LEVEL} Sequences through the Level parameter menu. The selections are Peak,
Baseline, CW, and External Modulation. All of these are plug-in module
dependent. With no plug-in module these are not available.
Peak Level is used in Pulse Mode. This controls the level of the module output
when PULSE OUT is true (or, for External Drive operation, when the EXTERNAL
DRIVE input is above the External Drive threshold setting).
Baseline Level is the complement of Peak and is also used in Pulse Mode. It
controls the module output level when PULSE OUT is false. For some modules
this setting is not adjustable, and Baseline is set to zero.
External Modulation Level determines the level about which the module output
is modulated in the External Modulation Mode.
CW Level determines the level of the module output in CW Mode.
