As before, if the delay is negative, the order of the SYNC and OUT pulses is reversed.
TRIGGER MODES
This instrument has four trigger modes:
Internal Trigger: the instrument controls the trigger frequency, and generates the
clock internally.
External Trigger: the instrument is triggered by an external TTL-level clock on the
back-panel TRIG connector.
Manual Trigger: the instrument is triggered by the front-panel “SINGLE PULSE”
pushbutton.
Hold Trigger: the instrument is set to not trigger at all.
These modes can be selected using the front panel trigger menu, or by using the
appropriate programming commands. (See the “Programming Manual for -B
Instruments” for more details.)
GATING MODES
Triggering can be suppressed by a TTL-level signal on the rear-panel GATE connector.
The instrument can be set to stop triggering when this input high or low, using the front-
panel gate menu or the appropriate programming commands. When gated, the output
