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. This input can also be set
to act synchronously or asynchronously. When set to asynchronous mode, the GATE
will disable the output immediately. Output pulses may be truncated. When set to
synchronous mode, the output will complete the full pulse width if the output is high,
and then stop triggering. No pulses are truncated in this mode.
