WARNING: The output stage may be damaged if triggered by an external signal at a
pulse repetition frequency greater than 20 kHz.

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
will complete the full pulse width if the output is high, and then stop triggering. Pulses
are not truncated.
