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. This input acts 
synchronously. When gated, the output will complete the full pulse width if the output is 
high, and then stop triggering. No pulses are truncated.
