The delay, pulse width, and frequency (when in the internal mode), of the OUT pulse 
can be varied with front panel controls or via the GPIB or RS-232 computer interfaces.

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.)
