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.)
