Configure Trigger Source
The trigger function is used to initiate the start of a program in list mode and also as a toggle for
transient mode. The trigger source can be set so that users can send a trigger from the front
panel, through a remote command via remote interface or through the external trigger input in
the rear panel. Follow the steps below to configure the trigger mode:
1. From the SYSTEM menu, browse and select Trigger and press .
2. Here are the options:
Manual(Def) – Manual trigger. Front panel trigger button is used to send a trigger
(press and (or press ) to send trigger).
External – External trigger. Trigger can be sent by connecting the Trig input and the
ground input together in the rear panel. A TTL signal may also be used as a trigger signal
when sent across these terminals. If using a TTL signal, the unit triggers off of a falling
edge.
NOTE:
Signal pulse width must be > 10 µs.
Hold – Hold trigger. This behaves similarly to Bus trigger, however the TRIG:IMM
command is used instead.
Bus – Bus trigger. Remote commands *TRG and TRIG:IMM can both be used to send a
trigger. With Bus trigger, multiple devices can be triggered at the same time when
communicating via GPIB interface.
Timer – Timer trigger. A trigger will be sent periodically based on the set time. Time
can be set from 0.01 s to 9999.99 s.
3. Select one of the options. For timer trigger, use the numeric keypad or rotary knob to
set the time.
