Trigger Source Description
Bus Selects GPIB device trigger, *TRG, or <GET> (Group Execute Trigger).
Current Selects an output current level.
External Selects ANY pin that has been configured as a Trigger Input on the digital control
port.
Pin<1-7> Selects a specific pin<n> that is configured as a Trigger Input on the digital con-
trol port.
Transient Selects the unit’s transient system. You must also set up the transient system to
generate a trigger out signal. See
Programming Output Transients .
Voltage Selects an output voltage level.
Use the following commands to select a trigger source:
Front Panel Menu Reference SCPI Command
Not available To select Bus triggers:
TRIG:TRAN:SOUR BUS
To select digital pin 5 as the trigger:
TRIG:ACQ:SOUR PIN5
To select a voltage or current level:
TRIG:ACQ:SOUR VOLT
TRIG:ACQ:SOUR CURR
To select an output transient as trigger:
TRIG:ACQ:SOUR TRAN
Initiate the acquisition system
When the unit is turned on, the trigger system is in the idle state. In this state, the trigger system is
disabled, ignoring all triggers. The INITiate commands enable the trigger system to receive triggers.
Front Panel Menu Reference SCPI Command
Not available To initiate the measurement trigger system:
INIT:ACQ
It takes a few milliseconds for the instrument to be ready to receive a trigger signal after receiving the
INITiate:ACQuire command. If a trigger occurs before the trigger system is ready for it, the trigger will
be ignored. You can test the WTG_meas bit in the operation status register to know when the
instrument is ready to receive a trigger after being initiated.
Front Panel Menu Reference SCPI Command
Select Measure\Control .
The Trig state field indicates "Initiated".
To query the WTG_meas bit (bit 3):
STAT:OPER:COND?
