Transient<n> - Selects the output channel’s transient system as the trigger source. <n> specifies the
channel. When you select a channel, you must also set up that channel’s transient system to
generate a trigger out signal. See Generate Trigger Out Signals and Program an Arbitrary List.
Use the following commands to select a trigger source:
Front Panel Menu Reference SCPI Command
Not available To selectBus triggers for output 1:
TRIG:ACQ:SOUR BUS, (@1)
To selecta Digital pin as the trigger:
TRIG:ACQ:SOUR PIN<n>, (@1)
To selecta Transient output as trigger:
TRIG:ACQ:SOUR TRAN<n>, (@1)
where n is the output channel that will generate the
trigger signal.
Initiate the Measurement Trigger System
Next, you must initiate or enable the measurement trigger system.
When the power system 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. To initiate the trigger system, use:
Front Panel Menu Reference SCPI Command
Not available To initiatethe measurement trigger system:
INIT:ACQ (@1)
It takes a few milliseconds for the instrument to be ready to receive a trigger signal after receiving the
INITiate:ACQuire command, and it can take longer for Keysight Models N678xA SMU.
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
Not available To query the WTG_meas bit (bit 3):
STAT:OPER:COND?(@1)
If a bit value of 8 is returned in the query, the WTG_meas bit is true, and the instrument is ready to
receive the trigger signal. Refer to Status Tutorial for more information.
It will be necessary to initiate the measurement trigger system each time a triggered
measurement is desired.
