Front Panel Menu Reference SCPI Command
Select Transient\TrigSource .
To select immediate triggers, select Imm.
To select Bus triggers, select Bus.
To select digital pin 5 as the trigger, select Pin 5, or
EXT.
To select Bus triggers:
TRIG:TRAN:SOUR BUS
To select digital pin 5 as the trigger:
TRIG:TRAN:SOUR PIN5
Initiate the transient 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
Select Transient\Control .
Scroll to Initiate. Then press Select .
To initiate the transient trigger system:
INIT:TRAN
It takes a few milliseconds for the instrument to be ready to receive a trigger signal after receiving the
INITiate:TRANsient command. If a trigger occurs before the trigger system is ready for it, the trigger
will be ignored. You can test the WTG_tran 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 Transient\Control .
The Trig state field indicates "Initiated".
To query the WTG_tran bit (bit 4):
STAT:OPER:COND?
If a bit value of 16 is returned in the query, the WTG_tran bit is true, and the instrument is ready to
receive the trigger signal. Refer to
Status Tutorial .
Unless INITiate:CONTinuous:TRANsient is programmed, the instrument executes
one transient each time a trigger signal is received. Thus, it will be necessary to
initiate the trigger system each time another triggered transient is desired.
Trigger the transient
The trigger system is waiting for a trigger signal in the initiated state. You can immediately trigger the
transient as follows:
Front Panel Menu Reference SCPI Command
Select Transient\Control .
Select Trigger to generate an immediate trigger
signal regardless of the trigger source setting.
To generate a transient trigger:
TRIG:TRAN
Alternatively, if the trigger source is BUS, you can
also program a
*TRG or an IEEE-488 <get>
command.
