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(bit4):
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 Overview
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 generatea transient trigger:
TRIG:TRAN
Alternatively, if the trigger sourceis BUS, you can also
program a *TRG or an IEEE-488 <get> command.
