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?
If bit 3 is set in the query response, the WTG_meas bit is true, and the instrument is ready to receive
the trigger signal. Refer to
Status Tutorial for more information.
The instrument executes one measurement acquisition each time a bus, pin,
transient, or level trigger command is received. Thus, it will be necessary to initiate
the trigger system each time a triggered measurement is desired.
Trigger the Measurement
The trigger system is waiting for a trigger signal in the initiated state. You can immediately trigger the
measurement as follows:
Front Panel Menu Reference SCPI Command
Not available To generate a measurement trigger:
TRIG:ACQ
Alternatively, if the trigger source is BUS, you can also
program a
*TRG or an IEEE-488 <get> command.
As previously discussed, a trigger can also be generated by a digital pin or a trigger out signal
(transient). If a digital pin is configured as the trigger source, the instrument will wait indefinitely for the
trigger signal. If the trigger does not occur, you must manually return the trigger system to the idle
state. The following commands return the trigger system to the idle state:
Front Panel Menu Reference SCPI Command
Select Measure\Control .
Then select the Abort control.
ABOR:ACQ
Fetch the measurement
After a trigger is received and the measurement completes, the trigger system will return to the idle
state. Once the measurement completes, FETCh queries can retrieve the most recent measurement
data without initiating a new measurement or altering the data in the measurement buffer.
