As previously discussed, a trigger can also be generated by a digital pin, an output transient, and an
output voltage or current level. 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
Select Measure\Control.
Then select the Abort control.
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.
Front Panel Menu Reference
Not available
If a FETCh query is sent before the measurement is finished, the response will be delayed until the
measurement trigger occurs and the acquisition completes. To prevent this from occurring, you can
poll the MEAS_active bit after the measurement is initiated to determine when the measurement is
complete and then send the FETCh query.
You can test the MEAS_active bit in the operation status register to know when the trigger system has
returned to the idle state.
