Operating Basics
Checking Trigger Status
You can check the trigger status from the status lights on the front panel or from the acquisition readout.
Check the ARM, READY, and TRIG’D
front-panel controls to determine the
trigger status.
H
If TRIG’D is on, the instrument
has recognized a valid trigger and
is filling the posttrigger portion of
the waveform.
H
If READY is on, the instrument
can accept, and is waiting for, a
valid trigger to occur. Pretrigger
data has been acquired.
H
If ARM is on, the trigger circuitry
is filling the pretrigger portion of
the waveform record.
H
If both TRIG’D and READY are on,
a valid A event trigger has been
recognized and the instrument is
waiting for a delayed trigger.
When a delayed trigger is
recognized, the posttrigger
portion of the delayed waveform
will fill.
H
If ARM, TRIG’D, and READY are
off, acquisitions have stopped.
To quickly determine the settings of
some key trigger parameters, check
the Trigger readout at the bottom of
the display. The readouts differ for
edge and the advanced triggers.
