Checking trigger status
Check the trigger status from the readout or from the status lights on the Auxiliary Front Panel.
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:
1. A trigger source = Ch3
2. Trigger slope = rising edge
3. Trigger level = 250 mV
4. Time base
5. Check the ARM, READY, and TRIG'D to
determine the trigger status.
6. Check the trigger options menu to
determine the trigger mode.
Check the ARM, READY, and TRIG'D
Auxiliary Front Panel controls to determine the
trigger status.
■
If TRIG'D is on, the instrument has
recognized a valid trigger and is filling the
posttrigger part of the waveform.
■
If READY is on, the instrument can
accept, and is waiting for, a valid trigger
to occur. Pretrigger data has been
acquired.
■
If ARM is on, the trigger circuitry is filling
the pretrigger part of the waveform
record.
■
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 part of the
delayed waveform will fill.
■
If ARM, TRIG'D, and READY are off,
acquisitions have stopped.
