A Using Trigger Holdoff to Synchronize Acquisition/Display on Complex Signals
68 Agilent Infiniium 9000 Series Oscilloscope Evaluation Guide
6 Press [AutoScale].
Note that AutoScale
sets up the triggering
and horizontal display
based on the carrier
signal. However, our
desire is to set up the
oscilloscope’s
triggering based on
the envelope of this
complex AM signal.
7 Change time base
setting to 100 µs/div.
Note that the
oscilloscope will
appear to be
untriggered.
8 Press the [Run/Stop]
key.
This will stop
acquisitions and
display the last
acquisition on
screen—the expected
AM signal is now
displayed on a single
acquisition when
stopped. Now let’s set
up the holdoff trigger
value to achieve a
stable trigger.
