HP 54645A - To Trigger on a Complex Waveform

To trigger on a complex waveform
The difficulty in viewing a complex waveform is triggering on the signal. The
simplest trigger method is to trigger the oscilloscope on a sync pulse that is
associated with the waveform. If there is no sync pulse, use these steps to
trigger on a periodic complex waveform.
1
Connect a signal to the oscilloscope.
2
Set the trigger level to the middle of the waveform.
3
Adjust the Holdoff knob to synchronize the trigger of the
oscilloscope with the complex waveform.
