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.
Connect a signal to the oscilloscope.
1
Set the trigger level to the middle of the waveform.
2
Adjust the Holdoff knob to synchronize the trigger of the
3
oscilloscope with the complex waveform.
