Note

1. X-Y mode waveforms are not stored as reference waveforms.
2. You cannot adjust the horizontal position and scale of the reference waveform.

2.6.4 Using Ref

The reference control saves waveforms to a nonvolatile waveform memory. The
reference function becomes available after a waveform has been saved.
