Scaling and Positioning a Reference Waveform You can position and
scale a reference waveform independenty from all other displayed
waveforms. Select the reference waveform and then adjust it with a
vertical or horizontal POSITION or SCALE control. You can do this
whether acquisition is running or is stopped.
If a reference waveform is selected, scaling and repositioning of the
reference waveform operates the same way whether zoom is turned
on or off.
Gray-Scale Restriction. Reference waveforms are always saved from
the most current acquisition and do not contain any gray-scale
information.
