Displaying reference waveforms
A reference waveform is a waveform that you have stored in a nonvolatile
memory location on the oscilloscope. You can use a reference waveform as a
standard against which to compare other waveforms.
You can save channel, math, and FFT waveforms to reference memory.
Reference waveforms remain in memory when the oscilloscope is powered off.
See the Saving waveform data topic to learn how to save waveforms to reference
memory or external files. See Saving waveform data on page 126.
1. Push the Ref front-panel button.
2. Push the Ref1 or Ref2 side-menu button to toggle displaying that waveform
On or Off.
You can display both reference waveforms at the same time.
Reference waveform tips
■
You cannot position or scale a reference waveform. You should set the
source waveform position and scale before saving to a reference location, so
that you have space on the screen to display both the reference waveform and
the live signal.

You can use Zoom to show more detail on reference waveforms.
