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 w aveforms 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 page 67,

Saving waveform data.)

1. Push the RReffront-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 can

not 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 s pace on the screen to display both the reference waveform and the live signal.

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