Analyzing a waveform

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

les. (See page 67,

Saving waveform data

Push the

R Ref

front-panel button.

Push the

Ref1

Ref2

side-menu button to toggle displaying that waveform

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.
