2 Quick Reference
Math Waveforms
Math functions can be performed on analog channels and lower math functions.
The resulting math waveform is displayed in light purple.

Math Operating Hints
If the analog channel or math function is clipped (not fully displayed on screen) the resulting
displayed math function will also be clipped.
Once the function is displayed, the analog channel(s) may be turned off for better viewing of
the math waveform.
The math function waveform can be measured using [Cursors] and/or [Meas].
