Note: if the analog channel or the math function is clipped (waveforms are not
completely displayed on the screen), then the resulting math will also be clipped.
To Make a Math Operation
The oscilloscope supports many math operations between analog channels including
addition (+), subtraction (-), multiplication (*), division (/), FFT, differential (d/dt), integral
(∫dt), square root (√). The resulting math waveform is displayed in white and labelled with
“M”. You can use cursors to measure it.
