Note: if the analog channel or the math function is cut off (waveforms do not display on
the screen completely), the resulting math will also be cut off.
To clear the appointed reference waveform, you can save a new reference waveform to
the same location to cover it.
To Make Math Operation
The oscilloscope supports many math operations between analog channels and reference
waveforms, including addition (+), subtraction (-), multiplication (*), division (/),
FFT,differential (d/dt), integral (∫dt), square root (√). The resulting math waveform is
displayed in white and labeled with “M”. You can use cursors to measure it.

Units for Math Waveforms
Use the channel function menu to set the unit of each channel to “V” or “A”. The
oscilloscope math operation includes units as below:
