BK Precision 2194 - Math; Units for Math Waveforms

Math
The oscilloscope supports many math operations between analog channels including addition (+), subtraction (-),
multiplication (*), division (/), FFT, dierential (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.
Note:
If the analog channel or the math function is cut o (waveforms do not display on the screen completely), the resulting
math will also be cut o.
9.1 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:
