please refer to “Chapter 3 Horizontal System” and “Chapter 4 Vertical System”.
3) The vertical sensitivity, unit and time base corresponding to the math waveform are displayed in the channel
area of the math channel. For details, see “2.6 Understand the Oscilloscope Display Interface”.
Math waveform units
Use “Probe Type” on the channel menu to adjust the channel unit (refer to “4.4.4 Set Probe Type”) and set the
unit of each input channel to Volt or Ampere. The units of math function waveform include:
Table 8-1 List of Mathematical Units
Note: If the units of two operation source channels are different and the unit combination cannot be identified, the unit of
math function will be displayed as? (undefined).
Math operators
Math operators perform arithmetic operations on the analog input channels.
Addition or subtraction
If addition or subtraction is selected, the values of function sources 1 and 2 will be added or subtracted point by
point and the results will be displayed.
