Key Points
VOLTS/DIV. Use the VOLTS/DIV control to scale the waveforms of
the channels. The math waveform is the visual sum or difference of
the channel waveforms.
Channel Display for a TDS 210 or TDS 220 (Firmware Below V 2.00).
Displaying a math waveform automatically removes the display of
channels used to create the math waveform. Math operations are
turned off if a channel used in the operation is turned on.
NOTE. You can push the menu box button of the enabled math
operation on a TDS 210 or TDS 220 to switch between the math
waveform and the channels used to create the math waveform.
