Measurements and Math Functions
Add or Subtract
228
When you select add or subtract, the Source 1 and Source 2 channel voltage values are
added or subtracted point by point, and the result is displayed.
You can use subtract to make a differential measurement or to compare two waveforms.
If your waveforms' DC offsets are larger than the dynamic range of the oscilloscope's
input channels you will need to use a differential probe instead.
Example: Subtract channel 2 from channel 1
•
Scale — lets you set your own vertical scale factors for subtract, expressed as
V/div (Volts/division) or A/div (Amps/division). Press the Scale softkey, then turn
the Entry knob to rescale. Units are set in the channel Probe Menu.
•
Offset — lets you set your own offset for the math function. The offset value is in
Volts or Amps and is represented by the center horizontal grid line of the display.
Press the Offset softkey, then turn the Entry knob to change the offset of the math
waveform.
A scale unit of U (undefined) will be displayed for scale and offset if the two source
channels are set to dissimilar units. Units are set using the channel's Probe Units
softkey.
