Using Mathematics Functions +, -, x, XY-mode
You can add (+), subtract (-), or multiply (x) two
waveforms. The test tool will display the mathematical
result waveform and the source waveforms.
The XY-mode provides a plot with one input on the vertical
axis and the second input on the horizontal axis.
The Mathematics functions perform a point-to-point
operation on the involved waveforms.
To use a Mathematics function, do the following:
1
SCOPE
Display the SCOPE key labels.
2 F4 Open the WAVEFORM OPTIONS menu.
3
ENTER
Jump to Waveform: and Select
Mathematics... to open the
Mathematics menu.
4
ENTER
Select Function: +, -, x or XY-
mode.
5
ENTER
Select the first waveform:
Source 1: A, B, C or D
6
ENTER
Select the second waveform:
Source 2: A, B, C or D
The mathematical function key
labels will be displayed now:
7 F2
F3
F4
Press to select a scale
factor to fit the result waveform
onto the display.
Press
to move the result
waveform up or down.
Switch the result waveform on/off
(toggle).
The sensitivity range of the mathematical result is equal to
the sensitivity range of the least sensitive input divided by
the scale factor.
