Creating Math Waveforms
CSA8000B & TDS8000B User Manual 3- 109
The procedure that follows demonstrates some common operations you can
perform on math waveforms:
Overview To use math waveforms Related control elements & resources
Prerequisites 1. The Math waveform must be defined and displayed. See
the reference listed at right.
See To Define Math Waveforms on page 3--105
Select and dis-
play
2. Press the Vertical MATH button. The button of the
currently displayed and selected math waveform will
light amber; the buttons of all other currently displayed
math waveforms will light green. Math waveforms not
displayed remain unlighted.
3. Press any waveform button to make it the selected
waveform. If the waveform was not displayed,
operation is as follows:
HIf the waveform you select is defined, it displays,
otherwise..
Hthe Define Math dialog box displays so that you
can define and turn on the waveform you just
selected. (See To Define a Math Waveform on
page 3--105 for a procedure for doing so.)
Tip. You can also click the math waveform in the
display, or its icon at the left of the display, to select it.
Set scale and
position
4. Use the Vertical Scale and Position knobs to size and
position the waveform on the screen.
Tip. You can’t adjust the offset of a math waveform.
However, adjustments of offset settings in the source
waveforms will reflect in the math waveform as
determined by its expression.
Tip. You can’t adjust horizontal scale, position, and
sample density (resolution) of math waveforms. If
adjusting these settings affect sources for a math
waveform, the adjustment will be reflected in the math
waveform.
