Creating Math Waveforms
CSA8000B & TDS8000B User Manual

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 l isted at right.
See To Define Math Waveforms on page3--105
Select and di s-
play
2. Press t he Vertical MATH button. The button of the
currently displayed and selected math waveform wil l
light amber; the buttons of all other currently displayed
math waveforms wi ll light green. Math waveforms not
displayed remain unl ighted.
3. Press any waveform button to make it the selected
waveform. If the waveform was not displayed,
operation is as follows:
H If the wavef orm you select i s defined, it displ ays,
otherwise..
H the Define Math dialog box displ ays so that you
can define and turn on the wavef orm you just
selected. (See To Define a Math Waveform on
page 3--105 for a procedure for doing so.)
Tip. You can also click t he math waveform i n 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 wavef orm.
However, adjustments of offset settings in the source
waveforms will reflect in the math waveform as
determined by it s expression.
Tip. You can’t adjust horizontal scale, position, and
sample density (resoluti on) of mat h waveforms. If
adjusting these set tings affect sources for a math
waveform, the adjustment wil l be refl ected in the math
waveform.
