Creating and Using Math Waveforms
3- 194
CSA7000 Series, TDS7000 Series, & TDS6000 Series Instruments User Manual
Use the procedure that follows when defining a math waveform. Remember, you
should first ensure that the sources you use exist. Acquisitions should be running
or the channels should already be on, and reference waveform sources should
contain saved waveforms, and so on. These sources do not have to be displayed
to be used.
Overview To define a math waveform Related control elements and resources
Prerequisites
1. All channel and reference Waveforms and automatic
measurement scalars t hat you will use in your math
waveform must be available (channels and references
contain data, measurement scalars are defined, and so
on).
See page page 3--34 for acquisition setup and page 3--71
for trigger setup.
Display the
math control
window
2. From the toolbar, touch the Math button to display the
Define Math control window.
Select a math
waveform
3. Select the Math(x) tab for the math waveform that you
want to define. Be sure to touch Display to toggle it on,
so that the waveform displays.
If the waveform that you select already exists, its math
expression appears in the window. You can still use t he
waveform by touching the Clear button, which discards
its previous math expression. Or repeat step 3 to select
another waveform.

4. Touch one of the Predefined Expression buttons to use
a predefined math expression, or touch Editor to
Define/Edit a new math expression.
