Creating and Using Math Waveforms
CSA7000 Series, TDS7000 Series, & TDS6000 Series Instruments User Manual

Use the procedure that follows when defining a spectral math waveform.
Remember, you should first ensure that the sources you use exist. Channel
sources should be acquiring or have acquired data. These sources do not have to
be displayed to be used.
Overview To define a spectral 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 spectral
analysis setup
3. Touch Spectral Analysis Setup, and then select the
Create tab to display the Spectral Analysis Setup control
window.
Select a
spectral
waveform
4. Touch Math(x) and select the math waveform that you
want to create from the list.
5. Touch Magnitude to create a magnitude spectral
waveform, or touch Phase to create a phase spectral
waveform.
6. Touch the channel number that contains input data for
the spectral analyzer.
7. If you want an averaged spectral waveform, touch
Average, touch Avgs, and then set the number of
averages in the control window.
Note. If you want to redefine your waveform, touch the
Clear button and repeat the above steps.
