Add a math, reference, or bus waveform
Math waveforms let you create new waveforms based on operations between two or more waveforms or by applying equations to
waveform data. A reference waveform is a static waveform record displayed for comparison. Bus waveforms let you view and analyze
serial or parallel data.
There is no set limit to the number of Math, Reference, or Bus waveforms you can add to the W
aveform View, other than system physical
memory constraints.
1. Tap the Add New Math, Add New Ref, or Add New Bus button in the Settings bar.
2. The instrument adds the waveform to the W
aveform view, adds a Waveform badge to the Settings bar, and opens a configuration
menu. This example shows adding a Math waveform.
3. Use the configuration menus to refine the waveform parameters. Displayed fields depend on the waveform and selections made in the
menu. Selection changes take ef
fect immediately.
This example shows adding a Math waveform, using the Math Source fields to select Ch 1 and Ch 2 as the waveform sources, set the
math type to Basic math operation, and subtracting channel 2 from channel 1.
4. When adding a Reference waveform, the instrument displays a Recall configuration menu. Navigate to and select the reference
waveform file (*.wfm) to recall, then tap the Recall button. The instrument displays the Reference waveform.
5. Double-tap a math, reference, or bus badge to check or change the waveform settings.
See Configure channel or waveform
settings on page 47.
6. Tap the Help icon on a configuration menu title for more information on math, reference, and bus waveform settings.
7. Tap outside the menu to close the menu.
