Analyze Waveform Data
The square and circle shapes in the readout map to the multipurpose knobs when both vertical and horizontal cursors are present.
Using XY Cursors
When the XY Display mode is on, the cursor readouts will appear to the right of the lower graticule (XY). They will include rectangular,
polar, product, and ratio readouts. The oscilloscope will display vertical-bar waveform cursors in the upper graticule (YT).
Using Math Waveforms
Create math waveforms to support the analysis of your channel and reference waveforms. By combining and transforming source
waveforms and other data into math waveforms, you can derive the data view that your application requires.
NOTE. Math waveforms are not available for use with serial buses.
Use the following procedure for executing simple (+, –, *, ÷) math operations on two waveforms:
