Display Waveform Data
Quick Tips
Variable persistence accumulates record points for a speci fi ed time interval. Each record point decays independently according
to the time interval. Use variable persistence for displaying infrequently appearing signal anomalies, such as glitches.
In fi nite persistence continuously accumulates record points until you change one of the acquisition display settings. Use in fi nite
persistence for displaying unique signal anomalies, such as glitches.
The XY Display mode graphs the data in fi xed pairs of waveforms against one another. You can use CH1 versus CH2, and
REF1 versus REF2. On four-channel models, you can also use CH3 versus CH4, and REF3 versus REF4.
When the XY Display is on, an upper window appears that displays data versus time.
