Persistence mode
Persistence mode superimposes multiple waveforms on the same view, with more
frequent data or newer waveforms drawn in brighter colors than older ones. This is
useful for spotting glitches, when you need to see a rare fault event hidden in a series
of repeated normal events.
Enable persistence mode by clicking the Persistence Mode button on the
Capture Setup toolbar. With the persistence options set at their default values, the
screen will look something like this:
The colors indicate the frequency of the data. Red is used for the highest-frequency
data, with yellow for intermediate frequencies and blue for the least frequent data. In
the example above, the waveform spends most of its time in the red region, but noise
causes it to wander occasionally into the blue and yellow regions. These are the
default colors, but you can change them using the Persistence Options dialog.
This example shows persistence mode in its most basic form. See the Persistence
Options dialog for ways to modify the display to suit your application, and How to
find a glitch using persistence mode for a worked example.
