Roll Mode
Roll mode displays, in real time, incoming points in single-shot acquisitions
that have a sufficiently low data rate. The oscilloscope rolls the incoming
data continuously across the screen until a trigger event is detected and
the acquisition is complete.
The parameters or math functions connected to each channel are updated
every time the roll mode buffer is updated, as if new data is available. This
resets statistics on every step of Roll mode that is valid because of new
data.
NOTE: If the processing time is greater than the acquire time, the data in memory
gets overwritten. In this case, the instrument issues a Channel data is not
continuous in ROLL mode!!! warning and rolling starts over again.
