Introduction
Random Interleaved Sampling Mode, or RIS is a scope feature available in LeCroy
oscilloscopes. It is an acquisition mode that produces waveforms at very high effective
sample rates. While providing many specific benefits, it is important to understand what
it is and how it works in order to understands the advantages and limitations of this mode
of operation.
RIS mode is selectable from the timebase settings menu when the timebase is set to 20 s
per division or below:
RIS is a special mode that operates differently than traditional acquisition modes and
requires unique understanding to operate properly.
LeCroy scopes will not enter RIS mode unless……
