RIS Sampling Mode - For Higher Sampling Rates

RIS (Random Interleaved Sampling) is an acquisition technique that allows
effective sampling rates higher than the maximum single-shot sampling
rate. It is used on repetitive waveforms with a stable trigger. The maximum
effective RIS sampling rate is achieved by making multiple single-shot
acquisitions at maximum real-time sample rate. The bins thus acquired are
positioned approximately 5 ps (200 GS/s) apart. The process of acquiring
these bins and satisfying the time constraint is a random one. The relative
