Engineers need the ability to acquire and analyze very long time windows with 20 million points or more to identify the source of problems. Similarly long record capture and analysis is required in spread spectrum clocking (SSC) applications used to reduce EMI emissions.

The latest high-bandwidth digital oscilloscopes offer deep waveform memory configurations — up to 250 million (250M) samples per channel. These instruments can store many repetitions of patterns such as CJPAT and PRBS15-1.
Still all oscilloscopes have a finite amount of memory depth, and using higher sample rates fills the instrument's memory more rapidly and decreases the time window of data acquisition.
We look at different tools to improve the efficiency of managing and analyzing long time windows and large data acquisitions.
