Selecting Your Next Oscilloscope: Why Deep Memory Matters


Oscilloscope users consistently rate bandwidth, sample rate, and memory depth as the three most important specifications. Acquisition memory deserves its key specification status next to bandwidth and sample rate. Oscilloscopes with more acquisition memory offer greater flexibility in capturing for longer periods of time, retaining higher sample rates with slower time bases, and offer insurance for both current and future application test and debug needs.

It's helpful to assess the goodness and quality of oscilloscope memory depth, versus just looking at a single figure. Understanding memory depth attributes and benefits ensures selection of a specific oscilloscope matches the desired needs and applications.

When selecting an oscilloscope, compare memory depth claims and understand the settings associated with the claim to make equivalent comparisons. An oscilloscope's ability to quickly process more memory ensures a responsive instrument and higher testing productivity.

This application note will focus oscilloscope selection considerations associated with acquisition memory. Selecting an oscilloscope with deep memory can result in significant troubleshooting and debug time saving.
