The Digital Discovery is a combined logic analyzer and pattern generator instrument designed to allow you to debug, visualize, and simulate digital signals for most embedded projects. The High Speed Adapter and impedance-matched probes can be paired with the Digital Discovery to measure up to 800 MS/s with the logic analyzer.
The following materials are used with this tutorial:
The high speed adapter with twisted wires provides proper termination, improved bandwidth, and noise reduction to enable Digital Discovery to take higher resolution measurements. This is highly recommended for observing high speed signals exceeding 100 MHz or to look at signal phase with better than 10 ns of resolution.
In the WaveForms software, a selection of high-speed pin groups are available to choose from in the upper right-hand corner of the WaveForms GUI. Currently, only these pins can be chosen for high speed inputs.
The Digital Discovery with the High-Speed Adapter can be further explored by following the Decoding VGA Signals With a Portable Logic Analyzer project.
