Digilent Analog Discovery Pro 3000 Benchtop Oscilloscopes

Digilent Analog Discovery Pro 3000 Benchtop Oscilloscopes are portable, high-resolution, mixed-signal, 4-channel (ADP3450) or 2-channel (ADP3250) oscilloscopes offering 14-bit resolution at up to 0.5GS/s. Options are available with and without 4x BNC-to-mini-grabber cables and 2x/4x P2150 oscilloscope probes. The ADP3000 devices feature 16 dedicated digital channels and analog inputs accessible via front panel BNC connectors. With the included digital power supply, digital outputs, 2-channel arbitrary waveform generator, and two dedicated external triggers the Analog Discovery Pro Oscilloscopes come with 12 instruments ready to analyze mixed-signal systems through WaveForms software.

In addition to the 12 built-in instruments enabled by WaveForms, the Analog Discovery Pro 3000 introduces Linux Mode. Linux Mode provides an on-device terminal-based operating system that, when combined with WaveForms SDK, is a flexible starting point for a multitude of custom tests and applications. Running embedded on the device itself or via WaveForms, users can take advantage of data streaming via ethernet, and the on-device storage to capture buffers of millions of samples.

Whether in Linux Mode using WaveForms SDK or in Standard Mode connected via WaveForms, the Analog Discovery Pro 3000 features a variety of advanced triggering options. Instruments within WaveForms can be cross-triggered for example, activating an oscilloscope capture based on a received and decoded digital protocol. External signals can also trigger events using the two dedicated external trigger inputs on the back of the device. WaveForms provides these features configurable in the instruments themselves, or for more control or automation in one of the available scripting interfaces.

WaveForms Instruments Software

WaveForms is the free software application for the ADP3450 and ADP3250 that enables the use of the available analog and digital instruments. The application features a computer and laptop-friendly user interface similar to that of traditional benchtop software. The device communicates with WaveForms via a USB or ethernet connection to your computer, allowing users to capture, record, analyze, and generate mixed-signal and mixed domain waveforms. WaveForms also provides a convenient method for changing between the available modes: Standard Mode and Linux mode.
