Digilent Digital Discovery: USB Logic Analyzer and Digital Pattern Generator

Features and Specifications

• 32-channel digital logic analyzer (1.2-3.3V CMOS, 8 channels at 800 MS/s*, 16 channels at 400 MS/s*, and 32 channels at 200 MS/s)
• 11 Built in Interpreters, Custom Interpreters available via scripting
• Protocol Analyzer Featuring Digital Bus Analyzers (SPI, I2C, UART, CAN, AVR)
• 16-channel pattern generator (1.2-3.3 V CMOS, 100 MS/s)
• 16-channel virtual digital I/O including buttons, switches, and LEDs – perfect for logic training applications
• 4-channel programmable power supply of 1.2-3.3 V /100 mA. The same voltage supplies the Logic Analyzer input buffers and the Pattern Generator input/output buffers, for keeping the logic level compatibility with the circuit under test.
• All Inputs and Outputs Programmable
• Selectable Digital IO pulls
• Selectable Drive, Slew, Pull and Frequency
• Logic Level Selectable between 1.2 V and 3.3 V

*Note: to ensure signal integrity on speeds of 200 MS/s and higher, the High Speed Adapter and Logic Probes must be used.

Digital Discovery Overview

The Digilent Digital Discovery is a portable multifunctional tool, serving as a logic analyzer, protocol analyzer, and pattern generator. It was designed to be the perfect companion for embedded development, compatible with a broad range of digital systems. The design of the Digital Discovery prioritizes channel optimization, speed, and portability. Its compact size makes it easy to store and it comes with a comprehensive set of advanced features that enable debugging, visualization, and simulation of digital signals for a majority of embedded projects.

It was designed to be a flexible logic analyzer with the ability to be reconfigured as needed at the touch of a button. Test one design with all 32 channels at 3.3 V, then switch to another design requiring the maximum sample rate at the full 800 MS/s and any other logic level between 1.2 V and 3.3 V, all with the same device.

Digital inputs and outputs can be connected to a circuit using simple wire probes or breadboard wires; alternatively, the Digital Discovery High-Speed Adapter and impedance-matched probes can be used ensure signal integrity on higher speed signals.

The Digital Discovery is tailored for those venturing into embedded development. Its features and specifications are carefully selected to ensure a compact and portable design, capable of withstanding use in various environments. All these features are powered by complimentary software, WaveForms.
