Analog Discovery 2 (410-321)

Description

Digilent Analog Discovery 2, developed in conjunction with Analog Devices and supported by Xilinx University Program, is a multi-function instrument that allows users to measure, visualize, generate, record, and control mixed signal circuits of all kinds. The low-cost Analog Discovery 2 is small enough to fit in your pocket, but powerful enough to replace a stack of lab equipment, providing engineering students, hobbyists, and electronics enthusiasts the freedom to work with analog and digital circuits in virtually any environment, in or out of the lab. The analog and digital inputs and outputs can be connected to a circuit using simple wire probes; alternatively, the Analog Discovery BNC Adapter and BNC probes can be used to connect and utilize the inputs and outputs. Driven by the free WaveForms 2015 (Mac, Linux and Windows Compatible) software, Analog Discovery 2 can be configured to work as any one of several traditional instruments.

The Analog Discovery 2 was designed for students in typical university-based circuits and electronics classes. Its features and specifications, as well as the additional requirements of operating from USB or external power, maintaining the small and portable form factor, the robustness to withstand student use in a variety of environments, and low-cost are based directly on feedback that was obtained from numerous professors from several universities. Meeting all of these requirements proved challenging; however, the task ultimately generated some new and innovative circuits. This document describes the Analog Discovery 2's circuits, with the intent of providing a better understanding of its electrical functions, operations, and a more detailed description of the hardware’s features and limitations. It is not intended to provide enough information to enable complete duplication of the Analog Discovery 2, or to allow users to design custom configurations for programmable parts in the design.
