Analog Discovery 3 Digilent USB Oscilloscope with Waveform Generator

Description

Product Overview

The Analog Discovery 3 is a compact, USB‑powered test platform that brings together four essential instruments in one sleek enclosure. At its core is a 125 MS/s, 14‑bit resolution oscilloscope capable of capturing fast transients with a ±25 V input range and a bandwidth exceeding 30 MHz when equipped with the optional BNC adapter. Complementing the scope is a two‑channel arbitrary waveform generator that delivers 14‑bit resolution at up to 125 MS/s, supporting a ±5 V output range and a 12 MHz bandwidth, making it suitable for generating precise analog signals, modulation schemes, and custom waveforms.

Beyond analog measurement, the device incorporates a 16‑channel logic analyzer and pattern generator. Each digital I/O line can be configured independently for 3.3 V logic levels, with 5 V tolerant inputs, enabling high‑speed serial protocol analysis such as SPI, I²C, UART, CAN, and JTAG. The logic engine samples at 125 MS/s, providing deep insight into digital communication and timing relationships within complex embedded systems.

Power delivery is handled by two programmable supplies that can source up to 800 mA per channel when paired with an auxiliary power source. The supplies cover a bipolar range from –5 V to +5 V with 0.5 V resolution, allowing designers to bias circuits, test power‑up sequences, and emulate a variety of supply conditions without external equipment.

All of these capabilities are accessed through Digilent’s intuitive software suite, which includes a suite of virtual instruments such as a spectrum analyzer, network analyzer, impedance analyzer, and protocol analyzer. The platform also offers in‑app scripting, data logging, and integration with popular development environments like LabVIEW, MATLAB, Python, C, and C++. A one‑year subscription to Multisim Live and a 30‑day trial of EveryMeasure are included, providing immediate access to simulation and collaboration tools.

Physically, the Analog Discovery 3 measures just 7 × 2 × 9 inches and weighs under 9 oz, making it ideal for desktop workstations, field service kits, or classroom labs. It ships with a plastic project box, USB‑C programming cable, flywire signal cables, header kits, and labeling accessories, ensuring users have everything needed to start experimenting right out of the box.

Usage

Engineers designing mixed‑signal PCBs can use the Analog Discovery 3 to validate both analog waveforms and digital communication on a single device, reducing the need for multiple bench instruments and speeding up the debug cycle. In educational settings, instructors can demonstrate fundamental concepts such as signal generation, Fourier analysis, and protocol decoding, while students gain hands‑on experience with real‑world measurement tools.

Hobbyists building Arduino‑compatible projects, robotics, or IoT devices benefit from the ability to generate custom waveforms, monitor power consumption, and capture high‑speed digital signals without leaving the workbench. The portable nature of the device also makes it a perfect companion for field technicians who need to troubleshoot equipment on site, offering a full suite of analysis tools in a lightweight package.

Researchers developing novel sensor interfaces or low‑power communication schemes can leverage the programmable power supplies and high‑resolution data acquisition to characterize performance under varying voltage conditions. The integrated SDKs enable automated testing, batch data collection, and custom algorithm development, facilitating reproducible experiments and rapid iteration.

Because the platform is USB‑C powered, it can be operated from a laptop, desktop, or even a power bank, providing flexibility for mobile labs, remote deployments, or constrained environments where traditional bench power is unavailable.

FAQ

What operating systems are supported?

The Digilent WaveForms software runs on Windows 10/11, macOS 10.13 or later, and major Linux distributions. Compatibility with the latest USB‑C drivers is required for optimal performance.

Can I use the device without an external power source?

Yes, the Analog Discovery 3 can be powered directly from a USB‑C port, but the programmable power supplies require an auxiliary power source to deliver the full 800 mA per channel.

Is the device suitable for high‑frequency RF work?

While the oscilloscope offers a 30 MHz bandwidth (up to 100 MHz with the BNC adapter), it is not intended for deep RF analysis. For RF applications, a dedicated RF scope is recommended.

How does the licensing work for the included software?

The package includes a one‑year Multisim Live subscription and a 30‑day trial of EveryMeasure with 5 GB storage and up to 5 users. After the trial, you may purchase additional licenses directly from Digilent.

What warranty and support are provided?

All Analog Discovery 3 units come with a standard one‑year limited warranty covering manufacturing defects. Technical support is available via email and the Digilent community forums.
