Discover More with the New Analog Discovery 3

Digilent’s latest multi-function test and measurement device, also known as the AD3, is a digital oscilloscope, logic analyzer, waveform generator, pattern generator, and much more. Using the flexible WaveForms software (supported by Windows, Mac, and Linux), the Analog Discovery 3 can be used in the lab, in the field, or even at home - you're no longer tied down to a traditional benchtop and stacks of expensive test instruments.


Like its predecessor, the Analog Discovery 3 is a portable USB-powered test and measurement device, though it now features an upgraded USB-C® connection. It’s lightweight and small enough to fit in your pocket or backpack, so it becomes an exceptional companion for any engineer.

Expanded WaveForms Features

The Analog Discovery 3 boasts a larger-than-ever buffer size, allowing more data to be sent through the waveform generator and received through the mixed signal (analog and digital) oscilloscope. It also has an increased sampling rate of up to 125 MS/s on all channels and a more potent power supply (up to 800 mA). The larger buffers allow you to capture longer records at high resolution and enable more complex AWG signals. Modulated AWG signals also take advantage of larger buffers, and more complex modulated signals have been added including phase modulation and summation.

This iteration of our most popular Analog Discovery digital oscilloscope also allows engineers access to new powerful features in WaveForms like the FIR (finite impulse response) Filter. Through the use of optional FIR filters on Oscilloscope input channels, users can reduce the amount of high frequency noise that could affect the quality of their measurements. Digital loopback of captured signals to the AWG, both filtered and unfiltered, is now supported. AWG output signals can now also be recaptured through digital loopback and displayed alongside signals returned from a circuit under test.

The AD3 is built on the next generation Xilinx FPGA, opening up even more features and future enhancements over time with software updates.


The Analog Discovery 3 has access to all of the adapters and accessories from its previous version, as well as the new Audio Adapter+. These accessories, like the Transistor Tester, Impedance Analyzer, and Breadboard Adapter, are available to buy from our online store.

If you’re looking to buy an oscilloscope, the AD3 is a digital oscilloscope option that is a complete solution, meaning that you won’t have to shop for more benchtop equipment.

The Analog Discovery 3 is proudly manufactured using Texas Instruments components.

What is WaveForms?

WaveForms is the free software application for the Analog Discovery 3 and enables use of the available analog and digital instruments. The software has been refined by customer feedback for over 10 years and features a computer and laptop friendly user interface that has the feel of traditional benchtop software. The Analog Discovery 3 communicates with WaveForms via a USB connection to your computer, allowing users to capture, record, analyze, and generate mixed signal and mixed domain waveforms. WaveForms can be tested without hardware using its demo mode feature. In addition to the use of instruments in the application, the WaveForms application has a script editor tool, which allows custom scripting of the instrument in JavaScript. WaveForms is designed to be run on a laptop or desktop computer and is Mac, Windows, and Linux compatible.

The following instruments are available in the WaveForms application for the Analog Discovery 3:

  • Oscilloscope
  • Waveform Generator
  • Power Supplies
  • Voltmeter
  • Data Logger
  • Logic Analyzer
  • Pattern Generator
  • Static I/O
  • Spectrum Analyzer
  • Network Analyzer
  • Impedance Analyzer
  • Curve Tracer
  • Protocol Analyzer
  • Script Editor

For even more customization potential, the WaveForms Software Development Kit (SDK) can be used to create custom applications and scripts in Python, C, and additional languages. The Analog Discovery 3 is also compatible with LabVIEW and the Mathworks MATLAB Data Acquisition Toolbox.

    I would like it packaged similar to a Pico 2205A PicoScope 2 Channel BNC input. Great little 14-bit device. Thank you.

    Very good device for fast and highly modular testing

    Posted by Guillaume Martin on 10th Mar 2024

    I tested a few functionalities of this device and wrote a blog about it on Element14 Community ( Have a look if you consider buying this product!

    I cannot register the product. Registration page never proceeds despite I type in the registration # correctly and bought it directly from Digilent. Multisim webpage requires serial number which I never received from Digilent. So I cannot download Multisim as promised. When trying to login to Forum, "reCAPTCHA" pages were very confusing and could not pass its verification (due to unclear images). So I could not sign in to ask questions. Now I am stuck with wonderful AD3 but could not use it.

    Excellent tool

    Posted by John C. on 1st Dec 2023

    I have an AD2, and I bought this for the deeper sample buffers and other improved features. It has been invaluable for the project I'm working on right now. I missed the recent deal on the AD3, but the next time the price drops, I plan to buy a 2nd one to double the number of scope channels with "dual" mode.
