Plug and play
Posted by Jack on 29th Apr 2020
Very nice 2-channel scope and waveform generator. Very nice software and fast data transfer compared to any of my Rigols. No messy difficulties setting it up, even on Linux!
Two features I miss:
1. Real-time lock-in amplifier, i.e., the ability to stream continuous demodulated data. This requires the demodulation and filtering to happen on the FPGA, though, so perhaps it's difficult to implement with this hardware.
2. Clock ins and outs. If we could sync multiple AD2's, it would be SUPER powerful.
Still, can't go wrong for a few hundred bucks!!

Seems good so far
Posted by Unknown on 28th Jan 2020
I used this last year as a rental for school and it was always pretty straight forward and simple to use. Great for doing stuff at home. I bought one this year for myself and it works great so far. I haven’t tried to do anything to fancy yet and I know it has limitations, but it works for what I need it to do.

Great Instrument
Posted by J. Kretzschmar on 18th Dec 2019
Our university recently designed home-based labs for two online electrical engineering courses incorporating the Analog Discovery 2 in the lab kits to be provided to the students. Experience with the AD2 throughout the development of the labs has been great. We did not use all of the features, however, what we did use worked out perfectly for the purposes of the courses (+/- 5 volt power supply, oscilloscope, waveform generator, and logic analyzer). Because of the availability of the AD2 we are now able to offer a select number of courses with labs online at our university. This is a wonderful instrument for a student, or hobbyist.

Two thumbs up!
Posted by Unknown on 15th Nov 2019
I recently purchased an Analog Discovery2, as well as the Analog Parts Kit, and have been blazing my way through the Real Analog lessons found on this site (https://learn.digilentinc.com/classroom/realanalog/). Fun! The course is really outstanding, especially the included video lectures. Thank you Digilent!
The Analog Discovery2 seems well made, and so far, works as intended, but admittedly, I have not yet tried all the features. Installing the Waveform software on my mac was simple.

Excellent hardware, software takes some getting used to
Posted by Seth on 13th Aug 2019
The hardware is ideal, good number of channels and configuration options. The software is so/so, it's not very intuitive and navigation around the wave forms is very tricky. Trying to isolate specific parts of the wave form can be a trying experience. Albeit, I run on a mac and I think the software is mainly focused towards Windows users, so the navigation might be smoother on that platform.

Great piece of Hardware with a steep learning curve for customization
Posted by Unknown on 5th Aug 2019
This system works great with the out-of-the-box Waveforms software and offers a powerful SDK for customization. However, the learning curve on the development environment is very steep and the documentation at times does not include all the necessary details. I have had to ask a substantial number of 'dumb' questions on the forum to get started, and continued to do so throughout the process of developing my custom applications -- and responses to those questions are not always timely or particularly helpful. I am ultimately able to get the system to do exactly what I need it to every time, but it can be a h*** of an uphill battle.

"the Analog Discovery 2, a unit that has a long history of development, it really shows
what a mature product can do. I found little that couldn't be done with this device that any technician would need in a very portable device.
The Waveforms software is fully utilized to it's extent and I could find very little to improve on."

Great Hardware, Software, and Support
Posted by michael noel on 18th Jun 2019
The hardware and software are both great, and if there is a corner case feature that is needed they are often able to update the software to support it in a few months. Great product and great company!

Very nice product for people working in embedded systems area
Posted by Mukul Singh on 19th May 2019
I think this product should be mandatory in engineering courses owing to its all in one design. No need to switch between instruments. It helped me a lot in my research work. Even I worked it from home without going to the lab.

Died after less then one hour of work
Posted by Nikolai Starinski on 28th Apr 2019
In my opinion, there is something really wrong with the device when it stops working after only one hour of total time. As it appeared from the forum, it is not a single case.

Tons of Value for the Electronics Hobbyist
Posted by Peter Hanson on 30th Dec 2018
I deliberated long and hard before deciding to purchase this pricey product given the availability of some attractive budget digital oscilloscopes for only a hundred dollars or so more. However, in the end I went with the AD2 for the following reasons:
• Electronics is and will remain just a hobby for me. It is, however, a vast domain. Given that the AD2 is more than just a USB oscilloscope, as a mixed signal multi-function test and measurement instrument it will allow me to explore and dip my toes into many different aspects of this domain. Granted, should I decide to specialize and drill down more deeply into any given area may require additional investment in equipment in the future.
• The internal FPGA architecture of the AD2 allows for the simultaneous use of its various test-bench features in real time with minimal impact on performance.
• The general specs are amazingly good for its entry level price point to the world of digital oscilloscopes and other test equipment.
• Most of the analog and digital circuits I will likely be building in the foreseeable future fall within the ±25V, 700mA/500mW (channel/total) input and output ranges of the AD2.
• The free Waveforms software user interface looked phenomenal as it should be with such a USB-based product.
• There are a wide variety of online resources and user community forums available for the AD2.
• Very positive independent online test-bench reviews of the performance of the oscilloscope and wave generator functions.
• The compact design, quality and solid build.
• A 30% Cyber Monday discount sealed the deal.
If you find yourself seriously considering the AD2 for any of the above reasons I highly recommend you also consider the BNC Adapter Board and oscilloscope probes (Digilent SKU: 410-361, 460-004) which significantly expand the analog bandwidth of the oscilloscope function from 9MHz to 30MHz and the bandwidth of the waveform generator from 9MHz to 12MHz. According to Digilent, this is the optimal setup that allows maximal AD2 spectral performance. The flywire kit included with the AD2 is a cheap, easy-to-use probing solution. However, the kit reduces the bandwidth of the scope and is susceptible to inducing noise and crosstalk from adjacent circuits.
I also recommend adding an external 5V, 2.5A switching power supply (Digilent SKU: 300-031) and breadboard adapter (Digilent SKU: 410-361). Adding the external power supply increases the maximum output to 700mA/2.1W (per channel). The breadboard adapter comes with a half-sized solderless breadboard which when attached provides a prototyping surface directly secured and connected to the AD2.
After using the AD2 for slightly over a month, I can report the following.
Learning curve: never having had the opportunity to work with real oscilloscopes and other test equipment (apart from a DMM), I found the online tutorials and QuickStart videos on the Digilent website very helpful in getting up and running with the AD2. The ability to download and run the Waveforms software and its associated Help file on a demo basis prior to purchase also gives you a real opportunity to explore and experience the features, functions and operational capabilities of the AD2. The reference manual only provides limited technical information, so learning how to use the AD2 is mostly a DIY exploration project and falling back on the online tutorials, videos and forums when stuck. These resources provide a readily accessible on-line electronics learning “university” including formalized lectures, lab exercises and project-based learning modules.
Utility & User-friendliness:
- The free Waveforms software is easy to download and is available directly from Digilent.
- After a few initial frustrating failed attempts, setting up and calibrating the AD2 was relatively straightforward with online tutorials and videos available for assistance. But you must pay very careful attention during the measurement input process not to accidentally miss any polarity signs, decimal points or voltage measurement units that will lead to input error warning messages forcing a restart of the process.
- The layout of the Waveforms software user interface really highlights and facilitates the fully integrated operation of the 13 different functions of the AD2.
- The software works with the FPGA to control all the functional blocks of the AD2, including setting parameters, acquiring data, and transferring and storing data. It greatly facilitates the acquisition and transfer of data in a variety of formats including text, CSV, audio and images between all AD2 functions and external sources.
- Navigating the drop-down menus requires a little patience at first but with practice becomes routine.
- The waveform generator function is easy to use and can be used to drive the other functions of the AD2 as well as provide a variety of pre-set and customizable signals for external circuit and component testing.
- The built-in math functions for measurement and data crunching plus the ability to write scripts to customize the operation of various measurement functions makes the AD2 an extremely powerful analysis tool.
Impact on my ability to understand the functioning of electronic circuits and components: the AD2 provides a window to see “inside” what’s going on with electronic components and circuits in real time. As such it helps electronic theory to come “alive” in front of your eyes. It has and is continuing to take my understanding of electronics to new levels.
Bottom Line: best suited for those looking for a versatile diagnostic tool that will help them to improve their understanding of and quantitatively explore the world of electronics at an undergraduate college or university level. It isn’t cheap, but the AD2 delivers a lot of value for the money in a small package. However, for those who are already fairly knowledgeable and technically inclined (and prepared to invest a little more), some budget oscilloscopes and other test equipment may be a better option, especially if working with more complex or powerful circuits. As for me, the AD2 will be helping me to unravel electronic “mysteries” for many years to come.

Easy to the point
Posted by Bob on 16th Oct 2018
Delivery (from Taiwan to the Netherlands) was no problem (although I was really scared for Fedex :P). Im a total newb on electronics, but I got it working in no time and solved the problem where I needed it for. The tool WaveForms looks and feels awesome and is intuitive. Thank you sooo much for this product! I will also recommend it to my collegues, so be prepared for orders :).

WaveForms v3.7.12 adds data compression which lets you capture low and high speed signals together.

Logic Analyzer part is pretty much unusable
Posted by Chetan on 16th Feb 2018
The reason i bought AD2 was to have a high speed analyzer capable of capturing both Analog and Digital signals.
I have not completely tested the Analog part but the Digital signal Logic analyzer for sure is unusable.
It cannot capture low speed and high speed signals together.
Refer to this link in the discussion forum for more details.

Do not buy this product if you are looking for a good logic analyzer. May be its good on the analog side!!

Outstanding Hardware and Software
Posted by Unknown on 5th Feb 2018
I have had my Analog Discovery 2 for about a week and am very pleased. I usually struggle to find products that have Linux support!. Being able to use different functions (e.g. siggen and scope) simultaneously is quite convenient.

Great device, needs arm64 software package
Posted by Sean O'Byrne on 3rd Feb 2018
Really capable device, for the money. Add a little linux computer and a touchscreen, put them all in a box and you have a decent oscilloscope. I recommend it to students in my instrumentation course as it has everything you need when learning. The one thing I'd really like to see is an arm64 package, or better still open-sourcing the linux code. The Odroid C2 would run this device really well if I could compile the waveforms software on it.

Versatile Bench Instrument
Posted by Raymond H Colton on 19th Jan 2018
I just purchased the AD Ver 2 after having Ver 1 for several years. The performance has been very good except maybe when you are trying to generate and/or view very low voltages. But what you get for the price is truly remarkable. I also have the BDC breakout board that proves very helpful when trying to connect to more standard connectors (e.g., BNC). Wish they made a wire cable that only connected to the scope, wavegen and power pins. All those extra wires just get in the way.

Where have you been all my carrer
Posted by Unknown on 15th Dec 2017
When I read the description I thought it sounded good but then I started using it and realized it's awesome. Besides teh Scope, pattern generator and logic analyzer, I really love the protocols. Sometimes I need to interface with a chip on my board and I would normally have to program an Arduino to allow me to talk to a SPI or I2C device. Now I just plug in this thing and I can quickly try out a few commands or write a small script to do it.
I must say the scripting environment can be improved. I would also like to see the Python API with official I2C support. You could argue that I might dock a star for these gripes but they are so small compared to what I can do with the tool.
I've bought my dad one of these and I might buy myself a second just so that I don't have to keep taking it home.
This is really worth the money.
