What is the Analog Discovery 2?

If you're wondering where to buy an oscilloscope or how to buy an oscilloscope, you've come to the right place. Digilent Analog Discovery 2 is a USB oscilloscope, logic analyzer, and multi-function instrument that allows users to measure, visualize, generate, record, and control mixed-signal circuits of all kinds. Despite our competitive oscilloscope price, we never compromise on quality. Developed in conjunction with Analog Devices and supported by AMD University Program, this compact oscilloscope is small enough to be a pocket oscilloscope, but powerful enough to replace a stack of lab oscilloscopes and equipment, providing engineering professionals, students, hobbyists, and electronic 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 software (Mac, Linux, and Windows compatible), this small oscilloscope can be configured to work as any one of several traditional test and measurement instruments including an Oscilloscope, Waveform Generator, Power Supply, Voltmeter, Data Logger, Logic Analyzer, Pattern Generator, Static I/O, Spectrum Analyzer, Network Analyzer, Impedance Analyzer, Protocol Analyzer, and Curve Tracer.

USB Oscilloscope

Analog Discovery 2 among compatible add-on boardsThe Analog Discovery 2 oscilloscope is designed to be a portable alternative to a stack of benchtop equipment. It's durable enclosure measures (3.23 inch x 3.25 inch x7/8 inch) and fits in a pocket. The Digilent Discovery 2 can be connected to circuits and designs via the included female flywires, or used in conjunction with the included gender changers when a male connection is necessary.

Accessories can be purchased separately to provide additional functionality, such as the BNC Adapter for higher bandwidth and BNC connectors, or the Breadboard Adapter and Breadboard Breakout for a direct connection to the breadboard, or the Impedance Analyzer for additional Impedance measurement functionality. The Analog Discovery 2 comes packaged in a durable project box that will fit all the included accessories and some additional adapter boards. The project box measures (7" x 5.75" x 1.5") and provides even more durability when stashing your portable Oscilloscope and multi-function instrument in your backpack or briefcase.

    RE: Logic Analyzer part is pretty much unusable

    Posted by attila on 23rd Feb 2018

    WaveForms v3.7.12 adds data compression which lets you capture low and high speed signals together. https://forum.digilentinc.com/topic/9043-capturing-both-uart-and-spi-data-on-analog-discovery-2/?do=findComment&comment=27866 For deep logic analyzer buffer see the Digital Discovery.

    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. https://forum.digilentinc.com/topic/9043-capturing-both-uart-and-spi-data-on-analog-discovery-2/#comment-27505 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 Digilent Customer 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 Digilent Customer 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.

    Love it. So flexible. Would be amazing with 4 analog in and out

    Posted by Brendan Simon on 23rd Oct 2017

    This does everything you need (analog in/out and digital in/out). If this had 4 analog in and 4 analog out it would be totally amazing -- Could have a 4 channel scope and could do things like 3-phase (or 4) waveform generation (instead of having to PWM digital outputs)

    Amazing Tool

    Posted by Digilent Customer on 28th Aug 2017

    I am an Electrical Engineering student and can say hands down this is the most versatile and useful tool I own. If the Analog Discovery II had just the network analyzer it would still be worth the money. I am one of few students at my school that can test the frequency response of the circuits I create from home. The network analyzer is very useful when creating filter circuits, especially when the filters are tunable and I need to dial them in. Additionally, every time I implement circuits that communicate via SPI, I2C, or UART I have a known good tool to interface with the suspect circuits allowing me to more easily identify where errors may be occurring. Furthermore, because you can send and receive with common hardware protocols it is easy to quickly spin up a debug interface via UART. Additionally, the logic analyzer is great and has a programming interface so you can write a custom protocol analyzer when reverse engineering communications or decoding more obscure protocols. Lastly, it is small and USB powered so I just have it in my electronics tool bag and can analyses and inspect most things I run into without having to take a circuit to a well-equipped workbench. If you get the Analog Discovery II I would recommend also getting the expansion circuit that has the four BNC connectors so you can use probes with the oscope and function generator. Thank you so much for creating this tool and having a software interface that is so easy to work with.
