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.

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.

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.

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 Unknown 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.

Great for a home setup.
Posted by Mark Bauer on 23rd Apr 2017
I teach electrical engineering. We are looking at using the Analog Discovery 2 for student use in several of the classes. I have been playing with this thing for several weeks and am very impressed with all it can do.

Really Cool
Posted by Unknown on 29th Jan 2017
It's all the things stated above. In my lab courses I'm so used to everything being much bigger. Although these don't have the same capabilities as the bigger, clunkier, more expensive machines, these are really cool especially for a learner like me.

Decent scope, waveform generator and logic analyzer in one.
Posted by M on 29th Dec 2016
This is a decent scope and logic analyzer, and the price is right.
What is good:
* You get a scope, logic analyzer, signal generator, low amp variable power supply. That is a lot, and the price is good.
* The software is pretty good, but takes a little clicking around to learn.
Some minor gripes:
* On the MAC, the FTDI driver from diligent is a "blocker", that sometimes interferes with the OSX one, so you have to reboot before you can use your other FTDI items. This cost me a day to try to get the Analog Discovery 2 to work.
* The scope or logic analyzer are not quite fast enough for 20 MHz signals, which is what my AVR chips run at. Frequencies of 5 MHz (may be 10 MHz) are OK.
* If you are not careful, there is cross talk on the inputs, so your scope signal is not so clean. With a bit of attention it gets better.

Best USB oscilloscope I've seen
Posted by Kevin Karplus on 14th Dec 2016
I've played with the Analog Discovery 2 for a couple of days now, and it seems to be an excellent combination of a good-quality oscilloscope, dual function generator, and programmable dual power supply. The hardware is the best I've seen in a USB oscilloscope, with very clean signals and low-jitter triggering. The 14-bit 100Msample/sec resolution makes a huge difference.
The Waveforms 2015 software seems good, but I wish it had a written user's manual, as some of the functionality is a bit mysterious, and the API reference manual is no help in figuring out the GUI.

Don't search anymore
Posted by Marc Tison on 16th Nov 2016
I am a second year electrical engineering student and got this item recommended by a friend while I was looking for an oscilloscope.
If you are reading this review and you too are looking for a oscilloscope, don't search anymore. This is the EE swiss knife you need.

Absolutely incredible product
Posted by Chris on 8th Nov 2016
So I am a junior year electrical engineering student, so I'm not an industry veteran or anything like that. But I do enjoy building all kinds of projects and am passionate about circuits and design.
One of my instructors recommended the Analog Discovery for our lab assignments, and I opted not to buy one (trying to save money.) My lab partner had one, so we used his. On the first lab assignment, after seeing all the things it could do I decided to buy one.
When it arrived, in true nerd fashion I ripped into the packaging and hooked it up to some test circuits. Within an hour I was able to analyze MIDI logic data which I had never been able to do before, and I just cannot overstate how useful this thing is.
It has a great oscilloscope, a versatile function generator, DC supplies, logic analyzer and more. The only complaint I have about it is that the DC supplies and wave generator only go up to +5v/-5v, but since this thing is USB powered that is actually quite incredible in itseld because USB is 5v dc, and this thing can output double that in peak to peak voltage.
I would HIGHLY recommend this thing if you are a student or even a hobbyist. A good oscilloscope will run you about $400 or more, and this thing has a great oscilloscope plus so much more.

Best update to my tech bench yet.
Posted by Andrew B. on 29th Oct 2016
"I wish it could ..." is not a thought that has occurred to me
while using the Discovery 2. It is producing answers for development work, as well as real measurements for real problems. I might need another one.

A Well Kept Secret...
Posted by Steve Coppens on 21st Aug 2016
I would have bought the AD2 a long time ago if I had known about it!
An excellent box of tricks that works very well, but it is the software that really shines (and on Mac too...). Faultless attention to detail - much appreciated tool!

Hard to believe that you can get a whole test lab in such a small box
Posted by Robert at USC on 20th Jun 2016
This is an amazing value, and an essential tool for every electronics hobbyist and student. Even for seasoned electronics engineers, this would be a great addition to their toolbox. At low frequency (up to about 30 MHz), it basically gives you an entire suite of test equipment that fits in your backpack. It's hard to believe that this is being offered for at such low cost. My wishlist for Discovery 3 is being able to use multiple units at once to increase the number of channels, as well as current monitoring capability on the supply voltages. Other than that however, it's grand! Please check this product out. DISCLAIMER: I am in no way connected to Digilent, but I love this product!
