FesZ -- this was a very timely review. I was looking at getting one of these for the very reason you mentioned -- measuring and documenting the feedback loop of some switch mode PSUs.

Addicted to your channel

Many thanks for the review. A curve tracer is especially nice to have!

Awesome review !....cheers RIP Calculon

Really really great devices by analog device. I am using those for last 3 years. It’s too good for that price and has a lot of features

Thanks for the great review! I hope in the next videos you can show us how to make Phase Shift PWM signals to control a single-phase inverter-based only on duty cycle.

Thank you very much!

I wanted to buy one when they came out many years ago. At the end, I decided to buy a 100MHz dual channel scope that has a sig gen and spectrum analyzer built it, for less money! AD2 is a great tool when you're a student and have to bring your own lab equipment. After that, not much space saving with having to use a laptop to operate these headless units.

These aren't just for hobby or education, they're invaluable on the professional bench too: I have two of the AD 2s, an original Analog Discovery 1 and a Digital Discovery. The second AD 2 I bought in a bricks and mortar store in Tokyo when I'd forgotten to pack it into my baggage. For the logic analyser, there are more decoders than most scopes, for example 1wire. The biggest drawback of the LA is the limited memory depth. I use the power supply quite extensively, especially for unit testing, but most of my work is in the low power mixed signal world, and as such the current limitation isn't a problem for me, and I don't even use the external barrel connector supply input. Note that they are limited to +/-5v. It would be more useful if they went up to, say, +/- 15v for some analogue applications. The default scope inputs are differential which might confuse newcomers: the impact of this is that most of the time, when used in unipolar mode, the -ve input is simply tied to the DUT's ground. I rarely use the BNC adapter in the use cases I have. The software is about as good as it gets for a USB instrument. There are occasions when it's a little frustrating to find out how to do things, generally leading to a minor fit of random button pushing. The best feature for me is its form factor: I can take it anywhere, and pre covid I used it frequently on long journeys, and when on the bench, it takes up little space. Unfortunately the price has been creeping up over the years. At one time the original AD 1 was $99 to students and $199 to others: it was an absolute steal at those prices. It's now $279 academic pricing and £399 list. There were shortages at the beginning of Covid, presumably when students weren't able to get into the labs. IMHO, even at $399, this is a worthy addition to any EE bench.

I've had one of these for a while, its a lab in a box.

Nice having a sort of Bode 100 and Saleae 8 under the same roof, but you just can’t expect the same performance with Analog Discovery 2 (on certain characteristics). I find very unique the digital pattern generator, which is very useful for FPGA debugging. The bundle has some meh small test hook clip grabbers. The support from the forum is pretty good and prompt. My 2 cents.

apply dry putty, then cover in foil. if needed 4 shielding:)

Often you can pick these up second hand from EE graduates who just needed it for school. I paid about 160 USD for mine, and at that price it's certainly well worth it.

That scripting capability and impedance measuring, is what makes this unit a must have for some. If you need these functions, $400 it's very cheap.

Great intro. Would you make a video on how to design a DIY 2GHz spectrum analyzer using modern ICs?

Si eres estudiante, investigador u otros relacionado con la educación puede solicitar el precio de estudiante que es un 30% más barato ,actualmente con ese descuento es 279dolares y no 399 dólares que es su precio de lista.

$466 ! build my own! DIY

Interesting ! 👍🏻🤝🏻🇳🇱 Is there a reason for the black tape on the powersupply you have on the bench in many videos?

I’m glad I found mine on FB. And the kicker. The seller looked at my profile. Discovered I was Christian and sold me the discovery 2 and the BNC board for 100.

It's a nice gadget. Sadly, one needs a laptop or a desktop to use it and that cancels out the small size.

One thing that bugs me about these Discovery products (I have a Digital Discovery) is the *&^%$# I/O wires, and not even the electrical properties. Why oh why couldn't they use rainbow ribbon cable that uses wire colors that we are either already familiar with, or which it's useful for the youngsters to learn anyway. As it stands the wires are in completely useless nondescript pastel lavenderish (?), burgundy (?), green and beige (?). I mean, as engineers, we don't even have words for three of these "colors"! And that list of four repeats every four wires, so it's incredibly easy to get them mixed up -- as I have even seen on a product demo video. I do see in your video that AD2 has some other colors thrown in at one end.
