Have you tried or tested the digital discovery?

Two reasons: (1) the designers did it for the look, or (2) so they can know you opened it and deny warranty coverage (illegal to do so in some countries, but they still try). Maybe even a bit of both.

Yeah, it's dumb.

They do that to save you from yourself. Anyone who has had to do customer service/troubleshooting for either internal or external customers knows what I'm talking about.

That's exactly what I instantly thought! 😂

Helmholtz resonance frequency matches the sample rate for improved jitter reduction.

@@EEVblog Hahaha, nice!

me too, and I just find it has the ability to make a bode plot with a click, love more

Since this is from the pro line it probably isn’t designed for students. Since this just seems like a better AD 3 then that would probably be a better choice for students.

@@conorstewart2214 Thanks for fhe reply, appreciated.

I haven't used the software, but if it has a traditional "scope-like" interface, then probably ok to use in an educational setting, but if students use this are dumbfounded when they go to use a hardware scope in a job later, then it's probably not the best thing to teach them on. The scopes in my udergrad labs were all TDS-1000 series, and when I bought my own good scope (an HP 54645D), I was amazed at how much more useful it was to have more than 2 waveform updates per second! The TDS-1000 also had permanent persistence turned on - just because those LCD screens were slower than molasses in January in Canada!

I would argue that the learning curve for students shouldn't be any worse than using a normal version of whatever it is you want to use, scope, logic analyser, function generator, etc.

@@gorak9000 The bench setups have a Tektronix MSO2014 and a Tektronix 2-channel arb generator, Global Specialties breadboard, Fluke meter and sundry supplies. The textbook specified in the curriculum is Floyd’s Digital Circuits book. I get the second semester which covers mid scale functions and basic FPGAs. The FPGA work is on a DE-10 board based on the Max10. The way I’ve approached the labs is to start with electrical properties comparison of TTL and CMOS based on Floyd ch. 15. Next we go though building several projects from mid scale integration parts, translate some of those projects into FPGA using Quartus Prime schematic capture and end with a simple VHDL program compiled into a functional block and deployed as a component of a schematic capture. That may not sound like a lot but it does a pretty good job of filling 15 3-hour labs in an undergrad course. Something which surprises me is students, even if they’ve used oscilloscopes before, often don’t understand the reason to use a X10 probe for taking high frequency measurements or how to compensate said probe. I have a hand-out and worksheet on the matter which goes along with the electrical characteristics lab. We have National Insturments ELVIS breadboards which are designed to work with using Multisim for schematic capture. We switched back to using the Gloabal Specialties breadboards which much older because students constantly blew the fuse on the 5 Volt supply on the ELVIS. The Global Specialties unit has electronic protection which resets itself.

Haha, like the Young brothers of AC/DC, maybe he also is an Aussie from Scotland. 😄

​@RK-kn1ud it's really disingenuous that he doesn't label the video as a promotion/sponsor might even be illegal

LOL !

@@humble2246I think this might be count as sponsor because it’s a mail bag. But in general it’s good to disclose it.

@@humble2246 You must be new here, welcome. One of my most popular segment is literally called Mailbag, where companies just send me stuff.

You are paying for the software really.

@@EEVblog as you are for in scopes these days. Like yeah, hardware costs what it costs but majority of stuff people choose one scope over other is software. Shame there isn't any open hardware worth mentioning for scopes

I also bought an AD1 from ebay recently, thay go for the cheapest price, though there's not much difference between the models

If you use self tappers, if you pretap it should be less of an issue? You can also close the channels, but the extrusion will cost a little more.

​@@jaro6985 These were BOPLA Alubos enclosures with self tappers. We switched to the Alustyle with closed channels.

As it is just FPGA with few ADC/DACs you could technically "just" write alternative firmware for it. Or alternative client sofrware That being said SDRs got far cheaper and you'd be getting much wider frequency range out of it... and for the saved money also buy a scope. This thing is overpriced

You wouldn't get much by connecting an antenna to the input. It's missing the RF front end circuitry that an SDR has. It would only be able to receive very strong, nearby signals.

@@rocketman221projects That too. You could attach frontend and a mixer generating IQ signal then send it to ADP but at that point buying existing SDR is cheaper.

Once you get into that price range it is usually better to just buy cheap individual devices, like a cheap 2 channel scope and a cheap logic analyser. At those requirements you may even be able to get away with a decent microcontroller if you can live with the 0-whatever voltage range. I think there are some basic scope projects using microcontrollers, I think there was one for the rp2040 with not too bad inputs.

@@conorstewart2214 I know that it is, even better with 2nd hand, but it should not need to be. the needed parts are cheap, an STM32 or similar instead of a FPGA should be enough for example. Also not many students have the place for power supply, function generator and oscilloscope.

Isn’t the ADC only rated for 125 MS/s but the op amp is rated for 1 GHz.

Using the 125 MS/s ADC to meassure a 30MHz signal is already a stretch. That only gives you 4 Sample points for each period of a 30 MHz signal.

Why not? Can good stuff only be made in USA or something? Sometimes the better stuff comes from where you least expect... I've "recently" found out that Poland makes a lot of excellent stuff at great prices, honestly i would never guessed that some years ago.

@@tiagoferreira086 Never said ONLY IN THE USA. Just not a country you think of for "TECH". Like Taiwan, Japan, China, Germany, UK, South Korea, Switzerland, Sweden, to name a few. THOUGH, cute you thought I meant only USA. I mean personally, my default would be Japan first and foremost.

​​@@tdata545Production cost in eastern european countries is still a lot lower, many western companies have factories there.

IT industry in a development country always develops the best as it doesn't require massive investments like for example in semiconductors which is reserved for most advanced countries.

@@tdata545it’s funny you say about the USA. When I see made in the USA on tech products I always assume it will be fairly low quality

AvE hammer trumps screwdriver

For the buffer size, as explained in the caption.

@@jaro6985 did you read my comment before you replied? If all they wanted was a larger buffer then why upgrade to a bigger FPGA rather than adding RAM? All the extra resources in the larger FPGA other than the block ram will be wasted unless they added extra features that used them.

@@conorstewart2214 Most FPGA designs use a small fraction of their total capability.

@@jaro6985 still not the point even if true, FPGAs are expensive, you want to use the smallest one you can manage with. From what I could see they doubled the cost of the FPGA used in the board just for extra buffer size.

@@conorstewart2214 this design is not price optimized. That and the $10 difference, I think can be covered by the ~$400 increase in price over AD3.

You could just look it up. Like most of the analog discovery series it is a combination oscilloscope, function generator, logic analyser, digital signal generator, data logger and a few other things. Its main advantage is the software which can combine many of the functions together to perform things like frequency or voltage sweeps as well as having add-on boards that can be used for curve tracing or impedance measuring.

Rambo pfft.. Crocodile Dundee

Test equipment. Primarily used in a lab environment with students. You can generate, analyze, monitor and play with waveforms. There is also a multimeter and logger function. Meh, very narrow bandwidth. I don't see the point of such a thing for my own personal or professional use.

I agree, what an ugly color, almost any other color would be better...even if it was pink lol

ye.. so ugly...

It's a digital oscilloscope without a screen.

@@MrCuddlyable THANK YOU!

Several people have said this. Noted. I've done several videos on the Digilent Analog Discovery before, so it's kind a implied knowledge on this channel. But I can understand some people might just be seeing this video and have no idea.

​@@EEVblog I'm an old timer who likes a chance to ramble and I see a chance here. It's about the urge to help that exists in electronics both amateur and professional. A long time ago I was a lad who wandered into a radio/TV workshop to ask what the coloured bands on a resistor meant. The salesman took 4-5 minutes to explain it all. A week later I came back holding another resistor, expecting to be spoon-fed the ohms value. The salesman remembered me and curtly said he had customers waiting and that by now I should read resistor bands myself or buy myself a multimeter. This was also very good advice. Now to answer in the same spirit to @schitlipz: BNC is the name of the quick-on quick-off connectors on signal cables that have been popular for ages and are just what we like to find on test equipment. For advanced learners, "BNC" stands for "Bayonet Neill-Concelman" and BNC connectors are suitable for coaxial cable connections for all but very high frequency (over 1 or 2 GHz) or high power connections. I step aside now because now you've read my yadda-yada there is surely a queue waiting and eager to explain about FPGA, bandwidth, , Analog, digital,.....

Noted.

Both true. Straight up aluminium is kinda useless nasty gummy stuff, so practically all .... practical aluminium is alloyed with something to suit the processing and application. This one would be alloyed with material to improve extrusion. Then chopped off and anodized. So both "alloy" and "anodized".

It being made of an alloy and it being anodised is not mutually exclusive.

Me open mailbag. Me shoot video. Me shash open. UG.

Yep, thats the long and short of it alright and it was awesome ! if not a little out of character🤪.@@EEVblog
