The specifications page is irritating.
It has a USB "C" connector. That's Great. They don't actually say if it is USB 2 hi-speed or  USB 3 , 3.1 or whatever.

Ouch, that pricing. The AD2 was creeping up in pricing over time too.

I think they are cool devices, even if the WaveForms software has some rough spots. I have been having students use the AD2 in some feedback and controls labs I designed and it works pretty well. Due to the differential input channels its actually a very good impedance analyzer, you can measure mOhm range impedance up to the MHz range.

I wonder what the edu discount will be, education is their biggest market. They sold a whole lot of AD2s during covid when all the students had to be remote.

At a $400+ price point the AD3 (or the AD2) does not seem like a very good value for the money. Once you throw in the added cost of the BNC adapter board and oscilloscope probes the AD3 costs more than entry level DSO from Rigol/Siglent with a built in waveform generator and is not too much cheaper than a entry/edu level scope from Tek/Agilent.

i asked them for more information, and they replied, with regards to USB speed, it will still be USB 2.0

sadly, the AD3 seems like a mere incremental improvement over the AD2. They could have gone USB3 and leveraged USB C's power management thing and made the aux power connector unnecessary, but they didn't do either of those things. Another thing they mentioned was that it would still have the same 2 voltage ranges as the AD2, so the only improvements seem to be a faster sample rate, double the sample memory (and single channel can use 64k of memory), slightly higher waveforms per second, and a new case, which i'm not to fond of as i rather enjoy the AD2's translucent case since i like seeing the insides of it.

link to their post partially answering my questions: https://forum.digilent.com/topic/25916-analog-discovery-3-information/

i just noticed a curious thing, unlike the AD2, the AD3 doesn't have XILINX's logo at the bottom, nor does it have the ADI logo nor the TI logo as recent AD2s do. how curious! does that mean the end of their partnership? at least as far as providing ICs for the AD devices, hmmm!

I'd imagine it'll be 480bps hi speed based on what's not said.

Interesting they didn't go with Power Delivery, but chose an DC power jack instead, presumably based on the additional BOM cost. 

I'm sure I'll pick one up in time (I already have 2 x AD2, 1 x AD1 and 1 x DD) as the form factor & software are excellent for both field work and on-the-go hardware development, but the improvements over the AD2 are so marginal I have little incentive to dive in right away.

The potential game changers for me would have been: substantially deeper memory, increased sampling rate to 250 if not 500MSa/s, and power supplies to +/-15V.
artag:
Power Delivery is fairly widely available on chargers but is it well supported on PCs ? It certainly won't be supported from a USB 3 or 3.1 port which is often the source of a USB C cable.
