Buying advice DSLogic U3Pro16 vs Analog Discovery 3 vs ADALM2000
mindentropy:
I have decided on buying a decent logic analyzer after working with Saleae LA and previously with oscilloscope protocol decoding. I am confused with what whether to go with DSLogic U3Pro16, Analog Discovery 3 or the ADALM2000. The latter 2 have decent pattern generator which I feel might be very useful if I am designing something. U3Pro16 looks very good. I would like to hear opinions on my shortlist.
RAPo:
I have the DSLogic U3Pro16, works as advertised.
Before we can give sensible advice, what are your requirements?
What is the intended use, how many channels, max speed, do you need buffer and streaming mode?
If you want a CCC (cheap Chinese clone) of theAD3/AD2k take a look at the vimu mso21.
mindentropy:
Channels: I am looking at 16 channels. I thought of the 8 channel models but looking back I have used that many channels mainly for marking something using GPIOs.
Buffer or Streaming: I am looking at streaming mode with option of buffer mode to perform maybe operations before sending out.
Interface: Looking at USB3 for better bandwidth and reduce problems of streaming.
Speed: As high sampling rate as possible. DSLogic provides very good sampling rate of 1GHz. This might future proof my investment.
My main use case would be learning, debugging, reverse engineering of unknown protocols, finding exploits etc. I am looking at decent protection for I/Os and support for a good range of IO voltages. I am also stuck with whether I would need a pattern generator as it looks so useful for testing my design and drivers and it is found in ADI3 and ADALM2000. Unfortunately ADI3 and ADALM2000 have only USB2 and sampling is much lesser but I am not so sure whether it is good enough for my present and future use cases.
RAPo:
Channels requirement --> Both AD3 and DSLogic have 16 channels
Streaming: both will do, DSlogic gives you a streaming speed of 16G/number of channels in use, I would choose the DSLogic
Interface requirement: both have USB-C.
Speed requirement: AD3 atmost 125MS/s, DSLogic 12:channels 250MHz, 16 Channels 125MHz per channel. I would choose the DSLogic.
Intended use: just tinkering, learning: go with the AD3, in production use I would choose the DSLogic.
Pattern generator: only AD3.
Overall choice: DSlogic.

TomKatt:
I have the DSlogic Plus and it has worked quite well. Though the newer Pro models may technically sample up to 1GHz, even the 400GHz sample rate of my Plus model is overly optimistic - it's virtually impossible to have a test lead setup capable of those speeds.
So unless you need some special feature of the Pro model, save 50% and look into the (now) base model Plus. They run the same software, which is actually fairly nice.
But the AD3 is certainly the most flexible of the bunch.
