I love good logic analyzers. I use them for research, diagnostics and reverse engineering. They are not replacement for scopes, of course not. But scopes are not replacement for logic analyzers either. I already had two high performance ones. And I just acquired a third one:

These are sometimes mentioned as Saleae clones. They have much better specs than the Saleae and at a fraction of the price. I have a Saleae Logic Pro 8 already for quite some time, and it is fair to say that it is (or at least it was until now) my favorite logic analyzer. It is very reliable, high quality, it has awesome support and top notch software. The DSLogic doesn't feel to be quite at that level, but having better specs at a fraction of the price, it is unbeatable.

Unlike the Saleae, the DSLogic devices don't have analog measurement. This is a nice feature that it is sometimes very useful. Other than that, the DSLogic specs are awesome and it is very affordable considering the capabilities:

Does it work with the Saleae software? As you mention, that's top notch and a big reason I still use my crappy streaming 16 channel barely able to keep up LA instead of my 32 channel 150MHz Hantek one most of the time.

No. It's not really a Saleae clone, not in that sense. I suppose they sometimes called it a clone because it can do USB streaming, as the Saleae. Actually it can do both USB streaming and internal capture. That's one of the big pluses over the Saleae.

They use their own open source software, forked in turn from Sigrok Pulseview. It is not bad at all. I only performed just a couple of tests. It is very powerful. But certainly not visually as pleasant and neat as Saleae software.

Saleae used to be affordable. But their prices skyrocketed during the chip shortage and they never looked back. They don't even offer the student discount for the Pro devices anymore. Only the "Startup" discount, which is just a $100 US discount.

Even after the discount, the Saleae Pro 8 ($849) is much more expensive than the 32 channels DSLogic Pro ($399). And if you compare the Saleae Pro 16 ($1349) vs the the DsLogic Pro 16 ($299), it is almost ridiculous. Let alone, again, that the DSLogic Pro has higher specs, faster sample rates, than the Saleae Pro.

I've got the same one and I'm really quite happy with it, especially for the price.
The one negative, as already mentioned, is that it doesn't do analogue.
I find the software quite nice. Perhaps not as polished as Saleae but still good, and it supports a bunch of protocol decoders.

I have one of their DScope series as well but I haven't really used it enough to give a verdict, other than it seems fine too.

Hi. Did you have a chance to test the scope?

It hasn't seen much action in quite a while. I did use it during initial bringup of the Raven board and I can't say I had anything to complaint about.
Having these USB devices by my desktop computer is really handy since the workbench where I have the standalone scope and soldering stuff etc is in a bit of a different location.

Thanks for the comment. I'm considering purchasing their new portable low cost scope ($99 50MHZ):

Yeah, not meant for "serious" work. But for basic troubleshooting on the go it's fantastic. Sometimes all you need is to check if a clock is working, or if you have pulses in the signal and stuff like that. And as you are saying, on the go is not only for traveling. Just that it's portable enough so that you easily and quickly use it on some other table or desktop, it's fantastic.
