Video demonstrates a 8-channel 1st gen Saleae Logic clone and claims that it's a modern equivalent...not quite. The Saleae clone--just as the original--is a sampling logic analyzer, whereas a true logic analyzer is driven by state transition.

To be sure, the Saleae clone depicted is reasonably useful to just under 12 MHz (at 24 MHz sampling rate), although forcing it to alias is easy and it's pretty useless for troubleshooting glitches.

You’re absolutely right of course. But I think the comparison was just a bit of fun. The Saleae is aimed at hobbiests. If they’d wanted to do a fair comparison they could have used a modern keysight logic analyzer or MSO...

The Saleae logic analyzers are really terrific value and utility and I really encourage everyone not to buy clones but instead support the team by buying the real deal. Through the last years I've bought >5 units (at various places) and can't really see myself working without one.

I'm glad seeing them hiking the prices, since the previous one was really a steal, too good to be true really.

I personally own a orignal 1st gen 8-channel unit, and despite newer gens being hardware-wise more capable, I still find this legacy device useful, in particular, for deep probing JTAG TAPs.

The price hike was painful though, and definitely not justifiable by hardware despite being well manufactured. They also make some fairly bold claims by stating that it directly "Works with RS-232, 422/3, 485", although I'd be willing to bet none of their units would survive anything close to full admissible voltage range per respective TIA spec let alone properly handle termination, which is a real trap for the occasional hobbyist. Hardware aside, I think the real value is in software UX, which they've executed quite well.
