Please suggest a good cheap USB 16CH logic analyser

My interest was peaked but after reading through this thread on the ADALM2000 it sounds like a product that is not ready for release (understatement). Someone waited a year for a delivery from Mouser.

Not saying you should buy it, but availability is not an issue. Mouser has 248 in stock. AD themselves have ~1,800 in stock, according to Digikey.

Their wiki is down, which is not too encouraging.
But scopy program seems to be under some development: https://github.com/analogdevicesinc/scopy

I own both ADALM2000 and DSLogic Plus.
IMHO, DSLogic Plus is better if what you want is logic analyzer only. It has better sampling rate, trigger features, and less bugs (Scopy crashed more often).
Being said that, Scopy (of ADALM2000) is also quite usable.

The best part of ADALM2000 is that it comes with everything - oscilloscope, signal generator, logic analyzer, programmable power supply, digital I/O, etc.
And most of them can be used in parallel, as long as pin doesn't conflict. Scopy can create separate window for each function, so you get to use all features concurrently.
ADALM2000 is capable of setting up a simple end-to-end complete lab test configuration.

So if you just want a logic analyzer, then just go with DSLogic Plus.
But if you do not have other equipments and do not need advanced features of DSLogic Plus (advanced trigger, 400MHz sampling), then go with ADALM2000.

had Saleale clone 16ch is that on ali for $40,  its OK, but wasn't deep enough on 4+ channel usage due to short buffer , after that the speed drops dramatically,   12Mhz, If i remember correctly ... usb 2.0 speed ... , buffer for 8ch ,maybe fraction of seconds....

so i purchase DSLogic, it has 2 versions , basic and pro,
price:  https://www.aliexpress.com/item/32905798335.html
conversion:  https://time4ee.com/news.php?readmore=453

there are 2GB buffer: but it significantly beyond my budget

you may consider usb scope + 16ch :

I've recently had my interest peaked on logic analysers.  First I bought a 24Mhz Cypress 8 channel Sale clone for £8.95 in the UK.  It's cheap and cheerful and works with PulseView and there's a short video on how to set it up here:



The issue I had with this setup, is sometimes the unit seems to go dead and unplugging/replugging the device didn't help, only a reboot seemed to fix it.  It does work with the latest Salea software, but if you've used it with PulseView, you need to go into device manager/update driver/let me choose/Salea driver.

Unsurprisingly, the next issue was speed.  At 4 samples minimum, you're looking at 24/4 = 6Mhz max speed.  I'm playing with an ILI9341 display and understand the SPI can work up to 30Mhz which I'd like to do.

after some poking around, I came up with the LA5016 from Kingst here:

It's a shame that it's not supported by PulseView atm although the LA2016 is planned.  The things I liked about it were:

1) At 500Mhz, that's around 125MHz signals max @16CH
2) It has 1Gbit on board memory
3) It has compression (run length encoding)
4) The manufacturer's software looks good http://www.qdkingst.com/en/download
5) I emailed them some questions and they answered same day.

It should be delivered either Saturday or Monday so I'll report back with any comments.

Although I'm still new and playing, I've found logic analysers with a PC to be *much* easier that my "improved" DS4014 with serial decode.  27 button presses later.... :scared:
