USB logic analyzer - what's the current "favorite" for ~150$? Hantek 4032L?

The DSLogic Pro has a 400MHz sample rate, so you should be able a 50MHz SPI signal

but sample rate is sample rate and maximum input bandwitch is another case
i think this limitation 50mhz in old dslogic version causes this problems

Isn't bandwidth measured on each channel?

There are some other threads and the sigrok wiki where the differences are discussed.

Things which might matter for performance:
- Probes, do they have internal compensation circuitry
- Is probe wire coax or plain wire
- Internal components forming termination on the board, circuitry may have changed on the newer models?

If you have a decent scope it might give you some clues when probing.

The oldest model uses 0.1" headers:

thats right thanks
i have a shorts in original cable perhaps sticker makes this shorts
after removed this sticker and cleaned connector i gets correct log

btw. where i can buy good quality dslogic connector without shorts which will fit to older version which i have ?

I'm not aware of any sources. You could ask the aliexpress sellers or directly.
At some point I was thinking of making the PCB's myself and then running some 1.13mm coax for cabling (https://www.aliexpress.com/item/32973720198.html or similar).
