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

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