So what do you guys think about purchasing the Siglent LA probe set vs buying a decent USB- based LA? I like having HW based decoding. Im mostly doing SPI, I2S, I2C. Trying to decide whats the best way forward. Any thoughts?
I have MSO, and being able to correlate analog/digital is very useful. Also DSOs usually have great serial triggers. USB LA have very basic triggering.
SDS2000X+ has a lot of memory so it should be able to capture lots of packets, especially using segments and intelligent triggering.
My experience is that if you need to correlate analog/digital and if you are looking at decoding at "hardware" level MSO is best. Like checking if things are flowing right between components of the system.
If you need to develop/debug "software" side of protocols (data centric, developing and debugging messages itself) than USB based LA is very useful.
But with long mem scope like SDS200X+ (or Picoscope as I have) you probably can do most of what is needed. You can always buy one of those cheapo LA clones and use with Pulseview, for ultra long sequences and decode on PC. I think that would be most powerful combination.
That's my opinion based on my experience.
