One presumes those that want an analyzer might know how to drive one however I didn't when I got my first one and being a dealer I couldn't not have some idea so was to some extent forced into the RF world.
Now on my third one, a SVA1032X that is also a single port VNA, it's been a fun ride but I've also ticked off some nice personal projects not possible without instruments of this type.
Are you aware the SA manual has been updated ?
Drill down here to find the User manual for your model:

I am not sure how we got from mixed signal probe to spectrum analyzer. (maybe because I loosely referred, only in my second post, to [logic] analyzer?)

Anyway, sometime I will buy an SA, I don't have room for it now. I am changing that soon, if things go well.

Sorry, yes just analyzer sent me off in another direction.

 

I don't have your scope but the color indicator is on the side of the digital probe trace usually.

Oops.
I do have the scope in a rebrand version. So I got the digital probe box for it.



Serial protocol converter PIC18F14Q41 with SPI debug display and lots of debug pins to reverse engineer data protocols.

Decoding async AND spi signals.




Maybe a 6 out of 10 for usability and signal inspection. You can't zoom inspect on when in digital mode like you can with the TEK scopes.
