And now setup with a LAN connection to PC at the bench a webserver capture and remote screenshot of how the Serial Test parameter values are adjusted.

--- Quote from: Wilson__ on September 12, 2024, 08:15:30 pm ---Effective ADC bit (ENOB) is about 1.5 to 2 less than the specification?  8 bit ADC has 6 bit real accuracy and resolve 64 steps of digital SPI signal.  Would that be enough for task below?

How much sampling rate do I need to see the signal, without risk of missing some short time glitch?  SDS2104 is 1GSa/s when all 4 ch activated, right?  For 20MHz SPI clock, 50 dots per cycle. Enough?

On speed alone, Rigol MSO5074 is exceptional high 8GSa/s for 700 UK pounds.

Divided down by the # of channels in use, as is the memory depth.
I don't remember by how much but a search should reveal the facts.

OTOH SDS2000X Plus uses 2 ADC's, each 2 GSa/s and with 200 Mpts memory each, therefore 1 GSa/s and 100 Mpts memory depth with all channels active.

oh!  14 pages long.

It will be 100 dots per cycle in 2 ch mode but need alternate trigger than directly decode the 4 actual signal wires of SPI.

Many thanks for the info.  That is very nice and neat. 

World moved on.  Would take lot of human  to move cursors (since time of CRT analogue scope with digital marker/cursor) and copy the timing number. now is auto
