Thank you for your reply. On one level, I am relieved that this wasn't simply a case of operator error or failure to RTFM. On the other hand, though, I am faced with a bit of a quandary. It simply didn't occur to me that the serial decoding was limited to the analog channels, and there is no way in the demo software to test this, since the virtual demo scope is a four-channel analog DSO. Serial decoding of the logic analyzer data streams was on my list of essential features when I was shopping for an MSO. Therefore, if there is any chance that serial decoding of the digital channels of the 2205 MSO might not be added to Picoscope 6, then I would have to rethink whether this MSO meets my needs.
I know that any sensible developer will refuse to speculate about future software releases, but I really must ask: do you have any sense of when Picoscope might support serial decoding of the digital channels of the 2205 MSO?
Thank you once again for your prompt response to my inquiry.
