[Ground-station] DVB Monitoring, was: Need advice on DVB-S2 modem

[Art Towslee]

Stan,
I can't accurately answer because Charles Brain G4GUO did all software. 
I don't know what the Wireshark dissectors are. I DO know that it is 
easy to record a snapshot of the received transport stream and view the 
computer data with standard analyzers. We provide a "record" feature 
where pressing the button will store the continuous transport stream 
until the button is again pressed. The receiver does have an internal 8 
bit parallel transport stream but it is not wired out. It goes directly 
to the USB controller chip.

The associated free MiniTioune software we provide with the 
MiniTioune-Express receiver has a lot of diagnostic features including a 
constellation display. *Charles, can you elaborate on this?*
Art.
