	You COULD look at these signals  with either a logic analyzer or
a DSO with relatively deep storage.... or both.  Likely they  consists
of 8 or 16 or 24 bit word containing one I or Q sample sent bit
serially - or perhaps two words (I and Q) after each frame sync pulse.

	Using this for anything would require some hardware to take
the serial bits and clock them into some kind of register for access
by software on a processor (presumably a PC)...
