[Premium-Rx] R&S PR100 IQ demodulation mode?

[Marco IK1ODO -2]

If I understand your message, the "I-Q demodulation mode" sends I and 
Q baseband analogic signals to an output. If this is correct, you may 
use one of several programs available on the web to process and 
demodulate - like Winrad by I2PHD or one of it's derivatives. Take 
the baseband signals and feed a sound card input; or take the data 
files and send them to the program. Winrad accepts Microtelecom's 
Perseus wave format, so possibly some tweaking of formats may be 
necessary. I may help if this is the case.
Then you may parse the spectrum chunk and listen/see the signals.
A BFO could simply be a downconversion (numeric) oscillator used to 
bring that chunk of band around zero Hz. Not necessarily for SSB or 
CW demodulation - it may be a different parlance.
