GCUFL? I have been blamed for "muddying up the waters" so to speak. So I guess I won't write a book until I know exactly what you know.
First of all do you understand QAM at all?
EXAMPLE: QAM Frequency Service Ch. PID
1 711 Mhz Starz 361 96
The list goes on and is very large.
Or are you just looking to learn QAM testing features on the SDA5000?
