So do I understand that by itself, the unit handles 900 and 850, and the add-on gives it 1800 and 1900 ?
The HP8922M can't simulate a GSM-850 network, only GSM-900 (E-GSM is also possible). The optional extension unit adds GSM-1800 and GSM-1900. However it is possible to generate various GSM test signals on the whole frequency range the HP8922M supports (10 MHz to 1000 MHz for the HP8922M alone) which includes GSM-850. This is uselful for Layer-1 development like it was done for OsmocomBB. And as hint: look for a HP8922M which has the optional spectrum analyzer built in, it can be very usefull sometimes.
