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.

Best regards,
  Dieter
