Hi,
I wonder could we use a channel simulator to test a BTS instead of the handset? Then it will be very valuable.

Hello,
I've picked up what appears to be most of a Rohde & Schwarz TS8916B GSM Type Approval system (CRTC02 equipment, a Sofimation SOFI05 radio channel/fading simulator and various RF switching) and wondered if it may be of use in testing the baseband. Or can everything we would want to test be done using simple MS test equipment and/or a BTS with OpenBSC?
I did also wonder whether it would be possible to use this to try and achieve type approval, but realise that even if the rest of the hardware could be gathered together it would be a huge learning curve and even then maybe you have to be accredited/authorised for TA (or other challenges would prevent this). In any case, I thought it worth asking the question before it is split up.
Regards,
Andrew

The digital units are PCs running DOS and tests are written in C and compiled to run on DSP boards (2x TX + 2x RX per CRTC02 digital unit) which drive the attached analogue units. GPIB is used for control between these and to also control the SOFI, RF switches and other equipment that is missing (a signal generator and a second SOFI at least).
