There are a lot of HP/Agilent 8922M units for sale very cheap (less than
US $500).
I know that these devices can simulate a GSM base station, but does that
simulation occur over the air, or do I need to connect my handset I am
testing to the 8922M with a cable ?
I know I need to get a 8322A expansion for the unit - any other details I
should look out for ?
Also, what is an equivalent test unit for WCDMA (3g) base station
simulation (I know these will be more expensive).
Thanks.

It has an N connector for RF output. If you connect an antenna you
can test over the air. It can output a fair bit of power, don't have
to use that if sitting in front of it.
We did some successful initial tests with one of these at one of the
Osmocom User Group meetings maybe a month ago. We briefly discussed
that it would be interesting to extract test results from it
programmatically, and perhaps also to control it. I don't know if
any effort has started in that direction however.

That's the 1800 MHz option, yes? Maybe you want 1900 instead. There
are also goodies like the improved performance 10 MHz reference.

So do I understand that by itself, the unit handles 900 and 850, and the
add-on gives it 1800 and 1900 ?

Sounds like it - good!
What kind of tests would you like to do? Depending on what you want
to do, a different tester may be even better.
