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.
