RF control
The purpoase is to check the receiver or transmitter without going in call. It works very much
like a call, but you have control via the PC and not via the tester. If you want to tune or calibrate
at other channels or levels than the default for that function, you can activate RF control at the
same time and change the wanted parameters.
