Hi,

Similar to the VCTCXO measurements, we also need to do
RF-PA output
power measurements. The Racal 6103 can measure the power level of
bursts we transmit.
Attached to this mail you'll find my measurements in GSM900, ARFCN 33.
I've done some short tests for DCS1800 and higher ARFCNs in GSM900 as
well, so far the offsets to my measurements seem to be linear, so we can
most likely use a correction value and don't need to store everything twice.
I'll investigate in this later...
