Hi again,
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.
The Tx power is set at "dsp_api.db_w->d_power_ctl = ABB_VAL(AUXAPC, 0xC0)" so we need to determine for which AUXAPC value we get how much power at the antenna connector.
Using the resulting table of measurement results, we can compute what AUXAPC value we should use for what intended transmit power.
I am aware that those measurements should idaelly be done on each and every phone, as they might differ. However, I'm quite confident that by using values that are correct on one phone, we shouldn't be too much off on other phones. At least not by an order of magnitude ;)
Thanks in advance, Harald
