For example, if:
RF power measured at −11 dBm in step 3b or 5b = −10.2 dBm
RF level measured at −83 dBm in step 7i = −70.1 dB
RF level measured at −83 dBm in step 7j = −52.6 dB
RF level measured at −101 dBm in step 7k = −73.2 dB
the corrected level at −101 dBm is −10.2 + (−70.1) − (−52.6) + (−73.2) =
100.9 dBm. Compare the corrected values with the limits in the PTR.
