), Low Level Points
Note
Low level measurements are made with a measuring receiver, relative to
levels previously measured with the power sensor. Two levels (-43 dBm and
-53dBm) are used as reference points to provide the required UUT
hardware configurations for the subsequent tests. It is important that the
correct sequence is followed as described.
