The Power Meter autorange boundary may coincide with a
measurement point. To avoid unwanted Power Meter autoranging
during the adjustment process, manually lock the Power Meter range
when the UUT indicates the current adjustment point is a Transfer
Point and maintain the Power Meter range lock for all frequencies at
that amplitude. When the sequence reaches the next Transfer Point
allow the Power Meter to autorange and then manually lock the
Power Meter range again, continuing in this fashion for all points
requiring use of the Power Meter.

Depending on the actual configuration of the Spectrum
Analyzer/Measuring Receiver used, the settings required to make
the highest accuracy level measurements may vary. Consult the
Spectrum Analyzer manufacturer's manual for further information.
For each frequency it is important to maintain consistent
analyzer/receiver settings as the target amplitude changes. For any
given frequency the Analyzer setting can be to suit, but that setting
must be maintained for all amplitudes at that frequency after the
transfer point. In particular, analyzer attenuator, reference level and
resolution bandwidth settings must not change. Typically, there are 3
or 4 amplitudes per frequency point during which the Analyzer
settings must be static.
