The recommended Power Meter has Power Sensor calibration
factors stored internally in the sensor. Setting the input frequency in
the Power Meter automatically selects the appropriate cal factor for
the measurement. However, the Power Sensor may also be
accompanied by a table of calibration factors which must be applied
externally.
11. Allow the Power Meter reading to settle. Record the measured level in dBm
The Power Meter autorange boundary may coincide with a
measurement point. To avoid unwanted Power Meter autoranging,
manually lock the Power Meter range once the 100 kHz reading is
obtained and maintain the Power Meter range lock for all
subsequent frequencies at this amplitude.
12. Set the UUT frequency to the first test frequency listed in Table 3-25.

If a Power Sensor with other than the recommended 2.92 mm RF
input connector is used, the insertion loss of any connector adapter
must be taken into account at each measurement frequency.
15. Set the UUT to the next frequency point at this amplitude listed in Table 3-25,
The highest frequency tested is 26.4 GHz. This frequency helps
prevent attempted measurements at the 26.5 GHz maximum
frequency limit of the Spectrum Analyzer/Measuring Receiver used
in subsequent parts of this procedure. This small frequency margin
allows for any residual frequency difference errors that may
otherwise take the Spectrum Analyzer/Measuring Receiver beyond
its operating frequency range.
