5. When the analyzer finishes the sweep, notice the mean value (which appears on the
analyzer display).
6. Convert the measured linear magnitude mean value to log magnitude, using this
equation.
Power (dBm) = 20 × [log
10
(linear magnitude mean value)]
NOTE Notice that the mean value that is displayed on the analyzer is in µU units.
So, for example, if the displayed value is 62 µU, the value that you would put
in the equation is (62 × 10
−
6
).
7. Write this calculated value on the performance test record.
