3. Press .
4. Press
.
5. When the analyzer finishes the sweep, notice the mean value, which appears on the
analyzer display.
6. Use the following equation to convert the linear magnitude mean value to log
magnitude:
Power (dBm) = 20 × [log
10
(linear magnitude mean value)]
7. Write this calculated value in the performance test record in dBm.
