Forward and Reflected Power
Average power is a measure of the equivalent “heating” power of a signal, as
measured with a calorimeter. It measures the total RF power in the system, and
does not depend on number of carriers or modulation scheme.
Average power is the most important measurement of any transmission system
since the average power is normally specified on the operating license. It is also
valuable as a maintenance tool, showing overall system health, and for calibration.
