RF POWER MARGIN

1. The amount of transmitter power above that which is computed by the link designer as the minimum required to meet specified link performance. Note: The rf power margin allows for uncertainties in (a) empirical components of the signal level prediction method, (b) terrain characteristics, (c) atmospheric conditions, and (d) equipment performance parameters. ( 188 ) 2. At any given time in an operational link, the reserve transmitter power over that which is required to maintain specified link performance.
