Abstract
In a channelized system having a plurality of channels, an input spectrum having a plurality of signals is received by a receiver ( ). A first attenuation value (V ) is applied to a first variable gain device ( ) and a second attenuation value (V ) is applied to a second variable gain device ( ), wherein the first variable gain device ( ) and the second variable gain device ( ) are within a common signal path. The receiver ( ) is tuned to a desired channel and a first power level is measured within the desired channel. The receiver ( ) is selectively tuned to at least one additional channel and a second power level within the at least one additional channel is measured, independent of the first power level. Based on measuring the power levels, a first modified attenuation value is applied to the first variable gain device ( ) and a second modified attenuation value is applied to the second variable gain device ( ).
