The present invention is directed towards a channel power monitor for monitoring channel power levels for each of N signal channels. The value of each channel power level is designated as p(&lgr; ), where &lgr; is a channel parameter that characterizes each channel. An embodiment of the invention includes a variable channel attenuator having M attenuation profiles where M&gE;N, and where a k-th attenuation profile is characterized as a function of the channel parameter &lgr; by A (&lgr; ). This embodiment also includes a detector for measuring a k-th integrated attenuated power level, the value of which is represented by P . An analysis unit receives all of the values P of the integrated attenuated power levels and thereupon derives the values p(&lgr; ) of the channel power levels by solving a set of linear equations.
