Abstract:
1. A system for detecting the ON/OFF ratio of radio frequency signals, comprising: means for receiving low band and high band signals from a signal source; a first set of components including a linear detector and a logarithmic detector, said detectors being independently connected to an output of the means for receiving; a second set of components including a mixing stage, wherein inputs of said first and second sets of components are coupled to the output of the means for receiving; a first routing relay in communication with outputs of the linear detectors and the logarithmic detector to output one of the outputs of the linear detectors and the logarithmic detector; a second routing relay in communication with an output of the first routing relay and an output of the second set of components, the second routing relay being in communication with at least one digitizer, wherein the at least one digitizer receives signals processed by at least one of the first set of components and the second set of components; and means for constructing a composite waveform from output signals received independently and at different times from the linear detector and the logarithmic detector.
