More Information
Summary:A method for measuring a power level of a radio frequency signal in a radio frequency transmitter includes routing a portion of the radio frequency signal to a detector, detecting a signal envelope of the radio frequency signal with the detector, routing the detected signal to a digital signal processor, and talking at least one sample from the detected signal envelope using the digital signal processor and determining a detected power level of the radio frequency signal from the at least one sample, wherein the at least one sample lies in a portion of the detected signal envelope having a known non-random sequence.
