Abstract:
1. A method, comprising: tuning a selected frequency sub-band having a center frequency and a bandwidth from an input signal received from a transmitter, in which tuning the selected frequency sub-band comprises: selecting a first frequency sub-band for a first filter by selecting a first frequency for a first radio frequency (RF) synthesizer to be mixed, with a first mixer, with a signal at the input of the first filter and to be mixed, with a third mixer, with the output of the first filter; and selecting a second frequency sub-band for a second filter by selecting a second frequency, different from the first frequency, for a second RF synthesizer to be mixed, with a second mixer, with a signal at the input of the second filter, such that the second frequency sub-band at least partially overlaps the first frequency sub-band; generating a detector output corresponding to RF power in the selected frequency sub-band of the received input signal; and recording the detector output for the selected frequency sub-band.
