11. A method for determining an RF frequency of a component of an RF signal, said method comprising:
mixing said RF signal with a first multi-tone LO signal comprising a plurality of tones to generate a first mixed signal;
filtering said first mixed signal to remove signals outside of a predetermined band from said first mixed signal to generate a first IF signal;
mixing said RF signal with a second multi-tone LO signal comprising a plurality of tones to generate a second mixed signal;
filtering said second mixed signal to remove signals outside of a predetermined band from said second mixed signal to generate a second IF signal; and
determining said RF frequency of a component of said RF signal utilizing said first IF signal and second IF signal, wherein said second multi-tone signal has a different plurality of tones from said first multi-tone signal.
