Abstract
In accordance with an embodiment, an apparatus for analyzing signals comprises a spectrum analyzer and a frequency extension module. The spectrum analyzer includes an IF switch which switches between an internal IF signal and an external IF signal, and a LO coupler which is configured to output a portion of one or more LO signals. The frequency extension module is configured to receive the one or more LO signals from the spectrum analyzer and send an IF signal to the spectrum analyzer. A diplexer band switch is used to direct the low band signals to the spectrum analyzer and to direct the high band signals to the frequency extension module where they are downconverted to the external IF which is output to the IF switch.
