Abstract
A leakage detector includes a receiver front end having an input for connection with an antenna and a signal path including circuitry for passing a signal from the input without amplification; an IF stage connected with the receiver front end for producing an IF signal therefrom; a detector for producing an AM detected output signal in response to the IF signal; a leak processor for passing only a synchronizing signal of the AM detected output signal, along with harmonic frequencies of the synchronizing signal and DC signals, the synchronizing signal having a peak level, and the signal processor providing an output corresponding to the peak level of the synchronizing signal of the AM detected output signal; a display; and a processing unit connected with the leak processor and the display for displaying leakage data in response to the output signal from the leak processor.
