Abstract

A combined signal level meter and leakage detector having a built-in antenna for the leakage detector, and dual clock frequency control of the microcontroller along with bandwidth switching for greater sensitivity in leakage detection mode. A data logging function is also provided. Control circuitry is also provided for avoiding receiver spurs by combined switching of multiple local oscillator frequencies, including combinations of high-side and low-side injection and IF shifting.
