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.
Claims14
A combined signal level meter and leakage detector, comprising:
- a first RF input;
- a second RF input;
- a wideband dual-conversion receiver front end connected to said first RF input;
- a single-conversion receiver front end connected to said second RF input;
- an IF stage having an input connected to said dual-conversion receiver front end and an input connected to said single-conversion receiver front end;
- a detector having an input connected to said IF stage;
- a processing and control circuit having an input connected to said detector;
- display means for selectively displaying signal level data and leakage data provided by said dual-conversion receiver front end and said single-conversion receiver front end, respectively.
