A low-cost comb generator based on a PLL scheme is presented in the paper. It can be used for investigating the characteristics of test sites, where a wide band analysis in the range 600MHz -12GHz with a compact and portable device may quickly provide the required results. The good spectral purity, tunable generated frequencies and long-term stability characteristics of the generator make it useful also for other interesting pre-compliance tests. Detailed description of critical design issues may be useful to an EMC designer for a better comprehension of low-noise PLL circuits

Abstract
A low-cost comb generator based on a PLL scheme is presented in the paper. It can be used for investigating the characteristics of test sites, where a wide band analysis in the range 600MHz -12GHz with a compact and portable device may quickly provide the required results. The good spectral purity, tunable generated frequencies and long-term stability characteristics of the generator make it useful also for other interesting pre-compliance tests. Detailed description of critical design issues may be useful to an EMC designer for a better comprehension of low-noise PLL circuitsFile in questo prodotto:
