Two new methods using the concepts of cross correlation and cross variance are proposed for comparing three oscillators. They allow one to characterize individually each oscillator and they reduce the influence of the measurement system noise if the noise sources on each channel are independent. Therefore, better resolution can be obtained in the spectral purity and frequency stability measurements.
