Phase of phase calibration signal at the individual video-converter with ambiguities fixed minus phase of phase calibration signal averaged over the band. Contribution of cable calibration and averaged phase of phase cal to the differential phases is estimated and subtracted. Argument of the plot is time in hours elapsed from the first observation of the session. Values are in radians. Argument of the plot is time in hours elapsed from the first observation of the session.
Values are in radians.
A normalized amplitude of a phase calibration signal should be stable. However in the presence of spurious signals , the amplitude of phase cal signal is changed. In the case when spurious signals have constant amplitude, harmonic variations can be detected in the plots of dependence of the normalized amplitude of phase cal to its phase. Argument of the plot is a phase of the phase calibration signal with fixed ambiguities. Values are a fraction of a voltage of the normalized amplitude of phase calibration to the total power.
