Pulse Stability is a measurement to characterize the amplitude and phase variation of successive pulses over time.
A stability value for each individual pulse is the deviation of the pulse amplitude or phase from a reference value, measured at a selected point, you set in the Pulse Meas Point Reference property within the pulse.
The reference value is the mean of the amplitude/phase over a range of pulses within burst and then averaged across all bursts. It must be measured over the most stable part within the burst to remove initial settling effects. You must configure the Pulse Stability Ref Offset property to ignore the number of starting pulses for reference value calculation.
For the average stability results the deviation measured values are mean squared over a range of pulses and then converted to dB. You must configure the Pulse Stability Meas Offset property to ignore the number of initial pulses for statistical average value calculation.
With multiple burst of pulses, at first, the deviation values are position averaged for each pulse position across all bursts. Positional average increases the sensitivity of measurement by suppressing the variation that occur over the multiple bursts. The resultant positional average deviation values are mean squared to get average stability results.
Additionally, you can perform carrier frequency offset (CFO) compensation on the measured phase values before the stability calculation.
