Specifies whether to enable interpolation of error terms for corrected VNA measurement. This property is used only when you set the Correction Enabled property to True.

Specifies whether to enable interpolation of error terms for corrected VNA measurement. If set to True, the interpolated error terms are used for each measurement frequency point, for which error terms do not exist in the calset, provided that minimum calset frequency <= measurement frequency and <= maximum calset frequency.

The impact of interpolation on the accuracy of the VNA measurements strongly depends on the measurement conditions and can range from severe degradation to no degradation at all. In case the phase difference between two consecutive error terms e[n-1], e[n] exceeds 180deg, the interpolation will lead to large measurement errors.

You do not need to use a selector string to configure or read this property for the default signal instance. Refer to the Selector Strings topic for information about the string syntax for named signals.

The default value is True.
