External Attenuation Interpolation

Selects the linear interpolation method when interpolating S-parameters for the specified table. If the carrier frequency does not match a row in the S-parameter table, this function performs a linear interpolation based on the entries above and below the row in the table.

Selects the nearest interpolation method when interpolating S-parameters for a specified table. The parameters of the table nearest to the carrier frequency are used.

Selects the spline interpolation method when interpolating parameters for the specified table. If the carrier frequency does not match a row in the S-parameter table, this function performs a spline interpolation based on the entries above and below the row in the table.
