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 method performs a spline interpolation based on the entries above and below the row in the table.
Currently interpolation is supported only for S-parameter tables. supporteddevices: PXIe-5663/5663E, PXIe-5665, PXIe-5668, PXIe-5644/5645/5646, PXIe-5830/5831/5832/5840/5841/5842/5860

Syntax

Namespace: NationalInstruments.RFmx.InstrMX

public int ConfigureExternalAttenuationInterpolationSpline(string selectorString, string tableName)

Parameters

NameTypeDescription
selectorStringstring

Specifies the calibration plane name in which the external attenuation table is stored. This input accepts the calibration plane name with the "calplane::" prefix. If you do not specify the calibration plane name, the default calibration plane instance is used. The default value is "" (empty string).
Note

For PXIe-5830/5831/5832 devices, port names should also be specified along with Calplane names. Hence, the valid selector is "calplane::<calplanename>/port::<portname>". If you specify "port::all", all ports are considered configured. Use RFmxInstrMX.GetAvailablePorts method to get the valid port names.</portname></calplanename>

Example:"""calplane::plane0""calplane::plane0/port::if0""port::if0""calplane::plane0/port::all"

tableNamestring

Specifies the name to be associated with either the S-parameter table or the external attenuation table within a calibration plane. Provide a unique name, such as "table1" to configure the table.

Returns

Returns the status code of this method. The status code either indicates success or describes a warning condition.
