Stores the external attenuation table in the calibration plane specified by the selectorString parameter. On a MIMO session, the external attenuation table is stored for each MIMO port in the specified calibration plane.
If there is only one table configured in any calibration plane, it is automatically selected as the active table.supporteddevices: PXIe-5663/5663E, PXIe-5665, PXIe-5668, PXIe-5644/5645/5646, PXIe-5830/5831/5832/5840/5841/5842/5860

Parameters
| Name | Type | Description |
|---|---|---|
| selectorString | string | 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. On a MIMO session if you do not specify the port name, this configuration is applied to all MIMO ports in the session for the default calibration plane instance. To configure external attenuation table for a specific MIMO port, use the port specifier with or without the calplane name. Example: "calplane::plane1/port::myrfsa1/0". Note Example:"""calplane::plane0""calplane::plane0/port::if0""port::if0""calplane::plane0/port::all"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. For a MIMO port, the valid selector string is "calplane::<calplanename>/port::<devicename>/<channelnumber>/<portname>". If you specify "port::all", all MIMO ports are considered configured. Use RFmxInstrMX.GetAvailablePorts method to get the valid port names. </portname></channelnumber></devicename></calplanename></portname></calplanename> |
| tableName | string | Specifies the name to be associated with external attenuation table within a calibration plane. Provide a unique name, such as "table1" to configure the table. |
| frequency | double[] | Specifies an array of frequencies in the external attenuation table. This value is expressed in Hz. |
| externalAttenuation | double[] | Specifies an array of attenuations corresponding to the frequency specified by the frequency parameter. This value is expressed in dB. |
Returns
Returns the status code of this method. The status code either indicates success or describes a warning condition.
