RFmxInstr Get S-parameter External Attenuation Type (VI)

Instrument Handle In identifies the instrument session. Instrument Handle In is obtained from the RFmxInstr Initialize NIRFSA VI or the RFmxInstr Initialize NIRFSA (Array) VI.

Selector String specifies the calibration plane name in which either S-parameter or 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).

On a MIMO session if you do not specify the port name, this VI will return an error. To get S-parameter external attenuation type from a specific MIMO port, use the port specifier with or without the calplane name. Example: "calplane::plane1/port::myrfsa1/0".

Note   For PXIe-5830/5831/5832 devices, port names should also be specified along with Calplane names. Hence, the valid selector string is "calplane::<calplaneName>/port::<portName>". For a MIMO port, the valid selector string is "calplane::<calplaneName>/port::<deviceName>/<channelNumber>/<portName>". Use RFmxInstr Get Available Ports VI to get the valid port names.

Example:

""

"calplane::plane0"

"calplane::plane0/port::if0"

"port::if0"

"calplane::plane0/port::myrfsa1/0"

"calplane::plane0/port::myrfsa1/0/if0"

error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

Instrument Handle Out passes a reference of the instrument session to the next VI.

S-parameter Type returns the type of S-parameter which is applied to measurements on the specified port of a Calplane.

error out contains error information. This output provides standard error out functionality.
