GetExternalAttenuationTableActualValue(string, out double)

Specifies a Selector String comprising of the signal name and calibration plane name. 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, you must use "port::<devicename>/<channelnumber>" as part of the selector string to read the external attenuation table actual value for the specified port. If you do not specify the signal name, the value is returned for the last committed signal instance.
example: "" "signal::sig1" "calplane::plane0" "signal::sig1/calplane::plane0" "port::rfsa1/0" "signal::sig1/port::rfsa1/0" "calplane::plane0/port::rfsa1/0" "signal::sig1/calplane::plane0/port::rfsa1/0"</channelnumber></devicename>

Upon return, contains the external attenuation table actual value applied to the measurements for a specified signal and calibration plane. This further includes interpolation of the external attenuation table based on the specified signal. On a MIMO session, this value corresponds to a specified port. This value is expressed in dB.
