Parameters

selectorString  String

Specifies a selector string comprising of the result name. If you do not specify the result name, the default result instance is used.

timeout  Double

Specifies the timeout for fetching the specified measurement. This value is expressed in seconds. Set this value to an appropriate time, longer than expected for fetching the measurement. A value of -1 specifies that the method waits until the measurement is complete.

meanIQOriginOffset  Double

Upon return, contains the mean averaged origin offset of the received signal. This value is expressed in dB.

meanIQGainImbalance  Double

Upon return, contains the mean I/Q gain imbalance of the received signal. This value is expressed in dB.

meanIQQuadratureError  Double

Upon return, contains the mean I/Q quadrature error (phase imbalance) of the received signal. This value is expressed in degrees.

maximumIQOriginOffset  Double

Upon return, contains the maximum origin offset of the received signal. This value is expressed in dB.

maximumIQGainImbalance  Double

Upon return, contains the maximum I/Q gain imbalance of the received signal. This value is expressed in dB.

maximumIQQuadratureError  Double

Upon return, contains the maximum I/Q quadrature error (phase imbalance) of the received signal. This value is expressed in degrees.
