Parameters

NameTypeDescription
selectorStringstring

Pass an empty string. The signal name that is passed when creating the signal configuration is used.

timeoutdouble

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.

iqOriginOffsetout double

Upon return, contains the I/Q origin offset. This value is expressed in dB.

iqGainImbalanceout double

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

iqQuadratureErrorout double

Upon return, contains the I/Q quadrature error. This value is expressed in degrees.

Returns

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