Parameters
| Name | Type | Description |
|---|---|---|
| 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. |
| iqOriginOffset | out double | Upon return, contains the I/Q origin offset of the composite signal. This value is expressed in dB. |
| iqGainImbalance | out double | Upon return, contains the I/Q gain imbalance of the composite signal. This value is expressed in dB. |
| iqQuadratureError | out double | Upon return, contains the I/Q quadrature error of the composite signal. 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.
