Parameters
| Name | Direction | Type | Description |
|---|---|---|---|
| instrumentHandle | [in] | niRFmxInstrHandle | This parameter specifies the RFmx session refnum. Instrument Handle In is obtained from the RFmxInstr_Initialize function. |
| selectorString | [in] | char[] | This parameter comprises of the signal name. If you do not specify the signal name, the default signal instance is used. The default value is "" (empty string). Example: "" "signal::sig1" You can use the RFmxDemod_BuildSignalString function to build the Selector String. |
| referenceLevel | [in] | float64 | This parameter specifies the reference level which represents the maximum expected power of an RF input signal. This value is expressed in dBm for RF devices and Vpk-pk for baseband devices. The default of this parameter is hardware dependent. |
Returns
Returns the status code of this operation. The status code either indicates success or describes an error or warning condition. Examine the status code from each call to an RFmx function to determine if an error has occurred.
To obtain a text description of the status code and additional information about the error condition, call the RFmxDemod_GetError function.
The general meaning of the status code is as follows:
Value | Meaning |
