Name | Type | Description |
instrumentHandle | niRFmxInstrHandle | Specifies the instrument session. The RFmx obtains this parameter from the RFmxLTE_Initialize) function. |
selectorString | char[] | Specifies a selector string) comprising of the signal name and the result name. If you do not specify the signal name, the default signal instance is used. If you do not specify the result name, the default result instance is used. Example: "signal::sig1" "result::r1" "signal::sig1/result::r1" You can use the RFmxLTE_BuildSignalString) function to build the selector string. |
