RFmxLTE_CfgNBIoTComponentCarrier
int32 __stdcall RFmxLTE_CfgNBIoTComponentCarrier (niRFmxInstrHandle instrumentHandle, char selectorString[], int32 NCellID, int32 uplinkSubcarrierSpacing);
Purpose
Configures the Ncell ID and Uplink Subcarrier Spacing parameters for the NB-IoT signal.
Use "carrier<k>" or "subblock<n>/carrier<k>" as the selector string to configure this function.
Parameters
| Input | ||
| 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, subblock number and carrier number. If you do not specify the signal name, the default signal instance is used. Example: "subblock0/carrier0" "signal::sig1/subblock0/carrier0" You can use the RFmxLTE_BuildCarrierString function to build the selector string. |
| NCellID | int32 | Specifies the narrowband physical layer cell identity. |
| uplinkSubcarrierSpacing | int32 | Specifies the subcarrier bandwidth of an NB-IoT signal. This parameter specifies the spacing between adjacent subcarriers. |
Return Value
| Name | Type | Description | ||||||||
| status | int32 | 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 RFmxLTE_GetError function. The general meaning of the status code is as follows:
