int32 __stdcall RFmxWCDMA_CfgNumberOfChannels (niRFmxInstrHandle instrumentHandle, char selectorString[], int32 numberOfChannels);
Purpose
Configures the number of user-defined channels for the measurement. This function is used when you set the
RFMXWCDMA_ATTR_CHANNEL_CONFIGURATION_MODE attribute to RFMXWCDMA_VAL_CHANNEL_CONFIGURATION_MODE_USER_DEFINED. Call this function before you call the
RFmxWCDMA_CfgUserDefinedChannelArray function or the
RFmxWCDMA_CfgUserDefinedChannel function.
Use "carrier<n>" as the selector string to configure this function.
Parameters
| Input | ||
| Name | Type | Description |
| instrumentHandle | niRFmxInstrHandle | Specifies the instrument session. The RFmx driver obtains this parameter from the RFmxWCDMA_Initialize function. |
| selectorString | char[] | Specifies a selector string comprising of the signal name and carrier number. If you do not specify the signal name, the default signal instance is used. Example: "carrier0" "signal::sig1/carrier0" You can use the RFmxWCDMA_BuildCarrierString function to build the selector string. |
| numberOfChannels | int32 | Specifies the number of user-defined channels. |
Return Value
