RFmxTDSCDMA_CfgFrequency
int32 __stdcall RFmxTDSCDMA_CfgFrequency (niRFmxInstrHandle instrumentHandle, char selectorString[], float64 centerFrequency);
Purpose
Configures the expected carrier frequency of the RF signal to acquire. The signal analyzer tunes to this frequency.
Parameters
| Input | ||
| Name | Type | Description |
| instrumentHandle | niRFmxInstrHandle | Specifies the instrument session. The RFmx driver obtains this parameter from the RFmxTDSCDMA_Initialize function. |
| selectorString | char[] | Specifies a selector string comprising of the signal name and 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. examples: "" "signal::sig1" "result::r1" "signal::sig1/result::r1" You can use the RFmxTDSCDMA_BuildSignalString function to build the selector string. |
| centerFrequency | float64 | Specifies the carrier frequency of the RF signal to acquire. The signal analyzer tunes to this frequency. This value is expressed in Hz. |
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 RFmxTDSCDMA_GetError function. The general meaning of the status code is as follows:
