Configures the center frequency of the carrier, relative to the RF center frequency.
Use "carrier<       <i>         n       </i>        >" as the selector string to configure this function.

Syntax

int32 __stdcall RFmxSpecAn_ACPCfgCarrierFrequency(niRFmxInstrHandle instrumentHandle, char selectorString[], float64 carrierFrequency)

Parameters

NameDirectionTypeDescription
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 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. The default value is "carrier0".
Example:
"carrier0"
"signal::sig1/carrier0"
You can use the RFmxSpecAn_BuildCarrierString2 function to build the selector string.

carrierFrequency[in]float64

This parameter specifies the center frequency, in Hz, of the carrier, relative to the RF RFMXSPECAN_ATTR_CENTER_FREQUENCY. The default value is 0.

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 RFmxSpecAn_GetError function.

The general meaning of the status code is as follows:
