RFmxWCDMA_CfgRF

This parameter specifies the RFmx session refnum. Instrument Handle In is obtained from the RFmxInstr_Initialize function.

This parameter specifies a Selector String comprising of the signal name. If you do not specify the signal name, the default signal instance is used. The default value is "" (empty string).

Example:

"signal::sig1"

You can use the RFmxWCDMA_BuildSignalString function to build the selector string.

This parameter specifies the center frequency of the acquired RF signal for a single carrier. For multicarrier measurements, the This parameter parameter specifies the reference frequency for the values in the RFMXWCDMA_ATTR_CARRIER_FREQUENCY attribute. This value is expressed in Hz. The default value of this parameter is hardware dependent.

This parameter specifies the reference level that represents the maximum expected power of an RF input signal. This value is expressed in dBm for RF devices and V_pk-pk for baseband devices. The default value of this parameter is hardware dependent.

This parameter specifies the attenuation of a switch or cable connected to the RF IN connector of the signal analyzer.

For more information about attenuation, refer to the RF Attenuation and Signal Levels topic for your device in the NI RF Vector Signal Analyzers Help. This value is expressed in dB. The default value is 0.
