Parameters
| Name | Type | Description |
|---|---|---|
| selectorString | string | Pass an empty string. The signal name passed when creating the signal configuration is used. |
| centerFrequency | double | Specifies the carrier frequency, in hertz (Hz), of the RF signal that needs to be acquired. The signal analyzer tunes to this frequency. |
| referenceLevel | double | Specifies the reference level which represents the maximum expected power of the RF input signal. This value is expressed in dBm for RF devices and Vpk-pk for baseband devices. |
| externalAttenuation | double | Specifies the attenuation, in dB, of a switch (or cable) connected to the RF IN connector of the signal analyzer. For more information about attenuation, refer to the Attenuation and Signal Levels topic for your device in the NI RF Vector Signal Analyzers Help. |
Returns
Returns the status code of this method. The status code either indicates success or describes a warning condition.
