Attributes

Specifies the expected carrier frequency of the RF signal that needs to be acquired. This value is expressed in Hz. The signal analyzer tunes to this frequency.

Specifies the attenuation of a switch (or cable) connected to the RF IN connector of the signal analyzer. This value is expressed in dB. For more information about attenuation, refer to the Attenuation and Signal Levels topic for your device in the NI RF Vector Signal Analyzers Help.

Specifies the reference level which represents the maximum expected power of the RF input signal. This value is configured in dBm for RF devices and as V_pk-pk for baseband devices.

Specifies the margin RFmx adds to the RFMXSPECAN_ATTR_REFERENCE_LEVEL attribute. The margin avoids clipping and overflow warnings if the input signal exceeds the configured reference level.

Specifies the time, in seconds, to wait before results are available in the RFmxSpecAn Attribute. Set this value to a time longer than expected for fetching the measurement. A value of -1 specifies that the RFmxSpecAn Attribute waits until the measurement is complete.

Specifies the instrument port to be configured to acquire a signal. Use RFmxInstr_GetAvailablePorts function to get the valid port names.
