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.

You do not need to use a selector string to configure or read this property for the default signal instance. On a MIMO session, use port::<deviceName>/<channelNumber> as a selector string to configure or read this property per port. If you do not specify port string, this property is configured for all ports. Refer to the Selector Strings topic for information about the string syntax for named signals.

The default value is 0.
