Specifies the test receiver attenuation for the selected segment. This property is used only when you set the Sweep Type property to Segment and Segment Test Receiver Attenuation Enabled property to True. This value is expressed in dB.

The receiver that measures the scattered waves traveling away from the DUT port and towards the VNA port is referred to as the Test Receiver. VNA uses Test Receiver Attenuation to attenuate the RF signal before it reaches the downconverting mixer on the path towards the Test Receiver.

Use "port::<portname>" as the selector string to configure or read this property for a specific VNA port for segment0. Use "port::all" to configure this property for all VNA ports for segment0.

Use "segment::<segmentnumber>/port::<portname>" as the selector string to configure or read this property for a specific segment and for a specific VNA port. Use "segment::all/port::all" as the selector string to configure this property for all segment and for all VNA ports.

The default value is 0 dB.
