The attenuation of adapters and relays as determined from NF degradation. The loss of DUT9
(Jan 30 2013)

The average S/N is -0.1758 dB without the DUT9. Inserting DUT9 degrades the S/N to -0.2370 which means that the NF degradation caused by DUT9 is 0.0612 dB

The measurement is made with brand new adapters having the original contact pressure of BNC connectors.
