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

The S/N is -0.1757 dB without the DUT9. Inserting DUT9 degrades the S/N to -0.2350 (average) which means that the NF degradation caused by DUT9 is 0.0593 dB

The measurement is made with all the contact fingers of the BNC male ground connection bent outwards to increase the contact pressure.
