The screen dump provides the following info where the NF of the LNA itself is assumed to be 0.2874 dB and the dissipative loss of all DUTs are assumed to be 0.1084 dB. The average of NONE is 0.3142 dB which means that (0.3142 - 0.2874 + 0.1084) = 0.1352 dB has to be added to levels with cable combinations to get the corresponding NF values with negative sign.
