I am using Genesys 2012 software in order to simulate generated signal and noise of the system, simply speaking, it generates a CW signal. In order to calculate generated signal and noise I use a system simulation which gives these values. As the result the software gives a spectrum with a phase noise in dBm from the CW value. So in order to get the phase noise I calculate \$ N_{phase\_noise, dBm} = P_{peak,dBm} - P(freq)\$, the values are given for 1 Hz of a bandwidth. The Genesis software gives two different values of \$P_{peak}\$, namely "total" and a value at the node. It is not clear for me if I should take a total or a node value? Does someone knows if Genesis calculates all the reflected signals and noise power in order to get the total value?
