I will hand out all Graphs to Staszek for distribution.
Please refer to him for your documented noise head
A good noise source has an ENR with little ripple and
a flat pattern. Please consider the blue curve as a reference
for the ENR calculation
How to calculate your ENR?
Add to the value of your Noise-Source shown e.g. @1296 MHz
(1.110) to the ENR of my SNS Noise-Head @1296 MHz
(interpolation!) 5.451 + 1.110 = 6.561
The result is the calibrated ENR of your Noise-Head
