"Measured" loop suppression curve
a
result of the loop suppression measurement performed by the E5505A
system.
"Smoothed" measured suppression curve
b
is a curve-fit representation of the measured results, it is used to
compare with the "theoretical" loop suppression.
c
"Theoretical" suppression curve
predicted loop suppression based on the initial loop parameters
defined/selected for this particular measurement (kphi, kvco, loop
bandwidth, filters, gain, etc.).
"Adjusted" theoretical suppression curve
d
through

value of suppression for this measurement. It is based on changing loop
parameters (in the theoretical response) to match the "smoothed"
measured curve as closely as possible.
