a 20 Hz loop bandwidth was used
with
the

A
measurements are more accurate
because the impact of the PLL is
removed. At higher offsets, the
measurements are also more
accurate because the E5052
spectrum analyzer has a much
lower noise floor than the E4445A
spectrum analyzer. Even though

feature,
it
only
cancels out the thermal noise. It
does not cancel out the phase
noise of the LO inside the
E4445A.
