The 141T is hardly a poor instrument, but a better way to put it might be
that it just doesn't have the resolution bandwidth to get as close to the
carrier as you have pointed out needs to be seen. That, and we may be
running into reciprocal mixing with the residual FM (phase noise) of the
spectrum analyzer's local oscillator. This has always been a limiting factor
for using a spectrum analyzer to look at close-in signals (to a strong
carrier). Warning: this is all conjecture, as I have not bothered to look at
8553 residual FM specs.
