I agree. A modern machine adjusts the raw data or
elegant mathematical description of
this effect.

I am just now gotten very interest on this subject. I think you mention a key
factor: antenna factor. The SA noise floor unit is dBm. After you have added
the antenna factor the unit is dBuV/m. Everything else being perfect, zero
loss, 0 dBi antenna gain across frequency, etc., the antanna

I would like to explain to a colleague why the noise floor on a SA does
not look flat as it sweeps across a given frequency range after antenna
factors, cable factors, external gain and external attenuation are
programmed into its display function.
I think it breaks down to these fundamental
