IF Flatness

[Alsanie]

What does IF Flatness of the Vector Signal Analyzer mean? Is it the frequency response of the IF frequency over IF Filters?

Usually the flatness of a filter response refers to the amount of ripple in the passband.

So yes, it is the frequency response of the filter, in the passband.

Welcome, Alsanie!

Not so much "over" the filters, but the condition of the signal once "through" the filters.

This is a decent definition of Vector Signal Analysis: https://en.wikipedia.org/wiki/Vector_signal_analyzer

I would then suggest you peruse this definition of "spectral flatness": https://en.wikipedia.org/wiki/Spectral_flatness
