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