Tell me, please. I'm confused.

The input range from RFfreq to LO1freq + IF1freq?
But why then the intermediate frequency (IF) is defined as LO1freq - RFfreq?
LO - a constant frequency? That is, the oscillator is not rebuilt?

Usually, the intermediate frequency is defined as the difference between the central frequency and a central oscillator (carrier) frequency of the high frequency signal
