The analog hardware takes a finite amount of time to switch 
frequencies.  During that time, there will inevitably be *some* type of 

A PLL synthesizer will take some amount of time to change frequency.  
Every time you change frequency, you take it out of its converged state, and
   it has to re-converge.
