ADF4350 frequency sweep

Me and my friend are using the ADF4350 synthesizer in a project of ours.

We're looking for information about how the actual frequency sweep works - and mainly, what could be the minimal approximate delay between each spacing. It is possible to jump between frequencies in less than 10ns, just when you alternate between 2 frequencies. But I suppose that when using multiple registers to perform a sweep, it takes time to shift data from one place to another.

Right now, the software won't let us perform a sweep with an approximate delay of less than 1msec. We would like to know why!
