General DSP processing question

Thank you for your valuable responses.

To clarify : I can stop on any frequency and process the signals in as much
time as I need (ultimately I need this to be as short as possible)

Thank you

Sweeps in wobblers are rarely linear ( fixed increment )
because that would be too slow. They are usually exponential
or double-exponential, getting faster to the higher frequencies.
How fast depends on the settling time of the object one is
testing.
As far as i remember one can do up-sweep and down-sweep
and compare both results: if they do not match one should
slow down.

Thanks all for responding.

I can dwell on any frequency and sample for any length of time (but this
needs to as short and quick as possible)

Thank you.
