*'''Overlap''': defines the amount of overlap of blocks of signal between 2 successive Order FFT computations expressed in revolutions, from 0 to 1/Order resolution For example: if ''Order resolution'' setting is 1/8, then Overlap range is from 0 to 7. | |||

* '''Angular Overlap''': defines the overlap (in angle) corresponding to a rotation fraction. This setting is comprised between 0 and 1 rotation-SOA angular resolution with one rotation equal to 2*PI or 360° depending on the physical quantity used for the angle. The resolution (in radian) is equal to 2*PI/number of samples per rotation (=(number of lines -1)*2.56*order resolution). This setting is only available for a spectral averaging mode (in time domain it is forced to 0 and it is not modifiable). To have the maximal overlap when the resolution is <nowiki><</nowiki>1, the "Overlap" and the "Overlap in rev" must be at their maximum. | * '''Angular Overlap''': defines the overlap (in angle) corresponding to a rotation fraction.
