Auto
This selection is automatically chosen when Auto Couple is pressed. When in Auto, the Sweep
Type Rules are set to Best Dynamic Range. It seems like a very simple Auto function but the use
of this construct allows a consistent statement about what the Auto Couple key does.

Best Dynamic Range
This selection tells the analyzer to choose between swept and FFT analysis with the primary goal
of optimizing dynamic range. If the dynamic range is very close between swept and FFT, then it
chooses the faster one. This auto selection also depends on RBW Type.
In determining the Swept or FFT setting, the auto rules use the following approach:
•
If the RBW Filter Type is Gaussian use the RBW for the Normal Filter BW and if that RBW >
210 Hz, use swept; for RBW <= 210 Hz, use FFT
•
If the RBW Filter Type is Flat Top, use the same algorithm but use 420 Hz instead of 210 Hz for
the transition point between Swept and FFT
•
If any of the CISPR detectors is chosen for any active trace, always use Swept.
