As a scientist experimenter, I tried the supported values and measured
sweep duration for 30*255 points between 200MHz and 300MHz For 255 pts
5 -> 3.93 s
10 -> 2.47 s
20 -> 1.25 s
30 -> 0.841 s
40 -> 0.611 s
60 -> 0.382 s
which is roughly invert-linear.
As a scientist experimenter part 2, I tried unsupported in-between
values. Every values I tried seems to fallback to a duration of 0.6s
/255pts, corresponding to 40 (6.2 kHz) (default for the 'pro'
?)...except for 50 which gave me 0.458s/255pts. The interpolation on the
previous duration measures gave me an IFBW between 8.2 kHz and 8.4 kHz.
Is 50 an undocumented supported value corresponding to IFBW = 8.2k or 8.3k ?
