Stepped scans must dwell at each frequency for one second. f

is the
tuned frequency, not the starting frequency. Usually, for analog scans,
the frequency range is broken into octave or decade bands and the
scan rate is changed at each band. The following table shows
suggested bands and analog scan rates. For stepped scans, the
frequencies may be computed using equation 9.
Frequency Band Analog Scan Rate Total Scan Time
30 Hz–100 Hz 2 Hz/s 35 s
100 Hz–200 Hz 8 Hz/s 12.5 s
200 Hz–400 Hz 17 Hz/s 11.8 s
400 Hz–700 Hz 32 Hz/s 9.3 s
700 Hz–1.5 kHz 61 Hz/s 13.1 s
1.5 kHz–3 kHz 127 Hz/s 11.8 s
3 kHz–6 kHz 250 Hz/s 12 s
6 kHz–10 kHz 460 Hz/s 8.7 s
10 kHz–20 kHz 850 Hz/s 11.8 s
20 kHz–40 kHz 1.7 kHz/s 11.8 s
40 kHz–100 kHz 3.8 kHz/s 15.9 s

4. If susceptibility is noted, select three or more test frequencies per
octave at frequencies where susceptibilities are present. For example,
if five frequencies within an octave show susceptible responses, select
at least three of them for further testing. The three selected should be
those with the maximum indication of susceptibility.
