Setting FFT Calculation Conditions
4
(When you choose [Exponential] in the [Window] box)
Tap the [Attenuation ratio] box, and then enter an attenuation rate.
0.1%  to 99.9%
Noise superimposing on attenuating waveform is mitigated.
Attenuation rate: 10%
100%
10%
5
Tap the [Compensation] box, and then choose a compensation method for an attenuation
from the list.
The instrument compensates an attenuation of a calculation result for effect of the use of a non-rectangular
window function.
None  Does not compensate any attenuation for effect of the use of a window function.
Power Compensates an attenuation for effect to correct energy of time-domain waveform to
an equivalent level of energy generated when multiplied by a rectangular window.
Average Compensates an attenuation for effect to correct an average of a time-domain
waveform to an equivalent level of an average calculated when multiplied by a
rectangular window.
Choosing [Rectangular] in the [Window] box fixes a correction value to a factor of one (0 dB).
