Click the [A.A.F.] box, and then choose a anti-aliasing filter setting from a list.
The anti-aliasing filter can prevent aliasing distortion that may be produced during FFT calculation. The cutoff
frequency automatically changes according to the sampling rates or frequency range (for the FFT function)
settings.
Off  Disables the anti-aliasing filter.
On
Enables the anti-aliasing filter.
(Disabled when the external sampling is used, or the sampling rate is set at 100 kS/s
or faster)

Click [Sensitivity] box, and then enter sensor sensitivity.
You can enter sensor sensitivity to two decimal places. For a charge-output acceleration sensor or non-TEDS-
compliant sensor, enter its sensitivity marked on the sensor, which represents sensitivity per meter per second
squared.

Click [Close] .
The setting dialog box closes.

Example 2
For a sensor with its sensor sensitivity per gravity (G) marked.
For a sensor with its sensitivity per gravity (G) marked, enter a quotient of the marked sensitivity
divided by 9.8 m/s

To convert a unit from meter per second squared into gravity (G)
The instrument measures charge quantities per meter per second squared. You can convert such
charge quantities into those per gravity (G) using the scaling function.
Refer to “3.2 Converting Input Values (Scaling Function)” (p. 38).
Configure the scaling setting as follows;
Example 1
Specifying a conversion ratio
Ratio 0.1020E+00 (= 1/9.8)
Offset
0.0000E+00
Units G
Example 2
Specifying two points
Input1
9.8000E+00
