Configuring Module-Specific Settings
3
Tap the area that includes [A.A.F] .
The setting dialog box appears.
4
Tap 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)
5
Tap [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.
6
Tap [Close] .
The setting dialog box closes.
Setting example for sensor sensitivity
Example 1
For a sensor with its sensor sensitivity per meter per second squared marked
Sensor sensitivity (setting value)
1.08 pC/(m/s

) 1.08
Example 2
For a sensor with its sensor sensitivity per gee (G) marked.
For a sensor with its sensitivity marked, enter a quotient of the marked sensitivity divided by
9.8 m/s

Sensor sensitivity (setting value)
For sensor sensitivity of 64 pC/G
64.0 / 9.8 = 6.53061 ... pC/(m/s

To convert a unit from meter per second squared into gee (G)
The instrument measure charge quantities per meter per second squared. You can convert such
charge quantities into those per gee (G) using the scaling function.
See “3.2 Converting Input Values (Scaling Function)” (p. 54).
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
Scale1
1.0000E+00
Input2 0.0000E+00 Scale2 0.0000E+00
