Specify the cutoff frequency of the high-pass filter in this selection box for
input Force signal. Before you click on the Scan button, select a cutoff fre-
quency lower than that selected in the Start Frequency/kHz selection box.
After you have finally determined the oscillation frequency, you have to set the
cutoff frequency to the value nearest to but lower than that specified in the
Frequency/kHz selection box.
Specify the cutoff frequency of the low-pass filter in this selection box for the
input Force signal. Before you click on the Scan button, select the cutoff fre-
quency higher than that selected in the Start Frequency/kHz selection box.
After you have finally determined the oscillation frequency, you
cutoff frequency to the value nearest to but higher than that specified in the
Frequency/kHz selection box.
Specify amplifier gain for the signal that has passed through the high-pass and
low-pass filters. Usually, set it to 10.
This filter is used for the signal that has passed through the high-pass and
low-pass filters. Usually, set it t

Shifter slider enables you to control the phase, which can be set in the

If this box is checked, the phase rotates by 180° from the present angle. Since
the operation is performed by the hardware, the preset value of phase rotation
on the software does not change at all.
