10. Scale Setting Button
Clicking this button while the filter control field
is in graph display mode displays the dialog for
setting the graph’s scale.
A. Minimum frequency settings
B. Maximum frequency settings
C. Maximum amplitude settings
E. Step settings
D. Minimum amplitude
settings
a. Minimum frequency Settings
Sets the minimum frequency for graph display
(i.e. sets the left edge of the graph).
The downward pointing triangle button
decreases the frequency and the upward
pointing triangle button increases the
frequency.
Clicking the frequency indication in the center
opens the dialog for frequency entry.
B. Maximum frequency Settings
Sets the maximum frequency for the graph
display (i.e. sets the right edge of the graph).
The downward pointing triangle button
decreases the frequency and the upward
pointing triangle button increases the
frequency.
Clicking the frequency indication in the center
opens the dialog for frequency entry.
C. Maximum amplitude Settings
Sets the maximum amplitude for the graph
display (i.e. sets the upper limit of the graph).
The downward pointing triangle button
decreases the amplitude and the upward
pointing triangle button increases the
amplitude. The amplitude varies by values set
in the Step settings each time the button is
clicked.
Clicking the amplitude indication in the center
opens the dialog for amplitude entry.
D. Minimum amplitude Settings
Sets the minimum amplitude for the graph
display (i.e. sets the lower limit of the graph).
The downward pointing triangle button
decreases the amplitude and the upward
pointing triangle button increases the
amplitude. The amplitude varies by values set
in the Step settings each time the button is
clicked.
Clicking the amplitude indication in the center
opens the dialog for amplitude entry.
e. Step Settings
Sets the spacing between amplitude scale
lines in the graph display.
Set step values are also used as spacing for
the amplitude set with the triangle buttons in
the maximum and minimum amplitude settings
of Items (C) and (D) above.
11. Q Indication Button
Used to switch the filter point’s Q indication
method.
The following three methods are available:
(1) Numerical indication
Q values are indicated by a numerical figure.
(2) Oct/band fractional indication
The value of the octave bandwidth
corresponding to the Q value is indicated by a
fractional value.
(3) Oct/band numerical indication
The value of the octave bandwidth
corresponding to the Q value is indicated by a
numerical figure.
Example: When the Q value is 4.318
Numerical indication: 4.318
Oct/band fractional indication:
1/3 oct/band
Oct/band numerical indication:
0.333 oct/band
12. Grouping Button
Sets grouping within the ARC box.
On ARC measurement completion, the measurement
target ARC boxes are automatically grouped,
cancelling already-set grouping on any of these
boxes, if there was. Actual operation filter data,
measurement parameters, and the filter data
created by ARC measurement are interlocked
among the grouped ARC boxes.
