tips
• The FBS filter stored in the Preset Memory cannot be recalled even when changing the Preset Memory while
the FBS function is ON. The FBS filter currently in operation remains active and unchanged.
• The FBS filter point for which guard function is not set to "Yes" will be cleared when the M-864D is powered
on.
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.
12. Q Indication Button
Used to switch the FBS filter’s Q indication.
The following 3 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 figure.
(3) Oct/band numerical indication
The value of the octave bandwidth corresponding
to the displayed Q value is indicated by a
numerical figure.
Example: When the Q value is 69.249
Numerical indication: 0.021
Oct/band fractional indication:
1/48 oct/band
Oct/band numerical indication:
69.249 oct/band
13. Minimum amplitude adjustment Button
Sets the minimum amplitude for the graph display.
(Sets the lower limit of the graph.)
The downward pointing triangle button reduces
the amplitude and the upward pointing triangle
button increases the amplitude.
