■ [GRID LINE STYLE]
: Set the grid lines.
This sets the grid line style.
○ Setting procedure
<List operations (immediate settings)>
・
BROKEN LINE
: Display a broken-line grid.
・
SOLID LINE
: Display a solid-line grid.
■ [PHASE RANGE]
: Set the phase display range.
This sets the phase display range.
○ Setting procedure
<List operations (immediate settings)>
・
±180°
: Display the phase within the range of −180°
≦
θ < +180°.
・
0° to +360°
: Display the phase within the range of 0°
≦
θ < +360°.
・ −360° to 0°
: Display the phase within the range of
−
360°
≦
θ < 0°.
・
UNWRAP : Display the unwrapped phase.
○ Functions of function keys
・
[+360°]
: Display the phase with 360° added.
・
[−360
°
]
: Display the phase with 360° subtracted.
(Supplementary explanation)
This function is valid when the phase display range is UNWRAP.
■ [APERTURE]
: Set the number of moving average data points (aperture).
This sets the number of moving average phase data points (number of frequency measurement
points) for obtaining the group delay characteristic. Although this affects the display of the
group delay, it does not affect the display of the phase. The group delay characteristic is
smoother when the aperture is increased, but sudden changes are not observed.
○ Setting procedure
<Numerical settings (immediate settings)>, <Numerical settings>
The setting range is the even values of 2 to 200 and the setting resolution is 2.
○ Functions of function keys
・
[EDIT]
: Set the aperture with the numerical input palette.
・
[MODIFY]
: Modify the aperture with the knob or cursor keys.
