■ [ANALYSIS MODE]
: Set the analysis mode.
This sets the analysis processing method (analysis mode) for the measurement data.
○ Setting method
< List operations (confirming) >
• CH1/CH2
: Analyze the CH1 measurement data (ratio) with the CH2 measurement data as the
reference.
• CH2/CH1
: Analyze the CH2 measurement data (ratio) with the CH1 measurement data as the
reference.
• CH1
: Use the CH1 measurement data (amplitude) as it is. The phase is insignificant.
• CH2
: Use the CH1 measurement data (amplitude) as it is. The phase is insignificant.
For more information on the analysis mode, refer to " 5.1 Analysis mode ".
■ [PHASE RANGE]
: Set the phase display range.
This sets the display range for the phase.
○ Setting method
< List operations (confirming) >
• ±180°
: Display phase in the range − 180°
≦
θ < + 180°.
• 0 to +360°
: Display phase in the range 0
≦
θ < + 360°.
• −360 to 0°
: Display phase in the range − 360
≦
θ < 0°.
• UNWRAP
: Phase unwrapping mode.
■ [PHASE RANGE]
–
[APERTURE]
: Set the number of data items (aperture) for the moving average.
This sets the number of moving average phase data points (number of frequency measurements) for
obtaining the group delay characteristic. Although this affects the display of the group delay, it does not
affect the display of phase. The group delay characteristic is smoother when the aperture is increased, but
sudden changes are not observed.
○ Setting method
< Numerical value settings (immediate setting) > , < Numerical value settings (new input) > ,
< Numerical value settings (edit) >
The setting range is the even values from 2 to 200 and the setting resolution is 2.
