Related to display
Parameter Default Setting Range Unit Description
DISPLAY TYPE ABSOLUTE
ABSOLUTE
RELATIVE
DRIFT(MEAS)
DRIFT(GRID)
-
Setting of the format to display wavelengths,
levels, noises, and SNRs, which are the results of
analyses.
ABSOLUTE: display of absolute values
RELATIVE: display of relative values
compared to GRID.
DRIFT(MEAS): display of drift values by using
wavelengths measured previously
as references.
DRIFT(GRID): display of drift values by using the
grid wavelengths as references.
CH RELATION OFFSET
OFFSET
SPACING
-
Setting of the format to display wavelengths
between channels and level relative values during
DISPLAY: ABSOLUTE.
This parameter is valid only when DISPLAY is set
to ABSOLUTE.
OFFSET: Display of offset values by using one
arbitrary channel as the reference.
SPACING: Display of offset values compared to
an adjacent channel
REF CH HIGHEST
HIGHEST
****
-
Setting of the reference channel when CH
RELATION is set to OFFSET.
This parameter is valid only when DISPLAY is set
to ABSOLUTE and also when CH RELATION is
set to OFFSET.
HIGHEST: A channel at the highest level is used
as the reference.
****: A ****th channel is used as the
reference.
MAX/MIN
RESET
- - -
If pressed, MAX/MIN is RESET.
Button valid only when DISPLAY is set to DRIFT
OUTPUT
SLOPE
OFF ON/OFF -
ON/OFF of the function to obtain the least square
approximation line of the channel peak.
POINT
DISPLAY
ON ON/OFF -
ON/OFF of the function to display the data range
used for fitting into the waveform window.

Parameter Default Setting Range Unit Description
SIGNAL
POWER
PEAK
PEAK
INTEGRAL
-
Setting of the signal power calculation method
PEAK: Peak level value
INTEGRAL: Level value per calculation of integral.
INTEGRAL
RANGE
10 10 to 999 GHz
Setting of the integral range for determining the
signal power
Valid when the SIGNAL POWER setting is
INTEGRAL. If the set value is Δ f, the integral
is calculated in the range of channel center
wavelength ±Δ f.
