Explanation
WL SHIFT **.**nm
This key is used to set the wavelength shift.
When the wavelength shift is changed, the set value is added to the display value on
the wavelength axis. This key is used for purposes such as correcting differences in
wavelength display values among different measurement instruments.
The setting range is -5.000 to 5,000 nm. Settings can be adjusted in steps of 0.001 nm.
The value changes in steps of 0.1 nm if you press the COARSE key.
When setting the wavelength shift amount,
is displayed at the bottom of the screen
in inverse video.
LEVEL SHIFT***.***dB
This key is used to set the level shift.
When the level shift is changed, the set value is added to the display value on the level
axis.
This key is used for purposes such as correcting level errors due to differences in the NA
values of 9.5/125 μm SM optical fibers connected to the instrument, and correcting loss
on externally connected isolators, filters and the like.
The setting range is -60.00 to 60.00 dB. Settings can be adjusted in steps of 0.01 dB.
The value changes in steps of 0.1 dB if you press the COARSE key.
When setting the wavelength shift amount,
is displayed at the bottom of the screen
in inverse video.
