Explanation
Center Wavelength
The setting range is 600.000 to 1700.000 nm.
If you press the COARSE key you can use the rotary knob or arrow keys to change the
numerical value in 1 nm steps. The value changes in 0.1 nm steps if you do not press the
COARSE key.
Start Wavelength
The setting range is 50,000 to 1700.000 nm.
Stop Wavelength
The setting range is 600.000 to 2250.000 nm.
Note
• When the start or stop wavelength is set, one wavelength becomes fixed, and this changes
the value of the sweep width. In addition, the center wavelength value is also changed at the
same time.
• Changing the center wavelength does not change the sweep width.
AUTO CENTER OFF/ON
This key sets whether the PEAK→CENTER soft key functions for each sweep.
When this key is set to ON, the peak is searched in the active trace waveform and set
as the center wavelength automatically for each sweep. The active trace must be set to
WRITE. When ON is selected,
at the bottom of the screen is displayed in reverse
video.
One-Action Keys
This is the general name for a key that uses data from the active trace waveform (the
currently displayed waveform) to set measurement conditions.
Setting conditions requires that a waveform is displayed for the active trace.
PEAK →CENTER
Sets the wavelength of the peak value to the center wavelength.
After execution, the center wavelength set in the center wavelength setting screen is
displayed. The center frequency can be changed after the setting is made initially.
MEAN WL→CENTER
Sets the average of two wavelengths falling below the threshold value (3 dB) from the
waveform peak of the active trace to the center wavelength. The center wavelength can
be changed after the setting is made initially.
VIEW→MEAS
This key is used to set the currently set ZOOM scale (ZOOM CENTER, ZOOM SPAN,
ZOOM START, ZOOM STOP) as the measurement scale (CENTER, START, STOP,
SPAN).
When you press this key, the current waveform display scale is set as the measurement
scale for the next sweep.
