units are later changed, the start and stop wavelength units will change accordingly.
Note that a start wavelength limit in nm will become a stop wavelength limit if THz
or cm
is chosen. See

The wavelength limit can be useful when laser modulation causes spurious wave-
lengths to be displayed. Reducing the wavelength range to the region of interest
minimizes the number of spurious wavelengths displayed. Also, the graphical dis-
play uses these start and stop wavelength values to plot the power spectrum, whether
the wavelength limit function is on or off.
Preset will turn the wavelength limit on and will set the start wavelength to 1200 nm
and the stop wavelength to 1650 nm.
To limit the wavelength range
1 Press the Setup key.
2 Press the WL LIM softkey.
3 Press the LIM ON softkey if it is not already highlighted.
4 Press the STARTWL softkey to adjust the start wavelength value.
5 Press the STOP WL softkey to adjust the stop wavelength value.
