Tunable Laser Source 55
Adjusting Your Unit According to Wavelength
7. To exit the Setup menu, press Setup.
Note: The difference between the pre-selected wavelength and the measured
wavelength cannot be greater than ± 0.200 nm or ± 0.0250 THz.
This user-performed calibration feature can help you achieve better
absolute wavelength accuracy if, for example, you feel that conditions
outside the unit may have affected the calibration.
The difference between the pre-selected wavelength and the measured
wavelength cannot be greater than ± 0.200 nm. If the difference between
the measured and preselected wavelengths is greater than ± 0.200 nm
(for example, if you have entered the wrong value), an error message will
be generated.
IMPORTANT
Note that the offset introduced into the Tunable Laser Source with
this software feature cannot be disabled. To correct for a handling
error during the procedure, you must repeat the steps described
above with a calibrated wavelength meter.
