The long-term wavelength repeatability can be obtained by taking the
NOTE
wavelength repeatability and wavelength stability into account.
The smallest selectable wavelength increment or decrement.
Specifies the change of the actual wavelength of the tunable laser source
over time, expressed as ± half the span between the maximum and
minimum of all wavelengths.
Conditions:
Time span as specified, uninterrupted tunable laser source output power,
constant wavelength and power level settings, constant temperature.
Other conditions as specified.
Using a wavelength meter, averaging time
