Definition of Terms 3
Absolute wavelength accuracy (continuous sweep mode)
The maximum difference between the
“Logged wavelength“ and the actual
wavelength in “Continuous sweep mode“. Wavelength is defined as
wavelength in vacuum.
Figure 14 Absolute wavelength accuracy (continuous sweep mode)
Conditions: As specified. No mode-hop.
Absolute wavelength accuracy (stepped mode)
The maximum difference between the displayed wavelength and the actual
wavelength of the tunable lase source. Wavelength is defined as
wavelength in vacuum.
Conditions: Constant power level. Other conditions as specified.
Measurement: Using a wavelength meter, averaging time
≥ 1s.
Dynamic power reproducibility (continuous sweep mode)
Specifies the random uncertainty in reproducing the output power at the
same actual wavelength in different sweeps. It is expressed as ± half the
span between the maximum and minimum of all actual output powers.
