Wavelength repeatability (continuous sweep mode)
Keysight N777-C Series Tunable Laser Family User's Guide
The ratio of signal power to total spontaneous emission power within,
expressed in dB. The total spontaneous emission power is measured over
the specified
Figure 24
Conditions:
Output power as specified. Other conditions as specified.
Using an optical spectrum analyzer, by integrating the source
spontaneous emission and excluding the remnant signal. For the low-SSE
output, if applicable, with a fiber Bragg grating inserted between the
tunable laser source and the OSA to suppress the signal, thereby
enhancing the dynamic range of the OSA.
The range of wavelengths for which the specifications apply (if not
otherwise stated).
The random uncertainty of the nominal wavelength of the tunable laser
source at any fixed actual wavelength in repeated sweeps. The nominal
wavelength of the tunable laser source is derived from the (discrete)
