Specifications Definition of Terms
48 Agilent 81600B Tunable Laser Source Family, Fourth Edition
Conditions: Output power as specified. Other conditions as specified.
Measurement: 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.
Mea surement princi ples are indicated . Alter native measurem ent principles of equal value are also accepta ble.
Wavelength range
The range of wavelengths for which the specifications apply (if not
otherwise stated).
Wavelength repeatability (continuous
sweep mode)
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)
“Logged wavelength”s by interpolation. The repeatability is expressed as
± half the span between the maximum and the minimum value of all
nominal values.

Conditions: As specified. No mode-hop.
