Definition of Terms Specifications

Agilent 81600B Tunable Laser Source Family, Fourth Edition 49

Measurement: Using an optical powermeter and by performing repeated spectral loss

measurement on a stable absorption peak from a reference component,

then analyzing the variation of the determined (interpolated) wavelength of

the peak.

Wavelength repeatability (stepped mode)

The random uncertainty in reproducing a wavelength after changing and

re-setting the wavelength. The wavelength repeatability is ± half the span

between the maximum and the minimum of all actual values of this

wavelength.

Conditions: Uninterrupted tunable laser source output power, constant power level,

constant temperature. Other conditions as specified.

Measurement: Using a wavelength meter, averaging time

≥ 1s.

Wavelength resolution

The smallest selectable wavelength increment or decrement.

The wavelength repeatability of the low-SSE output

(if applicable) is the same as the wavelength repeatability of the high

power output (guaranteed by design).

The long-term wavelength repeatability can be obtained by taking

the wavelength repeatability and wavelength stability into account.
