Definition of Terms Specifications

Agilent 81600B Tunable Laser Source Family, Fourth Edition 37

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 7 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.

Attenuation

The nominal attenuation of the output power selected using the built-in

attenuator.

The absolute wavelength accuracy of the low-SSE output

(if applicable) is the same as the absolute wavelength accuracy of the high

power output (guaranteed by design).

NOTE

Applicable only to Tunable Laser Source modules that include a built-

in attenator.
