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.
