Agilent 86038B Photonic Dispersion and Loss Analyzer, Second Edition
Specification: describes a guaranteed product performance that
is valid under the specified conditions. Specifications are based
on a coverage factor 1 of 2 (unless otherwise stated),
corresponding to a level of confidence of >95%.
Typical value: a characteristic describing the product
performance that is usually met, but not guaranteed.
Generally, all specifications are valid after warm-up, at the
stated operating conditions and measurement settings, in
swept-wavelength measurement mode.
Absolute wavelength uncertainty
Specifies the maximum difference between displayed and actual
wavelength. Displayed wavelength refers to the wavelength
associated with a point in the measurement result.
Wavelength is defined as wavelength in vacuum.
Conditions:
"Stepped mode"
sweep mode)" as specified. Other conditions as specified.
Chromatic dispersion (CD)
The derivative over wavelength of the
equivalently, of the "Relative group delay (rGD)"
expressed in ps/nm.
Chromatic dispersion (CD) uncertainty
Specifies the uncertainty of the measurement results for
"Chromatic dispersion (CD)"
difference between the measured value and actual value.
Conditions: as specified.
Measurement: The specification is derived from the
