Agilent Technologies 81642A Stud Sensor User Manual


 
Definition of Terms Specifications
Agilent 81480A and 81680A, 40A, 82A, 42A, & 89A Tunable Laser Modules Users Guide, Sixth Edition 47
NOTE The specified signal-to-total-SSE ratio is also applicable to output
powers higher than the specified values.
Wavelength Range
The range of wavelengths for which the specifications apply.
Wavelength Repeatability
The random uncertainty in reproducing a wavelength after detuning
and re-setting the wavelength. The wavelength repeatability is ± half
the span between the maximum and the minimum value of all actual
values of this wavelengths.
Conditions: uninterrupted TLS output power, constant power level,
temperature within operating temperature range, coherence control
off, short time span.
Measurement with wavelength meter at high power output. Averaging
time given by wavelength meter, 1 s.
NOTE The wavelength repeatability of Output 1, the Low SSE Output, of the
Agilent 81680A/40A Tunable Laser modules is the same as the relative
wavelength accuracy of Output 2, the High Power Output (guaranteed
by design).
NOTE The long-term wavelength repeatability can be obtained by taken the
wavelength repeatability and wavelength stability into account.
Wavelength Resolution
The smallest possible displayed wavelength increment/decrement.
Wavelength Stability
The change of wavelength during given time span, expressed as ± half
the span between the maximum and the minimum of all actual
wavelengths.
Conditions: uninterrupted TLS output power, constant wavelength
and power level settings, coherence control off, temperature within ±1
K, time span as specified.
Measurement with wavelength meter. Averaging time given by
wavelength meter,1 s.
