Definition of Terms Specifications
Agilent 81600B Tunable Laser Source Family, Fourth Edition 43
Conditions: Uninterrupted tunable laser source output power, constant power setting,
constant temperature. Other conditions as specified.
Power linearity
When measuring the ratios (in dB) between the displayed power level and
the actual power level for different output power levels of the tunable laser
source, the power linearity is ± half the difference between the maximum
and the minimum value of all ratios.
Figure 12 Power linearity.
Conditions: Uninterrupted tunable laser source output power, constant wavelength
setting, constant temperature. Other conditions as specified.
Power repeatability
The uncertainty in reproducing the power level after changing and re-
setting the power level. The power repeatability is ± half the span
between the highest and lowest actual power.
Conditions: Uninterrupted tunable laser source output power, constant wavelength
setting, constant temperature. Other conditions as specified.
The long-term power repeatability can be obtained by taking the
power repeatability and power stability into account.
