Power range
Specifies the range from the smallest input power that causes a
significant change of the measured (displayed) power to the highest
power for which the specifications apply if not differently stated.
Measurement: The lower limit corresponds to half the "Noise pp
(dark)" (see, "Noise pp (dark)" on page
Power setting mode
Operating mode where the user sets the desired output power. The
power control function of the attenuator automatically adjusts the
attenuation to get the set output power (see also,
mode" on page 60).
Range in attenuation setting mode
Attenuation range that can be set at the attenuator in the Attenuation
Setting Mode and for which the specifications apply (if not differently
stated).
Range in power setting mode
Range of optical output power that can be set at the attenuator in the
Power Setting Mode and for which the specifications apply (if not
differently stated).
The actual minimum value is determined by the optical input power minus the
maximum attenuation.
