USER'S MANUAL PROLITE-67
a)
Wavelenght at which measurements are taken.
b)
Absolute power loss of the signal at the corresponding wavelenght. It
represents the measurement of the power loss or signal attenuation in dB.
c)
Status of the signal with respect to attenuation threshold level, whose value is
defined in the menu "Setup". If you see the sign "X" it means that the signal
exceeds the threshold level. If you see the sign " " it means that the signal
does not exceed the threshold level.
d)
The OLT led indicates the status of the OLT signal with respect to the ATTEN.
THRESHOLD value defined in the Configuration Menu. Three indicator light
colours are possible and each colour represents its status signal with respect
to this attenuation threshold value. They are GREEN (when all signals are
below the attenuation threshold value), AMBER (when some signal are above
the attenuation threshold value) and RED (when all signals are above the
attenuation threshold value).
To capture all reference values, press
the three reference values will be captured simultaneously at three wavelenghts.
To make or consult a data register, refer to the section LOGGER Function.
4.2.4 OPTICAL LOSS TEST SET Function
This function measures signals in a simultaneous and selective way at three
wavelengths through selective filters for each band emitted by a test source (e.g.
PROLITE-105). It is equivalent to the previous one but it has more options such as
absolute measures and measurement with respect to the threshold value. Reference
values can be taken individually for each wavelength.
