reference values.

In the Advanced menu there are two parameters to configure the fibre optical
test. They are:
Threshold Attenuation: It defines the maximum difference that can exist

between the reference signal with the highest power level and the
reference signal with the lowest power level. Any signal out of this range
will be deleted and not used as a reference signal during the measurement
process.
Max. Attenuation: It defines the attenuation level used by the field meter

to display the status message on screen. If the attenuation level is below
this value the status message will be "PASS" and if it is above this value
the status message will be "FAIL".
i.3 Selective Optical to RF Converter
Description
►
The selective optical to RF converter has a filter that separates each wavelength
and directs it to an independent circuit with a photosensor, which obtains the RF
signal that carries. The RF signal obtained for each wavelength passes to a band
switch.
The band switch receives a signal and converts it to a frequency within the RF
band (65 — 2150 MHz). In the case of a terrestrial / cable signal the signal is
not converted since that signal is within the RF range. After the conversion, the
RF signal output is connected to the analyzer input connector and the
measurement is performed in the usual way to an RF signal. In the conversion,
bear in mind that for every unit of optical attenuation (one dB), occurs two dBs
of power loss in RF. As an example, every 3 dB of optical attenuation for each
splitter are equivalent to 6 dB of power loss for RF.
