A5.4.3 Configuration for the selective optical to RF converter
After the connection is made, the user can use the equipment for measurement
of optical signals as if they were
RF signals. Steps to measure a signal are as
follows:
Press the Settings key and select the corresponding band, whether
terrestrial (for optical link) or satellite (for optical LNB). In the case of
a satellite optical signal and frequency tuning, user has to select the
signal type, characterized by the band (low/high) and the type of
polarization (vertical/horizontal). In the case of a satellite optical
signal and channel tuning, the parameters are defined by the channel
(refer to the Settings menu section for more details).
Select the
Optical module option and press the joystick.
It appears a window to enable the optical module and to configure
additional parameters.
Select
Enable .
At the top right area of the screen appears the OPT icon meaning
there is external power.
It appears a window with some setting parameters.
Figure A5.7.
In this window appears the level power for each wavelength and also the user
can set two parameters:
►
Wavelength :
Wavelength selection at the RF output by the user among the three
wavelength available: 1310, 1490 and 1550 nm.
►
Attenuator :
When the attenuator is ON is 15 dB RF attenuation. When the attenuator is
OFF is 0 dB RF attenuation. The attenuator must be adapted to the installation
according to the RF power (modulation index).
Also, on the right side appears the selective power in dBm for each wavelength.
