4.5.4 RF Parameter Configuration
For Decoder modules with up-converter the configuration page will display an Upconverter
section as in Figure 44.
RF Frequency sets the modulation frequency of the service. It is possible to select from a set of
predefined frequencies (according to the selected RF Channel list), or alternatively by entering a
specific frequency in the text box.
The following up-converter configuration parameters can be changed:
RF Channel list Select which channel plan to use. The available options are ITU
(C.C.I.R), OIRT and User defined.
RF Frequency Sets the carrier frequency of the output. It is possible to select
from a set of predefined frequencies (according to the selected
RF Channel list), or alternatively by entering a specific frequency
in the text box.
RF Power Level Determines the power of the output signal. Power level boundary
values will depend on the Decoder module, and is shown by
hovering the mouse cursor over the text box.
RF Enable Enables the RF signal on the output. The RF output signal will be
turned off when this is not enabled.
AVCR This parameter adjusts the Audio carrier output level compared
to the video carrier output level. The resulting output level will be
the selected value down from the video carrier. Please note that
this is power and not amplitude. Nominal value and range will
depend on the Decoder module being configured.
VMD Video Modulation depth. This level can be adjusted from 80 to
90%. This parameter is only available for the HP RF Decoders.
Clipping Determines how video is clipped before modulation. Enabling
clipping result in video being clipped 5% above configured
modulation depth. Off means video is not clipped. This
parameter is only available for the HP RF Decoders.
CW mode Continuous Wave Mode. The output will be an un-modulated
video carrier with no audio carriers present. This parameter is
only available for the HP RF Decoders.
Fine level adjust Fine tune the output power level, see 4.5.4.1. This parameter is
not available for HP RF Decoders.
The decoder will perform an auto calibration of the power level to match the selected
power output level every time the system boots or a change has been applied to the
RF Frequency, the RF Power Level or the RF Enable.
4.5.4.1 Fine level adjust
This section is not applicable for HP RF Decoder modules.
