c. Output menu
The next standard menu shows the frequency
or output channel , the level control and the
selection of output spectrum inversion .
OUTPUT
Ch:C21
(474.000MHz)
Lev:99 Norm.
OUTPUT
Freq: 474.00
Level: 99
Output:Norm.
To change a parametre, press key until the
desired parametre starts fl ashing. Then you can
change its value by means of keys and .
The output frequency range is 46 to 862 MHz
The output level control allows values between 00
and 99.
The available output values are:
• Norm Normal Output Mode
• CW Continuous Wave Mode. A continuous
carrier is generated in the output
frequency selected (useful for balancing
the headend in the absence of an input
signal).
• OFF No output is generated.
• NULL QAM output modulation with null
packets only
d. Services menu
This menu shows the list of transport stream
services selected. Each time the user selects a new
input transport stream, the unit performs a search
for services.
During the process, the unit will show the message
below displaying the number of channels as soon
as they are being found:
SERVICE
Scanning: 13
Once the search has completed, a list of services is
displayed with the following information:
SERV 10125
2/8 18/25
France 2
OFF
It is indicated the service order number as well
as the total number of services in the
multiplex
(the fi gure indicates that the 2nd service out of
8 services, is available), the statistics (18/25) and
the service name. In the processing mode (see
Versions menu) it is shown if the user has selected
it to: either
remove its encryption from the output
(OFF) by means of a module CAM (DCY), or to pass
through without modifi cation (ON).
Statistics information is the following: fi rst number
indicates the percentage of the output occupied
by the displayed service;
second number indicates
the free percentage at the output.
In the example:
• Service “La2” would occupy the 18% of the
output (since it is set OFF, means that it is being
eliminated)
• There is a 25% of free room.
• So we can easily see that, in principle, this
service could be activated (ON or DCY), since
there is still suffi
cient capacity at the output.
The free capacity percentage at the output is
only updated once recorded the confi guration
of services.
Additionally, on the upper right corner of the
window it is indicated the status of the service
(scrambled or plain) at the input and at the
oputput:
Service scrambled at the input and at
the output.
Service scrambled at the input and
plain at the output.
Service scrambled at the input.
If the service is set to OFF (removed) shows the
service identifi er (service_id) in decimal format.
In the transparent mode ((see Versions menu) it is
not possible neither eliminate nor decode services,
so no changes are allowed on this menu.
