Frequency Range
6.2.2.14.
The Frequency Range parameter defines the input frequency in the Ku, C or L bands.
This parameter affects the displayed frequencies and ranges of the ProView 2900 DVB-S2
receiver parameters. The following figure illustrates the Frequency Range screen.
1 1 1 1
2 2 2 2
3 3 3 3
Available frequency band options are:
L BAND – selects the frequency range 0.950000 - 2.150000 GHz
•
Ku BAND - selects the frequency range 3.200000 - 4.200000 GHz
•
C BAND - selects the frequency range 10.700000 - 12.750000 GHz
•
Frequency Scan
6.2.2.15.
The Frequency Scan configuration function sets scanning a selected frequency range if the
stream's frequency is unknown. The symbol rate must be known and set in the
ProView 2900. The ProView 2900 scans the frequency range, while seeking a valid DVB
stream. Upon locating a valid DVB stream, the ProView 2900 marks the located frequency
and service name. Results output either to the RS-232 port (terminal) or Telnet. The following
screen displays the Frequency Scan screen
NOTE
The ProView 2900 scans only the L-band frequency range. Located frequencies are shown in
L-Band and must be modified for the relevant frequency value if they are tuned to either C-
band or Ku-band.
