Available frequency range is:
• For Ku-Band L.O.: 8500000 to 13000000 [KHz]
• For C-Band L.O.: 5000000 to 6000000 [KHz]
6.2.2.14. Frequency Range
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.

• Ku BAND - selects the frequency range 3.200000 - 4.200000 GHz
• C BAND - selects the frequency range 10.700000 - 12.750000 GHz
6.2.2.15. Frequency Scan
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.
