Enter frequency plan
Typically every country has its own regulations concerning the frequency plan, i.e. the channel locations
and the channel widths. That is what we call a country–specific frequency plan. Table 2–12 shows the
frequency plan of "Bavaria''. This plan applies to all cable TV networks of Bavaria. Hence, there is no
information about the programs included yet, as this information depends on the (local) operator of a
particular network. In the first step, we merely want to enter this frequency plan with the Cable TV
Measurements option and call this channel table "EXAMPLE BAVARIA''.
Table 2–12: Frequency plan example of channel table "EXAMPLE BAVARIA''
Channel No. Band name Start frequency in MHz Width in MHz
2 VHF 1 50.5 7
21 UHF 474 8
22 UHF 482 8
23 UHF 490 8
24 UHF 498 8
1. Press the MENU key.
2. Press the Channel Setup softkey.
3. Press the New softkey to create a new channel table.
4. In the Name field, enter EXAMPLE BAVARIA as channel table name with the keypad, and press
ESC.
5. In the Description field, enter in the same way EXAMPLE FOR COUNTRY SPECIFIC
FREQUENCY PLAN.
6. To enter the first channel (line 2 of Table 2–12):
Use the knob or the cursor keys to move to the No. column of the existing channel.
Enter 2 for the channel number.
Enter VHF 1 as Comment.
Set the Modulation Standard to < unused >.
Therefore RF represents the center frequency and can be calculated as
RF = Start + Width / 2 = 50.5 MHz + 7 MHz / 2 = 54 MHz.
Set the RF frequency to 54 MHz.
Set the channel Width to 7 MHz.
7. To enter the second channel (line 3 of Table 2–12):
Move down to focus the last channel.
Press the Copy Channel softkey to copy the last channel.
Move down to the copied channel.
Set the channel number No. to 21.
Enter UHF as Comment.
Set the Modulation Standard to < unused >,
i.e. RF = 474 MHz + 8 MHz / 2 = 478 MHz.
Set the RF frequency to 478 MHz.
Set the channel Width to 8 MHz.
