2k mode: 1512 carrier for user data (total 1705 carriers)

Code rate

During a transmission data can be lost or changed. To recover this data, a re-
dundancy is added to the signal which is to be transmitted (forward error correc-
tion). The factor of the quantity of redundancy contained in the bits transmitted is
called code rate.

Using the setting "

C7/8

" you can get the highest output data rate at lowest re-

dundancy.

• Use the

buttons to place the cursor under "

C…

".

• Set the code rate required using the

buttons ("

C1/2

", "

C2/3

",

"

C3/4

", "

C5/6

", "

C7/8

").

Guard interval

In this menu item you set the relation of the duration of the user symbols to the
duration of the guard intervals to be transmitted. A high guard interval, e.g.
"

G1/4

" causes a low output data rate. For cable networks the setting "

G1/32

"

is adequate.
