Symbol/Code/Format Field Default: Mode-Dependant

Note: This field is not available when the DCII-Auto option in the Mode field is

selected.

The Symbol field (in Msps) defines the symbol rate at which the unit attempts

acquisition when the selection for acquisition mode is either DCII-MAN, 8PSK-TC

or 8PSK-DVBS2, or DVB-MAN. The Code field defines the forward error

correction (FEC) coding using an internal Viterbi decoder for convolutional code

rates. The Format field defines the waveform modulation format (i.e., QPSK,

OQPSK, etc.) associated with the selected modulation mode.

The Format The Symbol/Code/Format field has the following options, depending

upon the Mode field selection.

Symbol Rate Options:

• DCII-MAN: 3.25, 4.88, 7.32, 9.76, 11.71, 14.63, 19.51 (default), and 29.27

• 8PSK-TC or 8PSK-DVBS2: Range 01.000000 (default) to 30.000000

• DVB-MAN: Range 00.000000 (default) to 99.999999

Code Options (for all modulation modes): 5/11, 1/2, 3/5, 2/3, 3/4, 4/5, 5/6, and 7/8

Format Options: DCII-QPSK, DCII-OQPSK, DVB-QPSK, and 8PSK

Press the

button until the cursor is at the Symbol label, and press the ENTER

button to move into the menu. Press the

buttons to display the options. Using

the

buttons, scroll through the various Symbol/Code/Format combinations and

select the required combination by pressing the ENTER button to return to top menu.

Port Menu

Note: This menu is not available when the ASI In option is selected. That option is

described in "Manual Tune Menu" (described on page 16).

The Port menu is available when the Manual Tune input setting is one of the

L-band ports (RF Input) as described in the "Manual Tune Menu" (described on

page 16).

In order to use virtual channels, one or more ports must be associated with a

particular satellite and polarity. These menus allow the user to associate the satellite

and polarity with L-band Port 1 through Port 8. Press the

buttons until the

Port menu appears (shown below).
