Modulation Menu - Motorola DSR-4550 Operator's Manual

Modulation Menu

Note: This menu is not available when the ASI In option is selected. That option is
located in the Manual Tune menu (described on page 18).
This menu, together with the Manual Tune menu, allows the user to initially
acquire a DigiCipher II signal. Press the  buttons until the Modulation menu
appears. Press the ENTER button to continue.
When either the DCII-MAN, 8PSK (Phase Shift Keying Modulation with
turbocodes), or DVB-MAN, the user must additionally specify a Symbol/Code/
Format combination.
Mode Field
Press the 4 button until the cursor is at the Mode label, and press the ENTER
button to move into the field. Press the  buttons to display the options:
DCII-AUTO, DCII-MAN, 8PSK (Phase Shift Keying Modulation with
turbocodes), or DVB-MAN. Select a mode and press ENTER to exit the field.
Note: In any of the non-auto modes [i.e., DCII-MAN, DVB-MAN (both manual
modes) or 8PSK (Phase Shift Keying Modulation with turbocodes)], the DSR-4550
only searches for a signal that matches what is set in the Symbol/Code/Format field.
If DCII-AUTO is selected, the DSR-4550 searches through all available combina-
tions to acquire a signal, and then remains parked on a signal once it is acquired.
