Where: nnnnn.nnnn = Frequency in MHz, 950.0000 to
1750.0000 in 100 Hz steps for non-terminal frequency
display.
For terminal frequency mode, the range will be
determined by the LO frequency and high/low Mix of the
ODU.
Note: When the modulator frequency is programmed, the
RF output is switched off.
Where: xxx = ON or OFF.
Where:
x = A, B, C, D, or V [preset designator].
nnnn = 1/2 (QPSK ½ Turbo and non-Turbo), [coder
rate], 3/4 (QPSK 3/4 Turbo and non-Turbo), 7/8
(QPSK 7/8), BP12 (BPSK ½), 8P23 (8PSK 2/3), OQ12
(OQPSK 1/2Turbo and non-Turbo), OQ34 (OQPSK
3/4 Turbo and non-Turbo), OQ78 (OQPSK 7/8), BPSK
(BPSK1/1 Turbo and non-Turbo), QPSK (QPSK 1/1
Turbo and non-Turbo), OQSK (OQPSK 1/1 Turbo,
and non-Turbo), 2144 (BPSK 21/44 Turbo Only),
B516 (BPSK 5/16 Turbo Only), and 8P34 (8PSK 3/4
Turbo Only).
mmmm.mmm = Data rate in kHz.
Burst Mode = nnnn= 1/2
mmmm.nnn = 19.2 or 57.6 kbps
Where: x = A, B, C, D, or V (preset designator).
Note: Setting the modulator rate turns off the RF
transmitter.
Where: mmmm.mmm = Data rate in kHz.
nnnn = 1/2 (QPSK ½ Turbo and non-Turbo), [coder
