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 1/2 Turbo and non-Turbo), [coder
rate], 3/4 (QPSK 3/4 Turbo and non-Turbo), 7/8

Only).
mmmm.mmm = Data rate in kHz.

Note: Setting the modulator rate turns off the RF
transmitter.
