SNM-1010L Data/Control Modem Revision 0
Specifications MN/SNM1010L.OM
The decoder has the ability to select whether I is the first bit or Q is the first bit in the
symbol word grouping for compatibility with any system. For standard mode Q is the
first bit.
• Viterbi (Standard/Non-Standard)
• Sequential (Standard/Non-Standard)
B.3.22.5 Deinterleaver (Reed-Solomon Codec)
The Reed-Solomon depth 8 deinterleaver is based on the IESS-310 specification for
8PSK and is adapted for QPSK/BPSK operation.
• Depth 8 (Closed Network).
B.3.22.6 Demodulator Spectrum Rotation
The operator selects normal or inverted spectrum for the Demodulator Input. As a goal
the demodulator automatically resolves frequency sense.
B.3.22.7 Receive Frequency
The range of the input spectrum is from 950 to 1750 MHz, in 100 Hz steps. This is
derived from the RF input frequency.
The actual value of offset from the programmed frequency is available to the operator on
the front panel as well as the remote port. The resolution of this value is 1 Hz. Monitor
accuracy is
± 0.01 PPM.
