Specifications
C.3 Demodulator Specifications
C.3.1 Digital Data Rate
Refer to Table C-4.
The digital data rate is selectable in 1 bit/s steps. The modem automatically calculates
and sets the symbol rate. Data rates entered that exceed the data rate or symbol rate
specification are rejected at entry.
The symbol rate range is 4.8 kHz to 2.5 MHz.
