2.1.10.1 Digital Data Rate
The digital data rate (Table 2-8) is selectable in 1 bit/s steps. The symbol rate is
automatically calculated on the programmed data rate. Data rates entered that exceed the
data rate or symbol rate specification are rejected at entry.
The symbol rate range is 4.8 to 2500 ks/s.
