Specifications MN/SNM1001L.IOM
A–5
A.5 L-Band Modulator Specifications
A.5.1 Digital Data Rate
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 to 2500 kHz.
