Bit Error Rate Performance With Noise

Refer to the following tables for BER performance over the specified data rate ranges.
The table values reflect specified guaranteed performance of the demodulator when
operating with the associated modulator and noise. Typically the performance shall be 0.5
dB better than specified for adequate production margin.
