Demodulation Without Sub-Carrier; Table 19: Performance Limitation For Table 20: Performance Limitation For - Safran CORTEX CRT Quantum User Manual

3.3.1.2. Demodulation without Sub-Carrier

Demodulation capability is license dependent. According to the telemetry licenses installed in the machine,
maximum data bandwidth can be full, standard or restricted. Restricted bandwidth is the baseline configuration
for Cortex CRT SM01037242, standard bandwidth is the baseline configuration for Cortex CRT SM01037243.
Refer to annexe 5 to determine which configuration has been delivered.
Next tables give the maximum bit and symbol rates for high bandwidth telemetry chains without sub-carrier:
