Note
For Maximum Bit rate the maximum modulation index is 0.5.
2.4.3. FSK/OOK Mode Receiver
All receiver tests are performed with RxBw = 10 kHz (Single Side Bandwidth) as programmed in RegRxBw, receiving a
PN15 sequence. Sensitivities are reported for a 0.1% BER (with Bit Synchronizer enabled), unless otherwise specified.
Blocking tests are performed with an unmodulated interferer. The wanted signal power for the Blocking Immunity, ACR,
IIP2, IIP3 and AMR tests is set 3 dB above the receiver sensitivity level.
