Receiver:

    All receiver tests are performed withRxBw= 10 kHz (Single Side Bandwidth) as programmed inRegRxBw, receiving a PN15 sequence with a BER of 0.1% (Bit Synchronizer is enabled), unless otherwise specified. The LNA impedance is set to 200 Ohms, by setting bitLnaZininRegLnato 1. 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 nominal sensitivity level.
