trate the selectivity and image rejection. This measurement was done 6 dB above the sensitivity
level with a useful signal of 433.92 MHz/FSK/20 Kbit/s/±16 kHz/ Manchester with a level of
–106 dBm + 6 dB = –100 dBm. The figure shows to which extent a continuous wave signal can
surpass –100 dBm until the BER is higher than 10
be 59 dB higher than –100 dBm which is –100 dBm + 59 dB = –41 dBm.

(dBS) instead of the carrier (dBC).
