NB20 system adopts the latest RF technology, providing very high adjacent channel rejection ratio and anti-blocking performance, which gives rise to the outstanding anti-jamming capability of the new system. NB20 receiver can detect the frequency and amplitude of EMI interference with unbeatable accuracy and precision based on the extremely low self-noise of -125dBm. The RF performance of NB20 system surpasses the older 4047 systems several orders of magnitude. Furthermore, NB20 system...
