2.2.7.3.2 P25 receiver tests
P25 receiver tests are performed with the R8100 in Generate or Duplex mode and protocol specific tests
are accessed with the PROJECT 25 soft key - see Figure 3.2.8.4.2-1. The R8100 can generate various
P25 compliant test patterns using C4FM modulation – see Figures 3.2.8.4.2-2. Test patterns that yield an
audio tone can be heard in the receiver of the radio under test. Others can be used in conjunction with the
radio manufacturers’ RSS to perform BER testing and alignment. A means is provided to change the
Network Access Code (NAC) and edit the P25 V oice Frame to adapt to the system under test.
