Modulation Fidelity (NXDN™ Zone display)
Modulation Fidelity (FSK error) represents how accurate a transmitter reproduces an ideal theoretical
modulation waveform. The measurement is performed by first removing frequency error and symbol
deviation gain error from the received signal then computing the RMS difference between the deviation
of the resulting signal at each symbol decision point and the ideal deviations of those symbols; there
should be no bit errors. On the R8100 this is reported as an RMS error in % relative to the mean deviation
across symbols.
RAN (NXDN™ Zone display)
Radio Access Number is a 6-bit field for the NXDN conventional system protocol of the RTCH/RDCH
frame in the SACCH field. The R8100 analyzes all NXDN transmissions regardless of the transmitted
number. See Generate mode Receiver Tests for more details.
BER (NXDN™ Zone display)
See BER Test.
