E–4
E.3.3 Status Items
Status items are not strictly part of the Statistics but are important items used for
monitoring for current conditions.
E.3.4 BER Testing
Allows selection of ModCod for test.
BER Test Result
Test results – continuous. PN data is generated in the Framer (Fig. G-1 Block 6) and recovered in
the Deframer (Fig. G-1 Block 5).
E.3.5 ACM Modulator Status
Currently active Tx ModCod.
E.3.6 ACM Demodulator Status
Currently active Rx ModCod.
Es/No of local demodulator.
E.3.7 CnC Status
CnC PSD Ratio
Power Spectral Density (PSD) ratio at local end.
PSD = Interferer - Distant, density (dB).
CnC Ratio (Power)
Power Ratio at local end.
CnC Ratio = Interferer - Distant, power (dB).
∆F between Interferer and Distant carriers.
Round trip delay of Tx carrier in ms (measured in Fig. G-1 Block 8).
