DETAILED DEM O DUL ATOR STATUS
This screen shows the estimated Eb/No. This is the co mpo s ite Eb/No including framing overheads (as used
by INTELSAT when specifying modem performance figures). The BER is the final USER BER which is
being passed to the customer. The Offset is the measured error of the received carrier, relative to the
nominal position expected which is useful for determining the frequency drift due to the satellite and
frequency conversion equipment. The Level is the level of the desired carrier estimated by the
demodulator and is only shown if the Monitor/AGC option is fitte d. From this s creen the Down Arrow leads
back to the selected Status screen.
