Signal Constellation Graph
7.4.2.3 Time-based Graphs
A number of time-based graphs can be displayed. These update approximately once per
second but actual refresh rate will depend upon the Ethernet connection speed and
channel loading. Graphical values are stored for 31 calendar days or until the modem is
powered down. The recording of all values occurs automatically at all times once the
modem is powered on and is not dependent on whether the graphs are being viewed or
not.
All of the results can be retrieved from the modem (perhaps for use in quality reports)
using one of the remote interfaces – see the ‘
Remote M&C Specification for Quantum
and Evolution Series Satellite Modems
’ for more details. In fact, remote control
commands can be used to start the automatic recording of any parameter within the
modem, whether or not these are supported as graphs on the web interface.
The web interface supports display of the following time-based graphs:
•
The modem received signal Eb/No.
•
The Eb/No of the distant modem being controlled via AUPC.
•
The modem received power level.
•
The modem final (user) BER after error correction (estimated from the FEC).
•
The modem actual BER from the internal BER Tester (available as a Test
function).
•
The transmit power level while under AUPC control.
