Rx ModCod and Local Es/No (ModCod / Local Es/No) – Two pieces of data are graphed
in time synchronous manner:
o The left side of the graph has a vertical key of Rx ModCod (blue).
o The right side of the graph has a vertical key of Local Es/No (red).
The Local Es/No is the Es/No of the local modem. When more than one ModCod is
received in the smallest interval period allowable by the graph, the most common
ModCod received in that time interval is displayed.
•
Rx Capacity Configuration Parameters – This is a graphical representation of some of
the common configuration settings that can affect user data rate, and typically do not
change:
o Pilots On or Off
o Normal Block or Short Block
o Symbol Rate
These parameters are shown to provide you with a more complete representation of user
capacity, when looked at in conjunction with the other graphs provided on these pages.
substantially less than the terrestrial rate of the user traffic due to the effect of
the compression card.
