Tx
ModCod
and
Remote
Es/No
(ModCod
/
Rem
Es/No)
–
This
graph
is
particularly
useful
when
the
modem
is
running
is
ACM
mode
as
it
maps
the
remote
Es/No
of
the
far
end
modem
synchronously
along
with
the
near
side
(local)
Tx
ModCod
used.
Note
that
two
pieces
of
data
are
graphed
in
time
synchronous
manner:
o
The
left
side
of
the
graph
has
a
vertical
key
of
Tx
ModCod
(blue).
o
The
right
side
of
the
graph
has
a
vertical
key
of
Remote
Es/No
(red).
In
this
format,
the
graph
depicts
changes
in
ModCod
that
occur
when
the
reported
Remote
Es/No
meets
the
Es/No
trigger
points
to
switch
up
or
down.
Note
that
the
Remote
Es/No
is
the
“reported”
Es/No
of
the
far
end
modem
as
seen
by
the
local
modem.
This
reported
Remote
Es/No
data
can
be
250ms
to
400ms
old
as
this
is
the
amount
of
time
it
can
take
for
this
data
to
traverse
the
satellite
link
for
processing
by
the
local
modem.
When
more
than
one
ModCod
is
used
in
the
smallest
interval
period
allowable
by
the
graph,
the
most
common
ModCod
used
in
that
time
interval
is
displayed.
•
Tx
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.
