Response to Query
Tx BPSK Data
Ordering
TBO= 1 byte, value of 0
or 1
Command or Query.
Invert Transmit BPSK Data Ordering, where::
0=Standard
1=Non-Standard
Example: TBO=1 (selects Inverted BPSK Ordering)
TBO =
TBO?
TBO*
TBO#
TBO? TBO=x
(see Description
of Arguments)
Tx Clock Invert TCI= 1 byte, value of 0
or 1
Command or Query.
Invert Transmit Clock, where:
0=Normal
1=Inverted
Example: TCI=1 (selects Inverted TX Clock)
TCI =
TCI?
TCI*
TCI#
TCI? TCI=x
(see Description
of Arguments)
Tx Clock
Source
TCK= 1 byte Command or Query.
Tx Clock Source, where:
x=Tx Clock Source:
0=SCT
1=Tx Terrestrial
Example: TCK=1 (selects Tx Terrestrial Clock Source)
TCK=
TCK?
TCK*
TCK#
TCK? TCK=x
(see Description
of Arguments)
Tx
Reed-Solomon
Code Word
TCW= 1 byte, value of 0
to 5
Command or Query.
Tx RS encoding, where:
0 = RS(225,205,10)
1 = RS(219,201,9)
2 = RS(208,192,8)
3 = RS(194,178,8)
4 = RS(126,112,7)
5 = RS(220,200,10)
Depending on Modem mode, overhead type, and data rate, not all selections will be
valid.
Example: TCW=0 (This is a ‘don’t care’ if RS is Off under TRS)
TCW=
TCW?
