Response to
Query
Rx BERT
Sync Loss
Threshold
BTH= 1 byte Command or Query.
Rx BERT Sync Loss Threshold, where:
0=Low
1=Medium
2=High
Example: BTH=1 (Medium)
BTH=
BTH?
BTH*
BTH#
BTH? BTH=x
(see Description of
Arguments)
Rx Eb/No N/A 4 bytes Query only.
Returns the value of Eb/No, between 0 and 20 dB, resolution = 0.1 dB.
Returns 99.9 if demod is unlocked.
Example: EBN=12.3 (selects Eb/No = 12.3 dB)
For values greater than 20.0 dB, the reply will be: EBN=+020
N/A EBN? EBN=xxxx
(see Description of
Arguments)
Rx BERT
Errors
N/A 7 bytes Query only.
Read the total number of Bit Errors.
Example: ERR=9999999
N/A ERR? N/A
Rx BPSK
Data
Ordering
RBO= 1 byte Command or Query.
Invert Receive BPSK Data Ordering in the form x, where:
0=Standard
1=Non-Standard
Example: RBO=1 (selects Inverted BPSK Ordering)
RBO =
RBO?
RBO*
RBO#
RBO? RBO=x
(see Description of
Arguments)
Rx Clock
Invert
RCI= 1 byte Command or Query.
Invert Receive Clock in the form x, where:
0=Normal
1=Inverted
Example: RCI=1 (selects Inverted RX Clock)
RCI =
RCI?
RCI*
RCI#
RCI? RCI=x
(see Description of
Arguments)
Rx
Reed-
Solomon
Code Word
RCW= 1 byte Command or Query.
Rx RS encoding in the form x, 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: RCW=0 (This is a ‘don’t care’ if RS is Off under TRS)
RCW =
RCW?
RCW *
RCW #
RCW? RCW=x
