Response to
Command
Query
(Instruction
Code and
Qualifier)
Response to Query
Rx BERT State BRX= 1 byte, value of 0
or 1
Command or Query.
Rx BERT State, where:
0=Off
1=On
Example: BRX=1 (Rx BERT On)
BRX=
BRX?
BRX*
BRX#
BRX? BRX=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 Buffer
Programming
Mode
RBM= 1 byte, value of 0
or 1
Command or Query.
Rx Buffer Programming Mode, where:
0 = Buffer Size is programmed in Bits.
1 = Buffer Size is programmed in milliseconds.
Note: Commands as well as queries are not allowed when either the GigaBit
Ethernet or NP card has been selected as the current interface type.
Example: RBM=0
RBM=
RBM?
RBM*
RBM#
RBM? RBM=x
(see Description
of Arguments)
Rx BPSK Data
Ordering
RBO= 1 byte, value of 0
or 1
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 Buffer Size RBS= 8 bytes Command or Query.
Rx Buffer Size (in either bits or milliseconds, see RBM command), where:
xxxxxxxx=Rx Buffer Size
Note: Commands as well as queries are not allowed when either the GigaBit
Ethernet or NP card has been selected as the current interface type.
Example: RBS=00000512
RBS=
RBS?
RBS*
RBS#
RBS? RBS=xxxxxxxx
(see Description
of Arguments)
ReCenter Buffer RCB= None Command only.
Forces the software to recenter the receive Plesiochronous / Doppler buffer.
Note: This command is not allowed when either the GigaBit Ethernet or NP card has
been selected as the current interface type.
Example: RCB= (ReCenter buffer)
RCB=
RCB?
RCB*
RCB#
N/A N/A
