Arguments
for Command
(Note that all arguments are ASCII numeric codes from 48 to 57)
or Query
4 bytes Query only.
Returns the value of Eb/No in the form xxxx, where:
xxxx = value from 0 to 20 dB in 0.1 dB steps.
Notes:
Returns 99.9 if demod is unlocked.
For values greater than 20.0 dB, the reply will be EBN=+020
Example: >0001/EBN=12.3{CR}{LF} (sets Eb/No to 12.3 dB)
7 bytes Query only.
Returns the total number of Bit Errors.
Example: >0001/ERR=9999999{CR}{LF}
1 byte Command or Query.
Sets or returns the Rx Buffer Programming Mode in the form x,
where:
0 = Buffer Size is programmed in Bits.
1 = Buffer Size is programmed in milliseconds.
Note: Command and Queries are not allowed when either the GBEI
or NP Module has been selected as the current interface type.
Example: <0001/RBM=0{CR}
1 byte Command or Query.
Sets or rewturns the Invert Receive BPSK Data Ordering in the form
x, where:
0 = Standard
1 = Non-Standard
Example: <0001/RBO=1{CR} (selects Inverted BPSK Ordering)
