Description of Arguments
Query
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
Query only.
Read the total number of Bit Errors.
Example: ERR = 9999999
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
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)
