Description of Arguments
Command or Query.
Set or return the PN loopback pattern type in the form x, where:
0 = 2^23-1
1 = Reserved
2 = Reserved
3 = Reserved
4 = Reserved
5 = 2047
6 = 2^15-1
Example: RBP=0 (default 2^23-1)
Command or Query.
Initialises the PN loopback functionality and sets the pattern type in the form x, where:
0 = 2^23-1
1 = Reserved
2 = Reserved
3 = Reserved
4 = Reserved
5 = 2047
6 = 2^15-1
Example: TBP=0 (default 2^23-1)
Command only.
Inserts a single error.
Command only
Clears the BER counters.
Query only.
Returns 3 values, with each parameter is separated by a colon, in the form x.xEx:y.yEy:z.zEz where:
x.xEx = total number of bit errors
yEy = total number of bits
z.zEz = value of the average BER or "No Sync" if no demod lock.
Example 1: BRA=1.0E+03:2.2E+06:1.0E+03 (No Demod Lock)
Example 2: BRA=1.0E+03:2.2E+06 (No Sync)
Command or Query.
Set or return Tx BERT state in the form of x, where:
0 = off
1 = on
Example: BTX=1 (BERT On)
