(Instruction &
Qualifier)
Response to Query
BERT Results
All: Total Bit
Errors, Total
Number Of
Bits and
average BER
N/A 23 or 15 bytes 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: <0/BRA?
RESPONSE EXAMPLE 1: >0000/BRA=1.0E+03:2.2E+06:1.0E+03 (No Demod Lock)
RESPONSE EXAMPLE 2: >0000/BRA=1.0E+03:2.2E+06 (No Sync)
N/A BRA? BRA=x.xEx:y.yEy:z.
zEz

of 0 or 1
Command or Query.
Sets or returns Tx BERT state in the form x, where:
0 = off
1 = on
EXAMPLE: <0/BTX=1 (BERT On)
BTX=

BERT Pattern
Sync
N/A 1 byte, value
of 1 or 2
Query only.
Returns the BER Test Pattern Sync Status in the form x, where:
1 = pattern sync
2 = no pattern sync
N/A RPS? RPS=X

Arguments)
Rx Baseband
Frames
discarded
N/A Query only.
Returns the Rx baseband frames received without errors, but discarded due to the required feature code
not having been purchased. Returns two entries separated by a colon:
First entry = 16 APSK frames discarded
Second = 32 APSK frames discarded.
