Return values:
string
Value 1
Numer of checked data bits/data blocks
Value 2
Number of error bits/errors
Value 3
Error rate. If no termination criterion has been reached since the
beginning of the measurement, the current quotient of "Number of
error bits/errors" and "Number of data bits/data blocks" is entered.
As soon as at least one final result has been reached in continuous
measurement, the most recent final result is entered.
Value 4
Status of measurement.
1 = Measurement has been terminated, i.e. the number of data
bits/data blocks or error bits/errors preset by the commands
BERT|BLER:SETup:MCOunt and
BERT|BLER:SETup:MERRorhas been reached, or the
measurement has been stopped by the command
BERT|BLER:STOP.
0 = Measurement has not been terminated.
Value 5
Status of clock line
1 = Clock line active
0 = Clock line not active
Value 6
Status of data line
1 = Data line active (only clocked data is detected; if the clock
signal is missing, a data change is also not detected).
0 = Data line is not active.
Value 7
Synchronization status
1 = The measurement is synchronized, i.e. the clock and data lines
are active and the "Number of error bits/errors" to "Number of data
bits/data blocks" ratio is better than 0.1, so that the measurement
ratio can be assumed to be realistic.
0 = The measurement is not synchronized.
<Result>
BERT:RES
queries the results of the bit error rate measurement.
Response: "1000,5,5E-4,1,1,1,1"
The measurement has been terminated, and synchronization has
been performed. Out of 1000 data bits, 5 error bits were measured,
yielding an error rate of 0.005.
