Number of checked data bits/data blocks.
Number of error bits/errors
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.
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:SETup:MCOunt"
and ":BERT:SETup:MERRor" has been reached, or the measurement has
been stopped by the command ":BERT:STOP".
0 = Measurement has not been terminated.
Status of clock line.
1 = Clock line active.
0 = Clock line not active.
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.
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.
'queries the result of the bit error rate measurement.
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.
