Return values:
<Result> string
<data bits/data blocks>
Numer of checked data bits/data blocks
<errors>
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.
<measurement status>
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:MERRor
has been reached, or the mea-
surement has been stopped by the command
BERT|BLER:STOP
.
0 = Measurement has not been terminated.
<clock detected>
Status of clock line
1 = Clock line active
0 = Clock line not active
<data detected>
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 mea-
surement ratio can be assumed to be realistic.
0 = The measurement is not synchronized.
Example: 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.
Usage: Query only
