<ClockDetected> integer
Status of clock line.
1 = Clock line active.
0 = Clock line not active.
<DataDetected> integer
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.
<Synchronized> integer
1 = The measurement is synchronized, i.e. the clock and data
lines are active and the "Number of errors" to "Number of 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.
Example: BLER:RES?
queries the results of the block 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 blocks, 5 error bits were
measured, yielding an error rate of 0.005.
Usage: Query only
Manual operation: See "Bit Error Rate" on page 189
:BERT:RESult?
Queries the result of the last BER measurement. The response consists of seven
results separated by commas. In the first measurement following the start, intermediate
results for the number of data bits, error bits and error rate are also queried. In the fol-
lowing measurements (only for
BERT:SEQ AUTO
) only the final results of each single
measurement are queried
Note: At the end of a measurement, the restart of a new one is delayed until the first
measurement result has been queried with
BERT:RES
. The resulting brief measure-
ment interruption is irrelevant because the subsequent measurement will be synchron-
ized within 24 data bits.
Return values:
<NumDataBits> integer
Numer of checked data bits.
<NumErrors> integer
Number of error bits.
