Bit Error Rate Measurements - BERT Block
Displays the current number of occurred errors.
Remote-control command:
BERT:RES?
Response (the 2nd value indicates the number of occurred errors):
"1000, ,5E-4,1,1,1,1"
5
Displays the termination criterion for the measurement.
These criteria can be entered to keep the duration of the
measurement short for low as well as high bit error rates.
The last measurement result is displayed after the measurement has
been terminated.
Remote-control command:
BERT:RES?
Response (the 4th value indicates whether the measurement has
been terminated: 1 = terminated): "1000,5,5E-4,
The measurement was manually terminated by the
User
user switching the state to off.
Remote-control command:
BERT:STAT OFF
BERT:STOP
The measurement was terminated because the
Number of Data
specified number of data bits was reached.
Bits
The measurement was terminated because the
Number of
specified number of errors was reached.
Errors
Displays the status of the measurement.
This enables the user to check whether the measurement functions.
The status of the data and clock lines and of the synchronization is
checked and displayed.
If a faulty status is displayed, the signals can be checked at the BERT
interface using an oscilloscope.
Remote-control command:
BERT:RES?
Response (the 4th value indicates whether the measurement has
been terminated: 1 = terminated): "1000,5,5E-4,
The applied clock signal was detected.
Clock
Remote-control command:

Response (the 5th value indicates the status of the
clock line: 1 = active, 0 = not active):
