BERT:SETup:MERRor

0.0 ... 2^32-1

Enters the number of errors to occur before the measurement is terminated. This termination
criterion always terminates the measurement after the specified number of errors. Starting from this
point, the fourth value is output with 1 (= terminate measurement) if the measurement result is
queried with

:BERT:RES?

.

Example:

BERT:SET:MERR 1E4

'sets a measurement over 1000 errors.

BERT:SETup:RESTart:STATe

ON | OFF

Activates/deactivates an external restart of the BER measurement.

Parameters:

ON

The reset signal for the BER measurement is fed via the

Restart

input of

the BERT interface.
If the PRBS sequence cannot be continued uninterruptedly, the BER
measurement must be stopped at the end of the data sequence and
subsequently restarted at the beginning of the new data sequence. The
measurement is stopped and started via a 0-1-0 slope of the

Restart

signal. A transition from logic 0 to 1 causes a partial result to be generated
and the measurement to be stopped. A transition from 1 to 0 starts the
measurement for the next subinterval. This measurement is synchronized
anew. If the instrument is used as a data source, a signal in which a single
1 was coded at the end of the data sequence can be used as a restart
signal at the instrument marker output. This causes the BER measurement
to stop briefly at the end of the data sequence and start again.
Partial results (number of data and error bits) are added up until the
predefined total number of data or error bits is reached or exceeded.
The measurement is reset by

Pattern Ignore

or

Data Enable

, regardless

of its status.

OFF

The reset signal for the BER measurement is generated internally. This
setting is suitable for PRBS sequences that run continuously and thus
ensure uninterrupted repetition.

Example:

BERT:SET:REST:STAT ON

'the external signal restarts the measurement.
