This section covers additional error messages that may occure when working with
the Serial BERT.
Overheat Protection
The Serial BERT is equipped with an overheat protection function to prevent it from
overheat damage.
If the temperature of the error detector or pattern generator exceeds a certain
threshold, the Serial BERT displays the following warning message, respectively:
N O T E
The temperature level is not yet critical. However, the Serial BERT may be damaged
if operation is continued. The message is intended to inform you to take the
appropriate measures. Save your current instrument settings, shut down the Serial
BERT and let it cool down before operating it again.
If the Serial BERT is operated at this state for a longer time, the temperature may
reach a critical level. In this case, the following message is displayed:
