8.1.2 Internal BERT Configuration
The Internal Bert Configuration allows you to configure the BERT chip (if enabled) to generate spe-
cific patterns and error rates. Normally, the error rate is left at None, but the BERT pattern can be
transmitted with a known error rate to confirm other test equipment accuracy.
8.1.2.1 Loopback Configuration Settings
You can change configurations at any time.
To update the BERT configuration:
Select configurations for patterns & error rate.
Click Update BERT Config.
