Testing Signal Definitions
The timing diagram Figure 9-30, “Testing Signal Definitions,” shows the relationships between a trigger
event and the output signals at the BER MEAS END and BER TEST OUT connectors.
If a BER MEAS END signal stays high following a trigger event, the BERT measurement is in progress and
other trigger events are ignored. This state is stored in the status register and can be queried.
