How to increase sample period using ADN2915 PRBS Generator?

Hello,

 

We are using the ADN2915 PRBS Generator to drive and test our photoreceiver (LabBuddy).

 

We are operating at 10Gbps to test the eye diagram as the manual suggests, but no graph is generated when we connect the output DATA pin from the PRBS Generator to the input DATA pin on the Error Detector side.

 

Also, when we press "Read Error" on the software, it either outputs a 0 or 255, but doesn't give us any number in between. So we were wondering if there is any way to increase the duration of error sampling so we can observe the error count change continuously.

 

Thank you!
