PRBS BER Test

The PRBS BER Test collects the bit error rate data using PRBS pattern. The test is performed to ensure that the cable meets the required specifications.

Setup

  1. PRBS polynomial

  2. Test duration

Method

  1. Enable PRBS pattern on TX ports.

  2. Clear counters.

  3. Measure PRBS BER on each SerDex lane of each RX ports.

  4. Report the time-series data of the PRBS BER
