A bit error rate tester (BERT) is also known as a “bit error ratio tester” or bit error rate test solution (BERTs). Its’ is electronic test equipment used to test the efficiency of signal propagation of single components or full systems.
The BERT ‘s main building blocks are:
- Pattern generator, which transmits to the DUT or test device a given test pattern
- Electrical-optical converter for evaluating optical transmission signals and optical-electrical converter
- A DUT or test system error detector to count errors caused by the DUT or test system
- The digital message analyzer is optional to display the signal received or sent.
