==Bit error rate tester==
A bit error rate tester (BERT), also known as a "bit error ratio tester"<ref>{{Cite web|url=https://www.electronics-notes.com/articles/radio/bit-error-rate-ber/testing-bert.php|title=Bit Error Rate Testing: BER Test BERT » Electronics Notes|website=www.electronics-notes.com|access-date=2020-04-11}}</ref> or ''bit error rate test solution'' (BERTs) is electronic test equipment used to test the quality of signal transmission of single components or complete systems.

The main building blocks of a BERT are:
* [[Digital pattern generator|Pattern generator]], which transmits a defined test pattern to the [[Device under test|DUT]] or test system
* Error detector connected to the DUT or test system, to count the errors generated by the DUT or test system
* Clock signal generator to synchronize the pattern generator and the error detector
* Digital communication analyser is optional to display the transmitted or received signal
* Electrical-optical converter and optical-electrical converter for testing optical communication signals
