A bit error rate tester (BERT), also known as a bit error ratio tester 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:
- Pattern Generator, which transmits a defined test pattern to the 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.

Famous quotes containing the words bit, error and/or rate:
“This dog and man at first were friends;
But when a pique began,
The dog, to gain some private ends,
Went mad and bit the man.”
—Oliver Goldsmith (1730?–1774)
“Children, then, acquire social skills not so much from adults as from their interactions with one another. They are likely to discover through trial and error which strategies work and which do not, and later to reflect consciously on what they have learned.”
—Zick Rubin (20th century)
“Unless a group of workers know their work is under surveillance, that they are being rated as fairly as human beings, with the fallibility that goes with human judgment, can rate them, and that at least an attempt is made to measure their worth to an organization in relative terms, they are likely to sink back on length of service as the sole reason for retention and promotion.”
—Mary Barnett Gilson (1877–?)
