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:
“Scarlett O’Hara: Oh, oh, Rhett. For the first time I’m finding out what it is to be sorry for something I’ve done.
Rhett Butler: Dry your eyes. If you had it all to do over again, you’d do no differently. You’re like the thief who isn’t the least bit sorry he stole, but he’s terribly, terribly sorry he’s going to jail.”
—Sidney Howard (1891–1939)
“When we do not know the truth of a thing, it is of advantage that there should exist a common error which determines the mind of man.... For the chief malady of man is restless curiosity about things which he cannot understand; and it is not so bad for him to be in error as to be curious to no purpose.”
—Blaise Pascal (1623–1662)
“At the rate science proceeds, rockets and missiles will one day seem like buffalo—slow, endangered grazers in the black pasture of outer space.”
—Bernard Cooper (b. 1936)
