BERT or bit error rate test is a testing method for digital communication circuits that uses predetermined stress patterns consisting of a sequence of logical ones and zeros generated by a test pattern generator.
A BERT typically consists of a test pattern generator and a receiver that can be set to the same pattern. They can be used in pairs, with one at either end of a transmission link, or singularly at one end with a loopback at the remote end. BERTs are typically stand-alone specialised instruments, but can be Personal Computer based. In use, the number of errors, if any, are counted and presented as a ratio such as 1 in 1,000,000, or 1 in 1e06.

“I have given my pain a name and call it “dog”Mit is every bit as faithful, every bit as nosey and shameless, every bit as entertaining, every bit as clever as any other dog—and I can boss it around and vent my bad moods on it, just as others do with their dogs, servants, and wives.”
