Bit Error Rate basics | Bit Error Rate Tester

This page covers Bit Error Rate basics and mentions Bit Error Rate Tester from Tektronix. Other vendors of Bit Error Rate testers are also mentioned.

Bit Error Rate is the ratio of number of received erroneous bits to total number of bits transmitted.
BER = Bits in error/Total bits
There are various methods to determine bit error rate. The most robust among them is to determine quality of received bits using eye diagram. This technique is employed by most of the Bit Error Rate Testers.
