Bit Errors
Number of received pattern bits that have a value
opposite that of the corresponding transmitted pattern
bits since initial pattern synchronization. For example,

bit errors occurred.
Bit Err
Rate
Ratio of pattern bit errors to received pattern bits since
initially acquiring pattern synchronization.
Bit Err Sec
Number of seconds during which one or more pattern
bit errors occurred since initial pattern synchroniza-
