Result Description
Bit Error Rate The ratio of pattern bit errors to
received pattern bits since initially
acquiring frame synchronization.
NOTE: This ratio is determined using
only the bits in the payload of the
frame.
Bit Errored Seconds The number of seconds during which
one or more pattern bit errors occurred
since initial frame synchronization.
Bit Errors A count of the number of received bits
in a recognized pattern that do not
match the expected value since initially
acquiring frame synchronization.
Error-Free Seconds A count of the number of error-free sec-
onds during which error analysis has
been performed since initial pattern
synchronization.
Error-Free Seconds
% Number of error-free seconds divided
by the number of seconds during which
error analysis has been performed
since initial pattern synchronization,
expressed as a percentage.
Total Bits The total number of bits received since
initial frame synchronization.
