Pattern Sync
This field displays the current state of pattern sync during a test. If no test is in
progress, NO TEST is displayed. If a test is active, but the receiver is not in
pattern sync, NO SYNC is displayed. If the receiver is in pattern sync, IN SYNC
is displayed.
Elapsed Time
Displays the amount of time elapsed since a timed test began or, if completed, the
total test time.
Bit Errors
Displays the total number of bit errors detected since the test began or since error
statistics were cleared (up to a maximum number of 999,999).
Errored Seconds
This field displays the number of asynchronous errored seconds that have been
detected since the test began or since error statistics were last cleared. This
parameter includes errored seconds and sync loss seconds.
% EFS
This ratio is derived from the number of error free seconds divided by the number
of seconds accumulated in Elapsed Time.
