6.16.7 Test, Int' BERT, MODE Menu

Test, Internal BERT, Mode Menu
The test mode may be one of the following:
The BERT mode is fixed in
the results of the BER test at the user defined Autolog period. In Autolog mode
the screen above is not shown, but rather a warning "Cannot select 1
Min/Manual mode while AUTOLOG of PRBS results is active (YES)" is
displayed. To be able to manually select the BERT mode auto-logging of the
BER result must be disabled by either setting the Autolog period to zero (Main,
Log, Autolog) or by clearing the flag requesting it to log the BERT results on the
subsequent Autolog screen.
One Minute sliding window mode displays the average BER over the last 1
minute. It does this by storing the error results second by second in a circular
table 60 entries long and recalculating the average BER each second. For any
seconds where the BERT is `out of sync` a zero entry is made in the table. The
average BER over the one minute period is calculated based on only the non-
zero entries (when sync is recovered).
Manual mode allows the operator to manually start, stop & restart tests which
may run for up to 27 hours (99,999 seconds), at which point the results are
frozen.
