one single frame error. In contrast to this, the Serial BERT loses pattern
synchronization and must re-synch before the test can be continued. Currently,
the detection mechanism for loss of synchronization is a high error ratio. This
causes the Serial BERT to show many errors in the "Accumulated Results"
window though there was only one single error. The serial BERT shows with
such DUTs high error number, the number is not accurate. The Auto Resync
Counter events are shown in the Accumulated Results window and the same
are logged in file. Log settings can be changed in Error Detector's Accumulation
Setup dialog.
