4.2.4 Auto Sync setting (Auto Sync)
Set measurement method when sync loss detected during measurement.
With this function set to On, measurement is stopped when synchroniza-
tion is lost and restarts measurement when re-synchronization is estab-
lished. All counters are cleared at this time.
When set to Off, measurement continues without establishing
re-synchronization. However, if sync-loss occurred, Sync Loss lamp does
not go on.
Select “Auto Sync” on the main menu screen to perform setting.
Sync loss occurs when the MP8931A detects 6 error bits out of 64 bits.
If the measurement object is a signal of the lower error rate than that of
sync loss condition at Auto Sync On, the measurement may not be per-
formed due to alternative repeating of sync loss and sync gain at burst
error.
