The status is unknown. This can occur if accumulation has not been started,
or if Burst Sync mode has not been activated.
•
Burst Sync Ratio
Percentage of time in burst (while the Gate In signal is low) that patterns are
in sync and error counting is active. A higher percentage is desirable, because
it indicates that more data is measured during each burst.
•
Total Burst Count
Total number of bursts received while in burst mode during the accumulation
period.
•
Bad Burst Count
Total number of bursts where sync is never achieved during the accumulation
period.
•
Bit Count
The number of bits considered for the accumulation period is displayed here.
This may not equal the total number of bits sent from the PG.
