Usage: Useful in cases where the user doesn’t want to shut down for one condition
but wants to monitor quality and read conditions.
Definition: Applies

Output 1
.
With
Trend Analysis
, the user can track the occurrences and frequency of
mismatches, No-Reads, and the number of reads per trigger, and output the
results to any of three outputs.
Example: Trend Analysis Mode = No-Read
Trigger Evaluation Period= 25 triggers (read cycles)
Number to Output On = 4
In this example, the reader will activate an output when 4 No-Reads occur
within a period of 25 triggers (read cycles).
