C. OPERATION OF ADAPTIVE PRE-CORRECTOR
5. ADAPTIVE PRE-CORRECTOR STATISTICS
The ‗Adaptive‘ pre-corrector block provides various statistics concerning the adaptive process when
dragged to and expanded in the lower half of the web service page.
Elapsed time, Current iteration: Displays the time elapsed for the ongoing iteration (data
collection and analysis) for the adaptive process. The elapsed time may accumulate continuously in
the event that the sense input is invalidated and thereby preventing successful data collection and
analysis.
Last turn-around time: Displays the recorded time consumption for the last completed iteration
(data collection/analysis/curve implementation). The iteration time may typically vary from less than
10 seconds up to about one minute depending on the signal characteristic and the type of adaptive
correction running. The shortest iteration time is noted when only the non-linear adaptive pre-
corrector is running. The iteration time is increased when the adaptive linear pre-corrector process
is running.
Linear clean run: Accumulated count of the number of times the adaptive system has discarded
the collected linear data set and initiated a new collection of data. Under normal conditions this
counter is ‗0‘.
Linear bad sense count: Accumulated count of the number of times the data collection from the
linear sense port has failed for reasons other than level out of range (typically due to application of
an invalid type of spectrum on the sense port). Under normal conditions this counter is ‗0‘.
Non-Linear clean run: Accumulated count of the number of times the adaptive system has
discarded the collected non-linear data set and initiated a new collection of data. Under normal
conditions this counter is ‗0‘.
Non-Linear bad sense count: Accumulated count of the number of times the data collection from
the non-linear sense port has failed for reasons other than level out of range (typically due to
application of an invalid type of spectrum on the sense port). Under normal conditions this counter
is ‗0‘.
