Executing LIMITEST ON compares trace data to the line parameters stored in the LIMIT HI and LIMIT LO arrays. As before, during single-sweep mode, LIMITEST ON compares the limit line to trace A data only. Executing LIMITEST OFF erases the LIMIT HI and LIMIT LO trace arrays. Use the STOR command to save trace array contents in a le. Below, the LIMIT HI trace array is stored as a trace le called \LIMIT."
500 OUTPUT 723;"STOR T,$LIMIT$,LIMIT_HI;"
The limit-line test fails when trace-data amplitude is greater than the upper test limit or less than the lower test limit. Use LIMIFAIL or LIMIBEEP to signal test-limit failures. Use the marker and math commands to analyze trace data. For example, executing SUB TRB,TRB,LIMIT_HI stores the dierence between the upper test limit and the trace B data. Execute MKPK HI;MKWL? of the signal that failed the test limit by the largest amount.
