Example 3497A Configurations 603COUNTER ASSEMBLY INTERRUPT CONDITIONSMEASUREMENT COMPLETE(CE slot#,l set)Return after a Dl slot# command = 1Count DownZero Counts Reached.PeriodIPulse Width(CF slot#,3 thru 6)Completed Measurement Available.OVERFLOW(CE slot#,2 set)Return after a Dl slot# command = 3Count Up(CF slot#, 1 )PeriodIPulse Width(CF slot#,3 thru 6)>999999 Counts in Counter.Input period exceeds maximummeasurement time for range used.Also, for each mode of operation, a level change output is available at the OUTPUTHI terminal of the counter assembly for Measurement Complete or Overflow, whetheror not the counter is enabled for interrupts to the 3497A.CONFIGURATIONTo illustrate interrupt examples, the counter is configured as shown in Figure 199with an open collector input. Note that the level change output shown is availablewhenever Measurement Complete or Overflow conditions occur.Artisan Technology Group - Quality Instrumentation ...
