Description Setting
Specify the increments at which cycles are stored per decade. Blocks/Cycles per
Decade
(Logarithmic)
Cycle counts are divided into logarithmic decades, which are in factors of 10 (for
example 10, 100, 1000, and so on). The application divides the number of cycles
in the decade by the number of Cycles per Decade to determine the increments
at which it can reference the cycles in the decade.
For example, if 10 is specified and the test is 105 cycles long, the total number
of cycles would span into the third decade. In the first decade, the cycle increments
are 1 (10/10 =1), which equates to cycles 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. In the second
decade, the cycle increments are 10 (100/10=10), which equates to cycles 10,
20, 30, 40, 50, 60, 70, 80, 90, 100. In the third decade, the cycle increments are
100 (1000/10=100), which equates to cycle 100. The test is over before the next
increment.
Specify the increments at which cycles are stored over the entire activity. Every nth
Block/Cycle
(Linear)
For example, if 10 is specified and the test is 105 cycles long, cycles 10, 20, 30,
40, 50, 60, 70, 80, 90, or 100 could be shown or acquired.
Specify a series of cycle numbers to store. Each cycle number must be separated
by a space. Designate Specific
Blocks/Cycles
Select a variable that the activity will monitor to initiate a data block save. The
data block is saved when the Change Criteria Threshold is reached. Block/Cycle
Change Criteria
Variable
Monitor a change in a selected variable, and then save block data when the
variable deviates by more than the specified Change Criteria Threshold amount.
You can select any numeric variable that is defined in the test or enter a numeric
value.
After the variable is selected, its dimension appears and allows you to specify
the Change Criteria Threshold.
The threshold value for the Block Change Criteria variable. The amount of change
can be specified with a numeric value for the shown dimension or with a variable. Change Criteria
