Cyclic Acquisition Process
MTS MultiPurpose TestWare® Data Acquisition Process Descriptions 313
Acquisition tab
Store Data At Displays which cycles or segments the process collects data on.
Note The entire list of cycle numbers may not be displayed.
If the Data Storage Pattern is User Defined, you must type the cycles or
segments you want to collect data on. Segments must be defined as a list of
positive integers. Cycles can be defined as a list of positive integers or integers
and half cycles (1.5).
Store Data For Specifies how many cycles or segments the process acquires data for when it
detects a cycle in the Store Data At list.
You can select from 0.5 (one segment) to 1000 cycles. The default value is 1.0
cycle.

Acquisition Method Specifies how data is acquired.
Timed—acquires data at a user-specified time interval.
Level Crossing—acquires data when the selected Level Crossing signal
changes a specific amount.
Interleaved Timed and Level Crossing—acquires both Timed and Level
Crossing data.
Peak/Valley—acquires data when a peak or valley is detected in the specified
Peak/Valley signal.
Time Between Points Specifies the time interval at which the process acquires data.
Note MPT may change the number you enter slightly to reflect the resolution
of your system clock rate. For instance, if you type in “0.003” (3
milliseconds) and press the Enter key, the number may change to
“0.0029.”
Level Crossing Signal Selects the signal the process monitors for level changes.
Level Crossing
Increment Specifies how much the signal must change before the process acquires data.
