Read the first 6 CTA Process Models & Execution flashcards as text

  1. Which TestStand execution flag prevents an operator from manually stopping a test once it has started, ensuring data integrity?

    Answer: Operator Privileges → Deny Abort

    Setting Operator Privileges to deny the Abort action prevents operators from interrupting a running test, protecting data integrity.

  2. What happens in TestStand when a sequence is called with 'Run Modes' set to 'Skip' on a particular step?

    Answer: The step is bypassed and marked as skipped in the result

    A step with Run Mode set to Skip is bypassed without execution, and TestStand records it as skipped in the result data.

  3. In a TestStand Parallel process model, what is the purpose of the 'Test Socket Synchronization' step group?

    Answer: It ensures all sockets complete setup before any socket begins testing

    The Test Socket Synchronization step group uses rendezvous or semaphores to hold all sockets at a barrier until every socket is ready to proceed.

  4. A CTA architect needs to implement a process model for a station where different UUT types require completely different test sequences. Which approach is recommended?

    Answer: Use a routing step in the process model that selects a sequence file based on UUT type

    A routing step in the process model reads the UUT type (e.g., from a barcode scan) and dynamically loads the correct sequence file for that unit.

  5. Which TestStand property specifies how many times a failed UUT can be retested before being permanently marked as failing?

    Answer: UUT Retry Count in the process model

    The UUT Retry Count parameter in the process model controls the maximum number of times a failing UUT will be re-run before receiving a final FAIL status.

  6. What is the significance of the 'Cleanup' subsequence in a TestStand process model?

    Answer: It is always executed regardless of pass/fail to release resources safely

    The Cleanup subsequence is guaranteed to execute even after a failure or abort, ensuring hardware resources are safely released and the station is left in a known state.
