CTA CTA Process Models & Execution

Question 1

Which NI-supplied TestStand process model is most appropriate for a single-operator, single-UUT manufacturing station?

Accepted Answer

Sequential

Answer

Parallel

Answer

Batch

Answer

LabVIEW Parallel

Question 2

In the TestStand Batch process model, what distinguishes a 'Master' thread from a 'Test Socket' thread?

Accepted Answer

The Master thread coordinates batch flow while Test Socket threads run per-UUT tests

Answer

Master threads run on a separate PC

Answer

Test Socket threads have higher priority

Answer

Master threads cannot call sub-sequences

Question 3

What TestStand mechanism allows a process model to pause all test sockets until every socket reaches a synchronization point?

Accepted Answer

Rendezvous

Answer

Semaphore

Answer

Event

Answer

Notification

Question 4

Which callback in the TestStand process model is executed once before any UUT is tested, making it ideal for fixture initialization?

Accepted Answer

PreBatch

Answer

PreUUT

Answer

Setup

Answer

MainSequence

Question 5

A CTA architect wants the process model to prompt the operator to reseat a UUT upon failure and allow a retest. Which feature enables this?

Accepted Answer

Limit Test retry count property

Answer

Automatic retry loop in PostUUT callback

Answer

TerminateOnFail = False flag

Answer

Test Socket restart command

Question 6

In the TestStand Parallel process model, how is the number of concurrently running test sockets typically controlled?

Accepted Answer

Through the 'Number of Test Sockets' setting in the process model sequence

Answer

By the number of CPU cores detected

Answer

By the station license count

Answer

Automatically by Windows thread scheduler
