CTA CTA Configuration & Station Settings 2 — Questions and Answers
Question 1: Which TestStand configuration item maps a named step type (e.g., 'NI_Wait') to its underlying implementation DLL or VI?
- Type Palette (.ini)
- Adapter mapping in Station Options
- Step type definition in the type palette file (Correct answer)
- Module search path entry
Correct answer: Step type definition in the type palette file
Each step type definition in the TestStand type palette file specifies the adapter, module path, and function name that implements the step.
Question 2: A CTA architect wants TestStand to automatically reconnect to a VISA instrument if the connection drops mid-test. Where is this best configured?
- In the VISA alias file
- In the sequence file with a retry loop around instrument open calls (Correct answer)
- In the NI-VISA configuration utility only
- In Windows Device Manager
Correct answer: In the sequence file with a retry loop around instrument open calls
Adding a retry loop around the VISA resource open call in the sequence file is the recommended way to handle transient instrument disconnections.
Question 3: What is the role of the TestStand 'Workspace' file (.tsw)?
- It stores encrypted station passwords
- It groups related sequence files, type palette files, and project files for organized development (Correct answer)
- It compiles sequences into executables
- It configures the TestStand license server
Correct answer: It groups related sequence files, type palette files, and project files for organized development
A TestStand Workspace file organizes related sequence files, type palettes, and supporting project files into a single logical development environment.
Question 4: Which TestStand setting controls the default measurement units (e.g., milliseconds vs. seconds) displayed in numeric step results?
- Unit Preferences in Station Options
- Number Format in step properties (Correct answer)
- LabVIEW front panel scaling
- VISA unit mapping
Correct answer: Number Format in step properties
The Number Format property on individual step types controls how numeric values, including their units, are formatted and displayed in results.
Question 5: A CTA architect is deploying TestStand to a PC without the full TestStand development environment. Which installer type is required?
- TestStand Full Development Environment
- TestStand Run-Time Engine (Correct answer)
- NI Package Manager only
- LabVIEW Runtime Engine only
Correct answer: TestStand Run-Time Engine
The TestStand Run-Time Engine provides only the execution components needed to run deployed sequences, without the sequence editor or development tools.
Question 6: Which TestStand Station Options section configures how the operator interface (UI) is launched when the station application starts?
- Operator Interface Options (Correct answer)
- Report Options
- Adapter Settings
- Execution Startup Mode
Correct answer: Operator Interface Options
Operator Interface Options in Station Options specify which operator interface application is launched at startup and how it connects to the TestStand engine.
