LabVIEW software engineers for automated test benches

LabVIEW software engineers develop test applications for product validation and production testing. Bring in a specialist when manual procedures need automation or an existing application cannot accommodate new test requirements.

• Application development: Structure VIs with state machines or queued message handlers, separating operator controls from test logic.
• Test sequencing: Implement acceptance limits and result logging in LabVIEW, with NI TestStand integration where sequence management is required.

Engineers can review existing code before extending it, so changes fit the application's architecture.

Automated test bench and instrumentation developers connect measurement hardware to LabVIEW applications. Their work covers driver integration and measurement validation, including checks for scaling errors and communication failures.

• Instrument control: Use NI-VISA and SCPI commands to control instruments over interfaces such as USB or Ethernet. Implement timeouts and recovery behavior.
• Data acquisition: Configure NI-DAQmx acquisition with appropriate sampling and triggering. Check channel scaling and synchronization against the measurement requirements.

Specialists can isolate faults between the application and connected hardware.

Use LabVIEW Real-Time and LabVIEW FPGA specialists when desktop execution cannot meet timing requirements. Engineers assess loop rates and I/O behavior before assigning functions to a real-time controller or FPGA target.

On compatible CompactRIO or PXI systems, they can implement deterministic control loops and synchronized acquisition. Work includes host-to-target communication and buffering, with explicit handling of missed deadlines. Hardware selection and timing validation remain tied to the actual test requirements rather than assumptions about achievable performance.

Keep established test applications maintainable as hardware changes and software dependencies age. LabVIEW maintenance engineers diagnose intermittent failures and refactor code that makes routine changes risky.

For version upgrades or instrument replacement, specialists review driver compatibility and build dependencies before modifying the application. They can reproduce known test cases and compare measurement results after changes. Ongoing support can include executable packaging and technical documentation, so subsequent engineers can understand the test logic and investigate failures.
