Comparison Table
NI LabVIEW
enterpriseGraphical test software used to automate power supply validation, control instruments, and log measurements.
LabVIEW sequencing plus NI-DAQ timing enables synchronized DAQ logging with oscilloscope waveform capture.
NI LabVIEW is a visual test programming environment used in power supply test systems for building instrument control, sequencing, and measurement capture in one workflow. It pairs with NI hardware to streamline DAQ data acquisition logging and synchronize waveform capture with NI oscilloscopes and other SCPI instruments.
The same block-diagram models also drive automated test sequence scripting for rail behavior checks like ripple and noise and transient response analysis. For integration-heavy labs, LabVIEW projects can standardize hardware control via instrument drivers and reusable libraries built around NI-DAQ and VISA.
- +Block-diagram sequencing links instrument control to capture and logging
- +Tight NI hardware integration improves timing for DAQ and scope workflows
- +Reusable libraries support consistent compliance-style report generation
- +VISA-based control covers common power and measurement instruments
- –Large test systems need disciplined module boundaries to avoid maintenance drift
- –Digital power management bus polling depends on suitable drivers and hardware
- –High-throughput multi-site runs require careful measurement scheduling
- –Complex inrush profiling and protections often need custom test code

Best for: Fits when teams need visual automation for lab power testing with NI DAQ and instrument control.
B&K Precision
SMBPC control software for programmable power supplies and DC electronic loads.
Instrument-driven automated sequencing that ties each measured value to the exact configured step and limit set.
B&K Precision supports end-to-end automated test execution by orchestrating AC source control, electronic load operations, and measurement capture across connected instruments. Results are recorded with run context so engineers can trace pass or fail to specific setpoints and measurement limits. Instrument control typically uses standard connection paths such as GPIB, USB, or LAN, which matches typical laboratory equipment setups. For reporting, the output is structured around test steps so engineering teams can review failures at the step level rather than only at the full-device level.
A key tradeoff is that deep capability depends on instrument pairing and driver support for the specific bench configuration. Teams with a mixed-vendor instrument stack may spend more time mapping channels, scaling factors, and control modes to match the software workflow. B&K Precision fits best when a lab already standardizes on B&K instruments or when the test plan closely matches common production style checks like rail bring-up, protection trip testing, and telemetry polling.
- +Strong integration with B&K Precision test instruments for controlled bench automation
- +Step-linked result logging supports fast failure isolation
- +Test sequence automation reduces operator variance during repetitive DUT testing
- +Report output organizes evidence by configured test steps
- –Advanced automation depth can be limited by available instrument drivers
- –Mixed-vendor benches may require more channel mapping and scaling work
- –Complex multi-instrument synchronisation needs careful setup of timing
- –Sequence maintenance can become manual when test plans change frequently

- +Instrument control supports coordinated setpoints and measurement timing.
- +Integrated result logging helps preserve run context for analysis.
- +Supports protection and rail verification workflows in automated runs.

How to Choose the Right Power Supply Testing Software
We see the biggest differences in how tools drive repeatable test automation and organize results after a measurement run. Watch Automation and reporting quality closely, because both change what you can validate and how quickly you can reuse outcomes across batches.
Automation workflow for full test runs
Why it matters
Automation workflow for full test runs matters because power supply testing often repeats the same steps across units and conditions. Better automation reduces operator drift and keeps the same stimulus and capture order.
How to check
Ask for a sample project that runs start-to-finish: connect instruments, run checks, then save results. Look for reusable steps (not manual clicking) and confirm it can resume or rerun a defined section.
Instrument control and driver support
Why it matters
Instrument control and driver support matters because power rail and signal checks only mean something when the tool can command and read your hardware reliably. Weak compatibility forces manual exports and breaks traceability.
How to check
During a demo, connect representative instruments you already own and request a live test. Verify the software lists your interfaces and provides clear status for connection, ranging, and data capture.
Structured data model for measurements
Why it matters
A structured data model for measurements matters because you will compare units, firmware versions, and configurations over time. When results are structured, you can filter, aggregate, and audit without reprocessing raw files.
How to check
Run one test and inspect how results are stored: per unit, per test step, with timestamps and instrument settings. Export a report and confirm the export retains the same fields you see in the UI.
Reporting and export for audit use
Why it matters
Reporting and export for audit use matters when you need to show what was tested and under what conditions. Good exports let you share outcomes with engineering and keep a consistent evidence trail.
How to check
Generate a report from the demo results and check whether it includes run configuration, pass/fail criteria, and raw-summary links. Try exporting to common formats and verify the folder structure stays consistent across runs.
Test configuration and version control
Why it matters
Test configuration and version control matters because small parameter changes can invalidate comparisons. If configurations are tracked, you can repeat prior setups and explain differences between batches.
How to check
Ask how the tool saves test scripts or templates and how you manage changes over time. Create two variants of one test and confirm the software labels them distinctly in results.
Batch throughput and run management
Why it matters
Batch throughput and run management matters because labs often run many units back-to-back and need consistent timing and labeling. The right workflow keeps queues organized and reduces operator overhead.
How to check
In a demo, queue multiple units with different identifiers and observe whether the tool auto-links each unit to its run and outputs. Check whether it supports parallel planning (even if physical testing is sequential).
Red flags
- Reports that only show a pass/fail badge without test conditions
- Manual steps that break repeatability between units
- Instrument connection that works only with one hardware setup
Fit by situation
- If you run many repeated checks across units, prioritize Automation workflow for full test runs.
- If you already own specific lab gear, prioritize Instrument control and driver support.
- If you need to compare results across months and teams, prioritize Structured data model for measurements.
