An operator interface lets production floor workers run tests without writing code. Learn what it includes, how it compares across frameworks, and how to.

Control a Rigol DP800 series power supply from Python using PyVISA, with multi-channel control, OVP/OCP protection, and TofuPilot integration via OpenHTF.

A complete reference for OpenHTF measurement types, validators, and units, with code examples for numeric ranges, exact matches, percentages, and marginal.

Learn how to use production test data trends in TofuPilot to predict equipment failures and schedule maintenance before downtime occurs.

Learn how to monitor test station health, track uptime metrics, and detect performance degradation using TofuPilot analytics.

Test observability gives full visibility into what your test systems are doing, why they fail, and how they perform. Learn how it applies to manufacturing test.

Design validation testing (DVT) confirms a product meets its design requirements. Learn how to structure DVT in Python and track results with TofuPilot.

Replace your custom PostgreSQL, SQLite, or Access test database with structured test data collection using OpenHTF and TofuPilot.

Learn how to assemble PPAP test documentation from production test data using TofuPilot, including control plans, MSA, and process capability reports.

Learn how to structure OpenHTF tests so repair loops, rework actions, and retests all link to the same serial number in TofuPilot.

PCB design for testability (DFT) guidelines covering test point placement, JTAG boundary scan, programming headers, and how DFT enables automated testing.

Learn how to attach video recordings, log files, and supplementary data to hardware test runs in TofuPilot for synchronized review.
