Automated test systems are selected differently from standalone instruments. The right scope depends on the device under test, measurement sequence, throughput target, operator workflow, safety requirements, and how results must be stored or reported.
Quick Recommendation
| Need | Recommended fit | Why it fits |
|---|---|---|
| Production end-of-line test | Turnkey automated test rack | Combines instruments, switching, fixtures, operator workflow, pass/fail limits, and reporting in one commissioned system. |
| RF or PXIe multi-instrument validation | PXIe modular test platform with automation | Scales VNA, VST, converter, AWG, DAQ, and DMM modules inside a common chassis and software environment. |
| EV, inverter, battery, or power electronics test | Power source/load rack | Integrates programmable DC/AC sources, electronic loads, interlocks, measurement, and traceable reporting. |
| Repeatable DUT loading and operator safety | Custom test fixture | Controls contact geometry, shielding, high-voltage access, sensors, barcode workflow, and cycle-life requirements. |
System Scope Checklist
| Decision area | What to define | Why it matters |
|---|---|---|
| DUT and interfaces | Connectors, signal levels, RF ports, power rails, communication buses, mechanical drawings. | Determines fixture design, switching topology, safety boundaries, and instrument selection. |
| Measurements | Required stimulus, limits, resolution, calibration path, uncertainty, and timing. | Prevents under-scoping instruments or overbuilding a rack around unnecessary performance. |
| Throughput | Cycle time, batch size, number of operators, barcode flow, retest rules, and uptime target. | Drives parallel channels, switching speed, fixture ergonomics, and software workflow design. |
| Safety | High voltage, RF exposure, interlocks, emergency stop, guarded access, and operator training. | Safety hardware must be designed with the rack rather than added after the test sequence is complete. |
| Reporting | CSV, PDF, database, dashboards, serial-number traceability, and MES or PLM integration. | Determines the control interface, data model, and acceptance documentation. |
How to Decide
Start with the acceptance test
Define what a passing unit must prove before choosing hardware. A clear acceptance sequence helps size instruments, switch paths, fixtures, software screens, and calibration artifacts.
Separate validation and production needs
Validation benches often need flexibility, debug visibility, and manual override. Production systems need repeatable operator flow, fast load/unload, robust pass/fail limits, and clean report generation. The same instruments can be used, but the system design is different.
Plan factory and site acceptance early
XGY automated systems are normally scoped around factory acceptance testing, on-site commissioning, calibration documentation, and operator training. Defining those acceptance criteria early reduces late-stage rework.
Engineering Acceptance Checkpoint
A quotation-ready automated rack should define at least 1 known-good run, 1 forced-fail run, 1 emergency-stop or interlock test, 1 communication-loss case, and 1 exported report. The report should preserve DUT ID, station ID, recipe, operator, date/time, software version, instrument IDs, calibration status, measured values, limits, and pass/fail result. For 19-inch rack builds, add slot count, power budget, airflow, fixture I/O, and network path. Reject the scope if the test passes only with a supplier engineer present or if operators can bypass fixture, safety, or recipe states.

FAQ
Engineering FAQ
What should be scoped before choosing an automated test system?
Scope the DUT, measurement sequence, fixture, instruments, switching, safety limits, throughput target, operator workflow, data model, calibration needs, and support model.
What makes an automated test system production-ready?
It is production-ready when known-good, known-fail, emergency-stop, communication-loss, fixture-open, and report-export cases are tested and repeatable by a second operator.
What evidence should be included in factory acceptance?
Include the final BOM, wiring diagram, software version, test recipe, limits, instrument serials, calibration state, fixture drawings, safety checks, and exported sample reports.
