How to Choose an XGY Automated Test System

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	Best 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, traceable calibration, and operator training. Defining those acceptance criteria early reduces late-stage rework.
