Instrumentation is the set of devices, systems, and techniques used to measure, acquire, control, and record physical or electrical variables of a system. In the context of AJOLLY Testing, instrumentation is the central pillar to ensure precise, reliable, and traceable tests in industrial, laboratory, and research & development (R&D) environments.
It allows executing from functional tests on electronic devices to validations on prototypes, quality control in production, and technical characterizations in the laboratory.
Role of Instrumentation in Testing and Validation
Instrumentation is responsible for:
- Generating controlled stimuli for the devices under test (DUT)
- Acquiring response signals and physical or electrical measurements
- Comparing results with limits and technical specifications
- Recording data for traceability, diagnosis, and statistical analysis
It is indispensable both in manual laboratory benches and in automated test systems for production.

How AJOLLY Testing Applies Instrumentation
AJOLLY Testing integrates instrumentation comprehensively and intelligently into its testing and validation projects:
- Technical selection of instruments suitable for the application (accuracy, range, response time, automation)
- Electrical and mechanical integration with benches, jigs, and test devices
- Complete automation via custom software (LabVIEW, TestStand, C#), with test logic, logs, dashboards, and MES integration
- Management of calibration, traceability, and acceptance limits
- Diagnosis and failure analysis based on captured data
- Statistical analysis of production and R&D with indicators like FPY, CPK, variation by station or operator
