The term used to describe generating a sensor's performance profile during manufacturing is ______?

• A. Calibration
• B. Characterization
• C. Validation
• D. Testing

Answer: (B)

Characterization is the process of mapping how a sensor actually behaves across its operating range and conditions to build a detailed performance profile. This involves systematically measuring the sensor’s output in response to known inputs, at various temperatures, speeds, and other factors, so you capture properties like sensitivity, linearity, offset, noise, and dynamic response. Having this profile lets engineers understand the sensor’s true behavior, set appropriate tolerances, and plan calibration and quality-control steps.

Calibration, on the other hand, is about adjusting the sensor’s output to align with a known reference so readings are accurate at a certain point or range. Validation is confirming that the finished product meets the required specifications in its intended use. Testing is a broader term for evaluating whether the device functions correctly, often across safety and performance checks.
