Metrology and Your Calibration Choices

National and international standards define calibration processes, certification guidelines, and traceability requirements. Tektronix metrologists have supervised the development of calibration levels to meet your needs:

Accredited Calibration, the most comprehensive level of service, meets ISO 17025 requirements. Accredited calibration supports statistical process control methods. Some industries and end-users mandate fully accredited calibration as a contractual requirement.

• Performed by competent technicians, proven capable of performing the required calibration tasks, working in an accredited facility
• Includes, where applicable, adjustments as necessary to restore performance to factory specifications
• Includes a Test Data Report, with measurement uncertainties
• Includes a compliant Certificate of Calibration

Traceable Calibration brings the instrument within factory specifications and is sufficient for many applications. The calibration includes customer notification in the event of a measurement issue, as well as:

• Verification of specifications
• Traceability to National Metrology Institutes
• Certificate of Calibration
• Statement of received conditions (in or out of tolerance)
• Adjustments to restore performance to factory specifications
• Test data report (optional)

A third tier is Functional Verification. Functional verification is a level of calibration and is designed to cover non-measurement instruments that neither acquire nor source signals to be measured. A functional verification includes:

• Preventative maintenance
• Firmware updates
• Confimation that the instrument's measurement accuracy meets catalog specifications (if any)
• Intended for instruments that don't meet requirements of Traceable Cal
• Adjustment as necessary to restore performance to factory specifications
• A Statement of Compliance (i.e. received conditions in or out of tolerance)

Metrology Facts

• Metrology processes and standards are not static. NCSLI, A2LA, DKD, and other metrology bodies meet regularly to plan for changing technology requirements.
• Tektronix plays an active role in industry metrology committees including NCSLI, A2LA, and DKD
• Tektronix metrologists validate and verify test methods for emerging products, then bring these proven methods into the Service program for standardized calibration support
