Metrology and Calibration
What is Metrology?
Metrology ensures that your calibrated instruments deliver accurate results with provable validity. The mission of metrology is to maintain measurement standards, to develop effective new methods, and to ensure that measurements are accepted uniformly around the world.
Why calibrate? Your instruments need to be calibrated against known standards so their results can be trusted to have a universally accepted meaning. Metrology is the science that supports this trust—in both the "meaning" and the measurements:
- Metrology defines calibration and ensures predictable performance from your measurement tools.
- Metrology is the discipline that defines standards and codifies accreditation and traceability.
- Metrology expertise is at the heart of Tektronix' reputation for accuracy, precision, and performance.
At Tektronix, metrology professionals guide calibration policies and procedures at accredited calibration facilities around the world. When you choose Tektronix as your service provider, you get the benefit of an experienced metrology staff plus seasoned technicians applying deep product-specific knowledge.
The result? Services guaranteed to be of the highest quality in the industry.
What is Calibration?
Calibration is all about confidence in the measurement results you're getting. Calibration assures you that your measurements are accurate within the specification limits that led you to select the instrument in the first place.
Every new Tektronix measurement product arrives freshly calibrated and adjusted, with a Certificate of Traceable Calibration. Dig a little deeper into the documentation and you will find details about recommended calibration intervals. These routine calibrations are your prescription for the continued health and performance of your instrument.
What are the costs and risks of not calibrating?
- False passes or (equally undesirable) false failures in production. False passes can send inferior products to your customers, ruining your reputation for quality. False failures end up in the reject bin, ruining yields and prompting costly rework or discards.
- Inaccurate measurements can distort your findings about the behavior of an emerging design. Imagine going through an unnecessary design turn because your instrument wrongly measured a rise time!
- Is your volt the same as your customer's volt? Is your nanosecond the same as their nanosecond? Commerce depends on globally agreed standards of weights and measures. Only traceable calibration can ensure adherence to these standards.
- There may be contractual requirements stipulating a regular calibration regimen. The penalty for non-compliance could be fines or loss of business.
Today's digital instruments are not exempt from regular calibrations. Even though they inherently are more stable than their analog predecessors, their tolerances are much narrower than in the past. And even the latest digitizing instruments have analog circuitry—preamplifiers, buffers, etc.—whose performance can change over time.
A regular schedule of calibrations will keep your Tektronix instrument in optimal condition to support your design, troubleshooting, and manufacturing work.
