A calibration label does not always mean your instruments are in tolerance and making accurate measurements. If your instrument is out-of-specification (out-of-tolerance), you can no longer trust your test results.

Are you 100% confident your calibration service partner provides an accurate calibration?

You May Face More Risk Than You Know

When was the last time you verified the information on your calibration report? Using older instruments to calibrate your test equipment puts you at risk for lower accuracy. Or even worse, critical parameters may not be tested at all.

Data from 10 calibration service providers show all but one tested performance of less than 50% of the instrument’s specifications — in some cases, testing was less than 25%. If your tests rely on key critical specifications that are missed during calibration, your test equipment is likely out-of-specification. And you can no longer trust your test results. This measurement uncertainty puts your reputation at enormous risk.

There are risks in not checking calibration certificates.

Avoid Measurement Decision Risk

Calibration standards ensure that your test system is performing to specification. When you perform a measurement and subsequently compare the result to a specification, making a statement of conformity, you have two possible outcomes:

A. correct pass / fail decision

B. incorrect pass / fail decision

Two labs, A and B can observe identical measurement results but with different measurement uncertainties.

Given the choice of A or B, you would want to select A. Choice B often occurs when third-party calibration labs measure your instrument’s current performance with lab standards that are not up to the task.

Keysight minimizes the uncertainties of measurements during the development of performance tests, both in the selection of lab standards and in the calibration procedures. You can count on correct pass / fail results for any calibration that Keysight performs.

Avoid Overdue Calibrations

Select Infiniium Real-Time Oscilloscopes, Network, Signal, and Noise Figure Analyzers now include on-screen calibration due reminders on the front panel.

To ensure your instruments perform to Keysight factory specifications, calibrations are required. Our new feature, PathWave Calibration Advisor, helps you count on the accuracy of your measurements. From your screen, you get calibration due reminders, access to your calibration certificates, list of instrument configuration details, and easy service ordering direct from Keysight.

PathWave Calibration Advisor provide on-screen calibration-due reminders.

Keysight Instrument Calibration

We measure every specification, every option, every time.

Select the right calibration for your Keysight instruments. Maybe you need measurement uncertainties, guardbanding, an accredited calibration, or a primary standards lab calibration. Alternatively, perhaps your calibration report needs to satisfy a particular ISO or ANSI metrology standard such as IS0 17025:2005 or ANSI Z540.3-2006. Keysight offers a wide range of calibrations to ensure you meet your requirements to your local and global needs.

All Keysight Service centers are accredited to their local accreditation body such as JCSS, CNAS, Poverka, UKAS, ANAB, and so many more.

Keysight offers a wide range of instruments. This images shows just a few of those available, and all should be calibrated regularly.
