Frequently Asked Questions

What is the difference between Factory Verified and OEM Compliant Calibration?

The key distinction between Tektronix Factory Verified Calibration and Tektronix OEM Compliant Calibration lies in the additional benefits offered by Factory Verified Calibration. While both services meticulously cover all published/recommended calibration points and strictly adhere to Tektronix and Keithley's recommended procedures, Factory Verified Calibration goes a step further. It includes instrument adjustments for enhanced accuracy, a comprehensive check of instrument specifications across its entire operational range, ensures instruments are up-to-date with firmware and software updates, and includes an exhaustive cleaning process. These added elements in Factory Verified Calibration not only certify precision but also optimize instrument performance and reliability, making it an ideal choice for those seeking a more comprehensive calibration solution.

Can I get Factory Verified calibration at my local lab?

This service is designed to assist lab managers and maintenance coordinators dealing with bulky or permanently mounted equipment, offering the advantage of minimizing critical engineering and production downtime with a one workday turnaround time. Highly trained customer service engineers collaborate with your team to plan, manage, and execute a comprehensive calibration program, ensuring minimal disruption to demanding engineering and production schedules. This service covers calibration for your full fleet of Tektronix or Keithley equipment, and it's backed by ISO 9001 certification and accreditation to ISO/IEC 17025 standards by A2LA, guaranteeing precision and quality.

What calibration service levels are available?

There are different calibration service levels available depending on your requirements. Standard and accredited calibration services provide the traceability needed for regulatory requirements.

Accredited calibrations provide a certificate of calibration with the accrediting body's logo on the document. The calibration date is on the certificate and the calibration due date is only placed on the document when specified by the customer or contractually agreed. A traceability statement is provided. Measurement data and uncertainty for each parameter tested during the calibration is provided.

Some of our equipment is difficult to move. How do we get it calibrated?

Sometimes sending in an instrument to get calibrated isn't an option. From onsite service to local service centers, there are different delivery options available to meet your needs.

Local service centers – Local service centers offer free pick-up and delivery within the locality of the center, and a broad scope of accreditation which helps minimize third-party costs.Tektronix has 27 North American and 18 International locations. Find a service center nearest you.

Periodic onsite service – With this option, customers can plan ahead and avoid having to take equipment out of service to minimize impact on your design and production schedules. This is also the best option to calibrate sensitive or large equipment that can’t be moved.

“Virtual onsite service” – With the concerns surrounding the ongoing COVID-19 pandemic, we’ve also introduced a new “virtual onsite” service where we dedicate the resources and standards that would have been used for onsite service but perform the service in our service center. Virtual onsites, combined with pickup and delivery service, allow for appropriate social distancing where required and offers the same fast turnaround times you would experience with a normal onsite service event.
