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.
