Oscilloscope and scope meter calibration involves verifying and adjusting the accuracy of these instruments, which are used to measure and visualize electrical signals in time and voltage domains. The calibration process typically includes checking amplitude accuracy, timebase linearity, frequency response, trigger functionality, and probe compensation against certified reference standards. Any deviations are recorded and adjustments are made to ensure precise signal measurement and display. Regular calibration ensures reliable and repeatable readings, supports troubleshooting and testing in electronics and electrical systems, maintains compliance with industry and regulatory standards, and provides traceable documentation for quality assurance and equipment maintenance.
