You begin by bringing test benches online—calibrating multimeters, oscilloscopes, spectrum analyzers, and fixtures to ensure every reading is precise. A set of defined procedures guides your work as you execute functional and reliability tests on products and systems. You capture clean data, compare results against specifications, and quickly flag anomalies. When something doesn’t behave as expected, you dive into troubleshooting, collaborate with engineers, and help shape improvements to designs and procedures. Throughout, you keep the lab safe, organized, and compliant with quality and regulatory standards.
