Signal Generator
A Signal Generator is a common piece of test equipment used in electronics repair and maintenance. Think of it as a tool that creates electrical patterns needed to test and fix electronic devices. Just like a doctor uses different tools to check your health, repair technicians use signal generators to check if electronic equipment is working correctly. They can create different types of electrical signals to test everything from car radios to medical equipment. When you see this term in a resume, it usually means the person knows how to use this tool for troubleshooting and fixing electronic devices.
