Instrumentation in electronics is used for precise measurement and analysis of electrical signals, components, and circuit behaviour. Tools like oscilloscopes, multimeters, function generators, and logic analysers help design, test, and troubleshoot electronic systems. These instruments must offer high accuracy, sensitivity, and resolution, with capabilities for capturing fast signal changes and detailed data. User-friendly interfaces, compact design, and digital connectivity are important for efficient workflow in labs, manufacturing, and R&D environments.
