A handheld oscilloscope is a compact and portable electronic device used for measuring, analysing, and visualizing electrical signals. Unlike traditional benchtop oscilloscopes, which are larger and typically stationary, handheld oscilloscopes are designed to be easily carried and used in various locations, including on-site maintenance, fieldwork, and other situations where portability is essential.

Handheld oscilloscopes provide flexibility and convenience for engineers, technicians, educators, and enthusiasts who need to perform signal analysis and troubleshooting in diverse locations. With advancements in technology, modern handheld oscilloscopes offer increasingly sophisticated features, making them an essential tool in the electronics and electrical engineering fields.
