A high-integration, handheld laboratory instrument that combines a digital storage oscilloscope, a sophisticated electronic component tester, and a versatile function signal generator into a single, pocket-sized device. Designed for the modern maker bench, it serves as a first-call diagnostic tool for identifying components and visualising signals without the need for a desk full of expensive, bulky hardware.
Electronics enthusiasts often struggle with the "unknown component" dilemma - unmarked transistors or mystery diodes that make troubleshooting a headache. The DSO-TC3 solves this by providing instant, automated pinout detection and characteristic analysis; meanwhile, its integrated oscilloscope and signal generator allow you to inject a waveform and trace it through your circuit in one seamless workflow, saving valuable bench space and reducing setup time.
Built with a rugged housing and a bright 2.4-inch colour TFT display, this unit is engineered for both portability and precision.
