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.

Features

Master your circuit diagnostics with a 3-in-1 design that replaces a standalone oscilloscope, component tester, and signal generator, streamlining your workspace.
Identify mystery components instantly using the automated transistor tester mode, which detects NPN/PNP, MOSFETs, diodes, and even ESR in capacitors with zero manual configuration.
Visualise high-speed signals with a 500kHz bandwidth and 10MSa/s sampling rate, providing enough resolution for debugging Arduino, ESP32, and most hobbyist microcontroller projects.
Verify complex logic and timing using the built-in signal generator, allowing you to output sine, square, and pulse waves up to 100kHz to simulate sensors or clock signals.
Expand your testing toolkit with specialised "Toolbox" functions, including infrared NEC protocol decoding, DS18B20 temperature sensing, and DHT11 humidity measurement.
Safely test high-voltage components like Zener diodes (up to 32V) via a dedicated test area, ensuring you can verify regulation circuits.
Enjoy long-term field use thanks to the USB-C rechargeable 1500mAh battery and a compact, lightweight chassis that fits easily into a toolkit.
