FR DSO-TC3 3-in-1 Handheld Oscilloscope 500KHz – Transistor Tester & Signal Generator for DIY Electronics

Overview 

The DSO-TC3 is an upgraded version of the famous TC2, packing three essential tools into a palm-sized device. It functions as a Digital Oscilloscope, a Component Transistor Tester, and a DDS Signal Generator. Its standout feature is the intelligent “Auto Test” mode—simply plug in a component (like a transistor, diode, or resistor), and the TC3 will automatically identify the part, its pinout, and its technical parameters.

Key Features 

• Intelligent Component Tester: Automatically detects NPN/PNP transistors, MOSFETs, IGBTs, JFETs, diodes, capacitors, resistors, and inductors.

• 500KHz Oscilloscope: Perfect for debugging Arduino PWM signals, audio circuits, and low-frequency serial communications.

• Built-in Signal Generator: Outputs 6 different waveforms (Sine, Square, Pulse, Triangle, Ramp, and DC) to troubleshoot your prototypes.

• Portable & Rechargeable: Built-in 1500mAh lithium battery with USB-C charging for hours of bench work.

• Large Color Display: 2.4-inch HD color screen with high-contrast UI for clear data visualization.
