FR DSO-TC3 Handheld Digital Oscilloscope & Transistor Tester – 3-in-1 Signal Generator for Electronics Repair

Overview 

Stop cluttering your desk with bulky equipment. The FR DSO-TC3 is a revolutionary handheld device that manages your most critical lab tasks. Whether you need to visualize a PWM signal from an Arduino, test if a salvaged MOSFET is still working, or generate a sine wave to test an amplifier, this device does it all. It features a brilliant 2.4-inch color TFT screen and a built-in lithium rechargeable battery, making it the perfect field tool for on-site repairs.

Three Tools in One Box

1. Digital Oscilloscope: 10MS/s sampling rate and 500kHz bandwidth. Perfect for debugging I2C, UART, PWM, and low-frequency analog signals.

2. Component Tester: Automatically identifies and measures Transistors (NPN/PNP), MOSFETs, Diodes, Resistors, Inductors, and Capacitors. It even detects Infrared (IR) remote codes!

3. Signal Generator: Output Sine, Square, Pulse, Triangle, and Ramp waves to test your circuits’ response.
