Product Description
The FNIRSI® DSO-TC4 is a multifunctional handheld electronic testing instrument that combines three essential tools in one compact device: a digital oscilloscope, an electronic component tester, and a DDS signal generator. Designed for electronics repair, maintenance, and research and development, it provides a versatile solution for testing circuits and identifying electronic components.
The integrated digital oscilloscope features a 10MHz analog bandwidth and a 48MSa/s real-time sampling rate, allowing users to observe and analyze electronic signals. It supports AC/DC coupling, multiple trigger modes, automatic waveform measurements, and screenshot saving for convenient signal analysis.
The component tester can identify and measure a wide range of electronic components, including transistors, diodes, Zener diodes, field-effect transistors, capacitors, resistors, and inductors. It automatically identifies component types and pin configurations, helping simplify component testing and troubleshooting.
The built-in DDS signal generator supports 13 waveform outputs, with an adjustable frequency range of 0–50kHz and an output amplitude of 0.1–3.0V. Frequency, amplitude, and duty cycle can be adjusted according to the selected waveform.
Featuring a 2.8-inch adjustable-brightness TFT color display, a built-in 1500mAh rechargeable battery, and a lightweight handheld design, the DSO-TC4 is suitable for electronics technicians, engineers, students, and hobbyists.
