FNIRSI DSO-TC4 Portable 3-in-1 Mini Oscilloscope

The FNIRSI DSO-TC4 is a device that combines three functions: a digital oscilloscope, an electronic component tester, and a signal generator. By combining waveform analysis with component recognition and signal testing, it is ideal for service applications. Furthermore, an intelligent anti-burn function protects the input circuit from damage if the measurement probes are incorrectly connected. This makes the device safe to use, even for less advanced users.

A mini oscilloscope lies on the worktop.

Measurement functions and signal analysis

The device offers a measurement bandwidth of up to 10 MHz and a sampling rate of 48 MSa/s. It displays waveforms with high detail and accuracy, allowing you to analyze voltage signals in real time. With 13 predefined waveforms and frequencies ranging from 0–50 kHz (amplitude 0.1–3.0V), the signal generator allows you to simulate various operating conditions.

Extensive component testing capabilities

The integrated component tester automatically recognizes diodes, transistors (including MOSFETs), resistors, capacitors, and other passive and active components. Test sockets and intelligent component detection enable quick diagnostics and parameter identification.

Convenient operation

The 2.8-inch color TFT screen provides clear data and graphs. The user interface supports eight languages, making device configuration easy. The control panel is designed for quick access to key functions, such as automatic mode, pause, and mode change.

Connectivity and Power

The oscilloscope is equipped with a USB-C port for charging and data transfer. Exporting waveforms to a computer facilitates further analysis and results archiving. A built-in 1500 mAh lithium-ion battery ensures long operation, while automatic sleep mode extends the operating time between charges.
