FNIRSI DSO-TC4 Portable 3-in-1 Mini Oscilloscope
The FNIRSI DSO-TC4 is a portable 3-in-1 instrument combining a digital oscilloscope, electronic component tester and signal generator in a compact handheld design. It is intended for electronics diagnostics, service work and educational use, where multiple measurement functions are required in a single device. The oscilloscope supports a 10 MHz bandwidth with a 48 MSa/s sampling rate, enabling real-time waveform analysis with sufficient detail for general signal inspection. The integrated signal generator provides 13 predefined waveforms with frequency output up to 50 kHz and adjustable amplitude, allowing simulation of circuit behaviour. The component tester automatically identifies and evaluates diodes, transistors, MOSFETs, resistors and capacitors for rapid fault detection. A 2.8-inch TFT display ensures clear visualization of results, while the 1500 mAh rechargeable battery with USB-C charging supports extended portable operation.
The built-in component tester automatically detects and identifies a wide range of electronic components, including diodes, BJTs, MOSFETs, resistors and capacitors, providing fast parameter evaluation and fault diagnosis. An intelligent Anti-Burn protection system safeguards the input circuitry against incorrect probe connections, improving operational safety. The 2.8-inch TFT color display ensures clear visualization of waveforms and measurement data, while a multilingual interface supports ease of use across different users. A 1500 mAh lithium-ion battery provides extended operating time, and USB-C connectivity enables charging and data export for further analysis and documentation.
