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

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

The FNIRSI DSO-TC4 combines three essential functions in one compact device: a digital oscilloscope, an electronic component tester, and a signal generator. This integration allows for comprehensive waveform analysis, component recognition, and signal testing, making it highly useful for service and diagnostic applications. An intelligent Anti-Burn feature protects the input circuit from damage caused by incorrect probe connections, ensuring safe operation even for less experienced users.

Measurement Functions and Signal Analysis

The oscilloscope offers a measurement bandwidth of up to 10 MHz and a real-time sampling rate of 48 MSa/s, enabling detailed and accurate waveform display for real-time voltage signal analysis. The built-in signal generator provides 13 predefined waveforms with frequencies ranging from 0 to 50 kHz and amplitudes between 0.1 and 3.0 V, allowing simulation of various circuit operating conditions.

Extensive Component Testing Capabilities

The integrated component tester automatically identifies diodes, transistors (including MOSFETs), resistors, capacitors, and other passive and active components. Equipped with test sockets and intelligent component detection, it facilitates quick diagnostics and parameter identification.

Convenient Operation

A 2.8-inch TFT color display provides clear visualization of data and waveforms. The user interface supports eight languages for easy configuration. The control panel offers quick access to key functions such as auto mode, pause, and mode switching, enhancing user convenience.

Connectivity and Power Supply

The device includes a USB-C port for charging and data transfer. Exporting waveforms to a computer is supported for further analysis and archiving. A built-in 3.7 V, 1500 mAh lithium-ion battery ensures extended operation, while an automatic sleep mode helps conserve battery life between uses.
