FNIRSI DSO-TC4 3-IN-1 10MHz 48MSa/s Digital Oscilloscope Transistor Tester Signal Generator

FNIRSI DSO-TC4 is a device that combines three functions: digital oscilloscope, electronic component tester and signal generator. By combining waveform analysis, component recognition and signal testing functions, it proves useful in service applications. In addition, the intelligent Anti-Burn function protects the input circuit from damage if the probes are connected incorrectly. This means that the equipment can be used safely even by less experienced users.
The device offers a measurement bandwidth of up to 10 MHz and a sampling rate of 48 MSa/s. The device can display waveforms with great detail and accuracy, enabling real-time analysis of voltage signals. The signal generator with 13 predefined waveforms and frequencies between 0-50 kHz (amplitude 0.1-3.0 V) enables the simulation of different circuit operating conditions.
The integrated component tester automatically detects diodes, transistors (including MOSFETs), resistors, capacitors and other passive and active components. Quick diagnostics and parameter identification are possible with test sockets and intelligent component recognition.
The 2.8-inch TFT color screen provides easy-to-read data and graphs. The user interface supports eight languages, which makes it easy to configure the device. The control panel is designed to provide quick access to the most important functions, such as automatic mode, pause and mode switching.
The oscilloscope has a USB-C port for charging and data transfer. The ability to export waveforms to a computer facilitates further analysis and archiving of results. The built-in 1500 mAh lithium-ion battery ensures a long operating time of the device, and the automatic sleep mode extends the operating time between two charges.
