Fnirsi Portable 3-in-1 mini oscilloscope DSO-TC4

Portable mini 3-in-1 oscilloscope FNIRSI DSO-TC4
FNIRSI DSO-TC4 is a device that combines three functions: digital oscilloscope, electronic component tester, and signal generator. By combining waveform analysis with component recognition and signal testing functions, it will prove useful in service applications. In addition, the intelligent Anti-Burn function protects the input circuit from damage when measuring probes are connected incorrectly. This makes the equipment safe to use even for less advanced users.


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 can display waveforms with high detail and accuracy, allowing real-time analysis of voltage signals. With 13 predefined waveforms and frequencies in the range of 0-50 kHz (amplitude 0.1-3.0V), the signal generator allows for the simulation of various circuit operating conditions.


Extensive component testing capabilities
The integrated component tester automatically recognizes diodes, transistors (including MOSFETs), resistors, capacitors, and other passive and active components. With test sockets and intelligent component detection, quick diagnostics and parameter identification are possible.


Convenient operation
A 2.8-inch TFT color screen provides easy-to-read data and graphs. The user interface supports eight languages, making it easy to configure the device. The control panel is designed for quick access to key functions, such as auto mode, pause, and mode change.


Connectivity and power supply
The oscilloscope features a USB-C port for charging and data transfer. The ability to export waveforms to a computer facilitates further analysis and archiving of results. A built-in 1,500 mAh lithium-ion battery ensures long operation of the device, and an automatic sleep mode extends the operating time between charges.



Included
oscilloscope, P1600 probe, crocodile clamp, 3x test hooks, user manual, USB-C charging cable, adapter
