The FNIRSI DSO-TC4 oscilloscope is a portable 3-in-1 device that combines a digital oscilloscope, electronic component tester, and signal generator. The device offers waveform analysis and component identification, proving its usefulness in service applications. The smart Anti-Burn function protects input circuits from damage, making the device safe to use even by less experienced users.

Signal measurement and analysis functions
The device offers a measurement bandwidth of up to 10 MHz and a sampling rate of 48 MSa/s. It is capable of displaying waveforms with high detail and accuracy, allowing real-time analysis of voltage signals. With 13 preset waveforms and frequencies in the range of 0-50 kHz (amplitude 0.1-3.0 V), the signal generator allows simulation of various circuit operating conditions.

Extensive component testing capabilities
The built-in component tester automatically recognizes diodes, transistors (including MOSFETs), resistors, capacitors, and other passive and active components. The device features test sockets and smart component detection for quick diagnosis and parameter identification.

Pleasant operation
The 2.8-inch TFT screen provides clearly readable data and graphics. The user interface supports eight languages, facilitating device setup. The control panel is designed for quick access to key functions such as auto mode, pause, and mode switching.

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