Portable 3-in-1 mini oscilloscope FNIRSI DSO-TC4
The FNIRSI DSO-TC4 is a device that combines three functions: a digital oscilloscope, an electronic component tester and a signal generator. By combining waveform analysis with component recognition and signal testing, it will prove itself in service applications. In addition, the intelligent Anti-Burn function protects the input circuitry from damage when measuring probes are incorrectly connected. This makes the equipment safe to use even for less advanced users.
Measuring functions and signal analysis
The instrument offers a measurement bandwidth of up to 10 MHz and a sampling rate of 48 MSa/s. It allows waveforms to be displayed with a high degree of detail and accuracy, making it possible to analyse voltage signals in real time. With 13 predefined waveforms and frequencies in the range 0-50 kHz (amplitude 0.1-3.0V), the signal generator allows the simulation of various circuit operating conditions.
Extensive component testing capabilities
The integrated component tester automatically recognises diodes, transistors (including MOSFETs), resistors, capacitors and other passive and active components. Thanks to test sockets and intelligent component detection, quick diagnostics and parameter identification are possible.
Convenient operation
The 2.8" TFT colour screen provides easy-to-read data and graphs. The user interface supports eight languages, making it easy to configure the instrument. The control panel has been designed for quick access to the most important 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, and an auto-sleep mode extends operation time between charges.
