FNIRSI DSO-TC4 is a compact 3-in-1 device that combines a 10 MHz bandwidth digital oscilloscope, electronic component tester, and signal generator. It offers sampling rates of up to 48 MSa/s, a clear 2.8″ TFT display, Anti-Burn protection, and a built-in 1,500 mAh battery — an ideal tool for diagnosing and servicing electronics.

The portable mini FNIRSI DSO-TC4 oscilloscope provides practical functions for measuring, checking, and performing basic analysis of electronic circuits. The oscilloscope features a 10 MHz analog bandwidth, a 48 MSa/s sampling rate, and selectable AC/DC coupling, allowing you to monitor voltage waveforms in real time. The automatic measurement function displays important values including maximum, minimum, average, RMS, Vpp, frequency, period, and duty cycle.

The integrated tester automatically identifies a range of components, such as diodes, Zener diodes, resistors, capacitors, inductors, and transistors including MOSFETs, JFETs, and IGBTs. The signal generator offers 13 waveform types with a frequency of 0 to 50 kHz, adjustable amplitude of 0.1 to 3.0 V, and a duty cycle of 0 to 100%. The Anti-Burn function helps protect the input circuit when the test probes are connected incorrectly.

The color 2.8″ TFT display makes it easy to view measured data and waveforms. Power is supplied by an integrated lithium-ion battery with a capacity of 1,500 mAh; the USB-C port is used for charging and transferring data to a computer. The package includes:

  • FNIRSI DSO-TC4 oscilloscope,
  • P1600 probe,
  • alligator clip,
  • 3× test hooks,
  • user manual,
  • USB-C charging cable,
  • adapter.
