FNIRSI DSO-TC4 Digital Oscilloscope

FNIRSI DSO-TC4 highlights

3-in-1 Multifunctional Device

The FNIRSI DSO-TC4 combines an oscilloscope, signal generator, and transistor tester in one compact tool, making it perfect for electronics maintenance, repair, and R&D projects.

High-Performance Oscilloscope

With a 10MHz analog bandwidth, 48MSa/s sampling rate, and ±400V voltage protection, this oscilloscope delivers precise waveform analysis. It also supports screenshot saving for easy data review and analysis.

Versatile Signal Generator

Generate 13 types of waveforms with a frequency range of 0-50KHz and adjustable output voltage (0-3V). Customize output parameters like frequency, amplitude, and duty cycle to meet diverse testing needs.

Efficient Transistor Tester

Automatically identifies transistor types and pin arrangements, supporting components like diodes, triodes, and FETs. Simplify testing and improve efficiency with accurate performance analysis.

Portable & User-Friendly

Featuring a 2.8-inch TFT color screen, a built-in 1500mAh rechargeable battery (4-hour standby), and a lightweight design, the DSO-TC4 is ideal for on-the-go use in workshops, labs, or field environments.
