FNIRSI DSO-TC3 3-in-1 Digital Oscilloscope – Transistor Tester & Signal Generator

Compact handheld oscilloscope with component tester and DDS signal generator

The FNIRSI DSO-TC3 is a multifunctional measuring device that combines a digital oscilloscope (10 MS/s, 500 kHz), transistor and electronic component tester, and a DDS function signal generator. It is designed for field engineers, repair technicians, and electronics enthusiasts who need portable precision and reliability. The built-in 1500 mAh lithium-ion battery provides up to 4 hours of operation on a single charge.

Upgraded from the previous DSO-TC2, the DSO-TC3 delivers improved capacitance ESR detection, wider voltage range, higher sampling accuracy and better signal stability. The bright 2.4-inch TFT color display ensures clear readings even in direct sunlight, while the foldable bracket allows comfortable hands-free operation on any workbench.
