Product Description

FNIRSI DSO-TC3 Oscilloscope - 3-in-1 Handheld Oscilloscope & DDS Signal Generator & Transistor Tester

Handheld Oscilloscope

DSO-TC3 oscilloscope has a real-time sampling rate of 10MS/s and a 500kHz bandwidth.

With complete trigger function (Single, Normal, Automatic), it can be used freely for both periodic analog signals and aperiodic digital signals.

Up to ±400V voltage signal can be measured.

Equipped with efficient one-key AUTO, the measured waveform can be displayed without cumbersome adjustment.
