FNIRSI® DSO-TC3 Plus 3-IN-1 Handheld 500KHz 10MS/s Digital Oscilloscopes Signal Generator Transistor Tester
Product Description
The FNIRSI® DSO-TC3 Plus is a multifunctional handheld electronic testing instrument that combines a digital oscilloscope, an electronic component tester, and a DDS function signal generator in one compact device. It also provides additional functions such as continuity testing, voltage measurement, regulated diode testing, temperature and humidity measurement, PWM output, and infrared remote control decoding.
The integrated digital oscilloscope features a 500kHz analog bandwidth and a 10MSa/s real-time sampling rate, allowing users to observe periodic analog signals and non-periodic digital signals. It supports AC/DC coupling, automatic waveform configuration, waveform freezing, and multiple trigger modes.
The component tester identifies and measures a wide range of electronic components, including NPN and PNP transistors, MOSFETs, JFETs, IGBTs, diodes, capacitors, resistors, inductors, SCRs, and TRIACs. It also supports automatic component pin identification and measurement of various component parameters.
The built-in function signal generator supports six waveform types: sine, square, pulse, triangle, ramp, and DC. The detailed specifications list an adjustable frequency range of 1–100kHz for the generated waveforms, with adjustable output levels depending on the selected waveform.
Featuring a 2.4-inch TFT color display, a rechargeable lithium battery, and an integrated foldable stand, the DSO-TC3 Plus offers a versatile portable solution for electronics technicians, engineers, students, and hobbyists.
