Review: Un pequeño gigante en el taller. - Un instrumento imprescindible para el taller de electrónica, este pequeñín reúne las capacidades de cuando menos 3 aparatos muy útiles para el aficionado o profesional de la electrónica, su tamaño al ser prácticamente de bolsillo lo convierte en un aliado en el trabajo en campo. Lo único que me parece a mejorar es el tamaño del cable de las puntas ya que solo tienen 20 cms. Y limita mucho el poder medir cómodamente algunos componentes. ## Features - FNIRSI DSO-TC3 ingeniously integrates digital oscilloscope, electronic component tester, function signal generator and other functions into one.Equipped with large-size color dot matrix TFT display.Built-in rechargeable lithium battery. Bring more practical functions to users with a small size, it also has good portability. - DSO-TC3 handheld 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.Equipped with efficient one-key AUTO, the measured waveform can be displayed without cumbersome adjustment. - DSO-TC3 transistor tester can automatically identify and measure various transistors, including NPN and PNP transistors, N-channel and P-channel field effect transistors, junction field effect transistors, diodes, dual diodes, thyristors, and resistors, inductors, capacitors and other passive components. Automatic detection of pin definition. Automatically analyze NEC protocol infrared code. - DSO-TC3 transistor tester is especially suitable for fast pairing of transistors, identification of mixed surface mount and wordless components, and preliminary screening of small batch components."Mos Test" mode can test various types of transistors, and can identify device type, pin polarity, hFE, turn-on voltage, junction capacitance, can test capacitance, resistance, inductance components, etc. - Other functional modes: Including circuit continuity test, 0~40V input voltage measurement, PWM output, 0~32V regulated diode measurement, DS18B20 temperature sensor measurement, DHT11 temperature and humidity sensor measurement. Six waveforms: sine, square, pulse stroke, triangle, ramp and DC. ## Technical Specifications | Specification | Value | |---------------|-------| | Item Weight | 449 g | | Package Dimensions | 19.99 x 14.71 x 10.59 cm; 449 g | | Batteries | 1 Lithium Polymer batteries required.
