Brand

Model

Feature:
1. Convenient and 3 in 1: This digital oscilloscope, electronic component tester, and PWM signal generator function, combined into one. The oscilloscope has a realtime sampling rate and a bandwidth of 500 kHz. Voltage signals up to 400V can be measured.
2. Identify Device Type: Oscilloscope mode can test the signal waveform of the circuit, while Mos test mode can test various types of transistors, which can identify device type, pin polarity, hFE, on state voltage, junction capacitance, resistance, inductive components, etc. Signal generator mode, you can use sine, pulse, triangular or ramp waveform.
3. Sine Waveform Frequency Output: The signal generator has 5 built in basic waveforms, sine waveform frequency output 1‑10KHz 0‑3.3V 50%, vertical sensitivity 10mV to 10V , horizontal time base range 1us‑10s, more waveform data can be obtained per unit time, thus making the waveform more accurate.
4. TFT Screen: The oscilloscope is powered by a built in 1500 mA battery, which will be fully charged in 1‑2 hours via a 5V 2A adapter and can operate for 4 hours (green indicator for completion/red indicator for charging). The digital handheld pocket oscilloscope and transistor tester is designed with a high resolution 2.4 inch TFT screen with adjusting backlight. Better reading experience and easy to use.
5. Multi Interface Screen Display: The oscilloscope can test different functions and support multi interface screen display. With keypad design, it is more convenient to operate and select different test function modes.
6. Applicable Items: The oscilloscope supports PC online operation, which is especially suitable for fast pairing of transistors, identification of mixed face mount and wordless components, and initial screening of small batch components. It can automatically identify and measure various transistors, including NPN and PNP transistors, diodes, double diodes, etc.
