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 110KHz 03.3V 50%, vertical sensitivity 10mV to 10V , horizontal time base range 1us10s, 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 12 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.Specification:Item Type: Digital OscilloscopeMaterial: ABSMain Parameters Of The Machine Model DSO TC3Display 2.4 Inch TFT Color Screen, LED BacklightPower Supply Voltage1 x 803450 1500mah Li Polymers Battery (Shipping With Built In Battery)Charging SpecificationUSB Type CStand SpecificationsOne Piece Foldable StandDigital Oscilloscope Mode Parameters Realtime Sampling Rate10MSa/sAnalog Bandwidth500KhzInput Impedance1MOCoupling MethodAC or DCTest Voltage Range400VVertical Sensitivity10mV-10VHorizontal Time Base Range1us-10sTrigger ModeAuto, Normal, SingleTrigger TypeRising Edge Or Falling EdgeWaveform FreezeYesAutomatic MeasurementYesComponent Test Mode ParametersClassRangeDescriptionTriode greater than 10 less than 600Magnification hfe, base emitter voltage Ube, lc/le, collector emitter reverse cutoff current lceo, lces, protection diode forward voltage drop UfDiodeForward voltage drop <4.5VForward voltage drop, junction capacitance, reverse leakage currentVoltage regulator diode0.01-4.5V(1 2 3 test area) Forward voltage drop, reverse breakdown voltage0.01-32V(K A A test area) reverse breakdown voltageField Effect TubeJFETGate capacitance Cg, drain current ld at Vgs, protection diode forward voltage drop UfIGBTDrain current ld at Vgs, protection diode forward voltage drop UfMIOSTETTurn on voltage Vt,gate capacitor Cg,drain resistor Rds,protection diode forward voltage drop UfOne way thyristorTurn on voltage <5V,gateGate voltageBi directional thyristorTrigger current <6mACapacitance25pF-100mFCapacitance value, loss factor VlossResistor0.010-50MOResistance ValueInductance10uH-1000uHInductance Value, DC ResistanceBattery0. 1-4.5VVoltage value, positive and negative polarityInput Voltage0-40VVoltage ValueDS 18B200-85CTemperatureDHT10-60C/5-95%HumidityInfrared remote control decodingprotocol infrared codingDisplay user coding and data coding, well display the corresponding infrared waveformSignal generator parameters Sine Waving 1-10KHz/0-3.3V/50%Rectangle Waving1-100KHz/3.3V/50%Pulse Waving1-100KHz/3.3V/0-100percentTriangular Waving1-10KHz/0-3.3V/50%Slope1-10KHz/0-3.3V/0-100percentDC0-3.3V.Package List:1 x Oscilloscope1 x USB Cable3 x Test Hook Cable1 x Ordinary Probe1 x Adapter 1 x P6100 High Voltage Probe 1 x Instruction Manual
