Feature:Specification:This digital oscilloscope has similar bandwidth as DSO138 but contains significant improvements in structure, mechanism and operation. It features high sensibility, light and portable size, 2.4-inch TFT screen and protective case. It can display waveform parameters, such as frequency, period, pulse width, duty ratio, MAX./MIN./AVG./Peak-Peak/virtual values.Features:Adopts ARM Cortex-M3 processor (STM32F103C8), and includes a 2.4-inch color TFT display screenUsed for secondary development on the basis of this kit, for example, it can be changed to millivoltmeter, data loggers.Come with instructions, easy to install and operate.Auto/normal/single trigger modes, easy to capture the moment waveform.Available rising or falling edge trigger.Observable previous waveform before trigger (negative delay).Can freeze waveform display at any time (HOLD function).Waveform parameter digital display, including frequency, period, pulse width, duty ratio, MAX./MIN./AVG./Peak-Peak/virtual values.Waveform storage function: Will not lose the waveform after powering off.Short-circuit and open-circuit detection: Can help the user find out the soldering error.TFT controller recognition function.The SMD has been soldered, more suitable for electronic beginners.Specifications:Type: Finished ProductModel: US/ EU (optional)Number of Channel: 1Analog Bandwidth: 0-200KHzSensitivity Range: 5mV/Div - 20V/DivSensitivity error: < 5%Maximum Input Voltage: 50Vpk (1X probe)Input Impedance: 1M ohms/20pFResolution: 12 bitsRecord Length: 1024 pointsCoupling Modes: DC / AC / GND Maximum Real-time Sampling Rate: 1MSa/sTime Base Range: 10us/Div - 500s/Div Trigger Modes: Auto, Normal, and SingleTrigger Types: Rising/falling edge Trigger Position: Center of BufferDisplay: 2.4" Color TFT LCD with 320*240 ResolutionSupply Voltage: DC 9V(8-10V Acceptable)Current Consumption: ~120mA @ 9VProduct Size: 115 * 75 * 22mm / 4.53 * 2.95 * 0.87inProduct Weight: 92g / 3.24ozPackage Size: 202*110*38mm/7.95*4.33*1.50inPackage Weight: 314g/11.07ozNote:Due to the light and screen difference, the item's color may be slightly different from the pictures.Please allow 1-3cm differences due to manual measurement.Package List:1 * Oscilloscope1 * BNC-clip cable1 * Probe1 * Power adapter1 * Users ManualPackage List:1 * Oscilloscope1 * BNC-clip cable1 * Probe1 * Power adapter1 * Users Manual
