Adopts ARM -M3 processor (STM32F103C8).Used for secondary development on the basis of this kit, for example, it can be changed to millivoltmeter, data loggers.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././-/virtual values.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././-/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.The SMD has been soldered, more suitable for electronic beginners.Number of Channel:1Analog Bandwidth:0-200KHzSensitivity Range:5mV/-20V/Sensitivity error:Less than 5%Maximum Input Voltage:50Vpk (1X probe)Input Impedance:1M ohms/20pFResolution:12 bitsRecord Length:1024 pointsCoupling Modes:DC/AC/GNDMaximum Real-time Sampling Rate: 1MSa/sTime Base Range:10us/-500s/Trigger Modes:Auto, Normal, and SingleTrigger Types:Rising/falling edgeTrigger Position: Center of BufferDisplay:2.4inch Color TFT LCD with 320x240 ResolutionSupply Voltage:DC 9V(8-10V Acceptable)Current Consumption:120mA @ 9VDifferent batches, the product may have color difference, does not affect the use ofPlug Type:EU Plug,it applies to Indonesia, Germany, France, , Italy and so on.Voltage:AC 220VColour:WhiteMaterial:PlasticPackage Contents:1 * Oscilloscope1 * BNC-clip cable1 * Probe1 * Power adapterOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
