This kit uses ARM Cortex-M3 processor (STM32F103C8), and includes a 2.4-inch color TFT display screen, can be used as ARM test development board.Can be secondary development on the basis of this kit, for example, it can be changed to Millivoltmeter,With automatic, regular and one-shot modes, easy to capture the moment waveform.Comes 1Hz /3.3V square wave source.With waveform parameter digital display, including frequency, period, pulse width, duty ratio, MAX./MIN././-Maximum real-time sampling rate: 1MspsAccuracy: 12BitSample buffer depth: 1024 bytesAnalog Bandwidth: 0 - 200KHzVertical Sensitivity: 10mV/Div - 5V/Div (in 1-2-5 increments)Adjustable vertical displacement with indicationInput impedance: 1MMaximum input voltage: 50Vpp (1:1 probe), 400Vpp (10:1 probe)Coupling methods include DC/AC/GNDHorizontal time base range: 10s/Div - 50s/Div (in 1-2-5 increments)With automatic, conventional and single trigger modes, it is convenient to capture instantaneous waveformsTrigger with rising or falling edgeAdjustable trigger level position with indicationWaveform before trigger can be observed (negative delay)Waveform display can be freeze at any time (HOLD function)Comes with 1KHz /3.3V square wave sourceDigital display with waveform parameters, the parameters that can be displayed are: frequency, period, pulse width, duty cycle, maximum value, minimum value, average value, -to- value, Save/recall the waveform, the waveform does not disappear when offColour:RedMaterial:ABSSize:18 x 12.5 x 3cmPackage Contents:1 * DIY Digital Oscilloscope Kit1 * ProbeOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
