Features:1. 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.2. Can be secondary development on the basis of this kit, such as it can be changed to Millivoltmeter, data loggers.3. Adjustable vertical displacement, and with instructions.With automatic, regular modes, easy to capture the moments waveform.4. Available rising or falling edge trigger.5. Observable previous trigger waveform (negative delay).6. Can freezing at any time waveform display (HOLD function).7. Comes 1Hz /3.3V square wave test signal source.8. With waveform parameter digital display, including frequency, period, pulse width, duty ratio, MAX./MIN./AVG./virtual values.9. Waveform storage function: will not lose the waveform after power off.10. Short-circuit and open-circuit detection: can help the user find out the soldering error.11. TFT controller recognition function.Notice:1.Actual color may be slightly different from the image due to different monitor and light effect2.Please allow 1-3cm deviation due to manual measurementDescription:Maximum Real-time Sampling Rate: 1MspsAccuracy: 12BitSampling Buffer Depth: 1024 bytesAnalog Bandwidth: 0-200KHzVertical Sensitivity: 10mV / Div - 5V / Div (1-2-5 progressive manner)Input Impedance: 1MMaximum Input Voltage: 50Vpp (1: 1 probe), 400Vpp (10: 1 probe)Coupling Modes: DC / AC / GNDThe Horizontal Time Base Range: 10s / Div - 50s / Div (1-2-5 progressive manner)Supply Voltage: DC 9VPCB Size: 117 * 76mm / 4.6 * 3 inchScreen Size: 52 * 40mm / 2 * 1.57 inchNote: This DIY kit is not soldered yetincludes:1 x DSO138 Digital Oscilloscope or1 x Power Supply (US Plug, EU Plug optional)or1 x P6100 ProbeAbout Shipping: All items will be shipped within 3 business days after the payment is received.
