Portable Display Frequency Digital Oscilloscope TFT Screen Welded Making Kit

Portable Display Frequency Digital Oscilloscope TFT Screen Welded Making Kit Features: This kit uses ARM Cortex-M3 processor (STM32F103C8), and includes a 2.4-inch color thin film transistor 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, data loggers. Adjustable vertical displacement, and with instructions. With automatic, regular and one-shot modes, easy to capture the moment waveform. Available rising or falling edge trigger. Observable previous trigger waveform (negative delay). Can freeze at any time waveform display (HOLD function). Comes 1Hz /3.3V square wave test signal source. With 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 power off. Short-circuit and open-circuit detection: can help the user find out the soldering error. TFT controller recognition function. Specifications: Supply Voltage: DC 9V Size: 128*88*27mm Maximum Real-time Sampling Rate: 1Msps Accuracy: 12Bit Sampling Buffer Depth: 1024 bytes Analog Bandwidth: 0-200KHz Vertical Sensitivity: 10mV / Div - 5V / Div (1-2-5 progressive manner) Input Impedance: 1MΩ Maximum Input Voltage: 50Vpp (1: 1 probe), 400Vpp (10: 1 probe) Coupling Modes: DC / AC / GND The Horizontal Time Base Range: 10μs / Div - 50s / Div (1-2-5 progressive manner) Package Included: 1 * DSO138 DIY Digital Oscilloscope Kit Note: 1. Due to the light and screen difference, the item's color may be slightly different from the pictures. 2. Please allow 0.5-2 cm differences due to manual measurement.
