This kit emphasizes the key components of an oscilloscope, enabling students to gain both hands-on skills and a deeper understanding of oscilloscope structure and principles. Upon completion, students not only enhance their practical skills but also acquire a functional tool for future electronics learning. Key Features Comprehensive Educational Focus:Complete documentation including schematics, assembly instructions, usage guidelines, and troubleshooting tips, ensuring a high success rate. Varied Component Types:Suitable for learning to identify components and practicing soldering of both through-hole and surface-mount devices (SMD). Functional Learning Tool:Students can use the finished oscilloscope for measuring waveforms in applications such as audio, video synchronization, low-frequency power supplies, and infrared transmission, increasing learning engagement and effectiveness. Advanced ARM Platform:Powered by an ARM Cortex-M3 processor (STM32F103C8) and includes a 2.4-inch color TFT display, making it suitable as an ARM development board for experimentation. Open Source for Customization:Source code is provided, enabling advanced users to modify the oscilloscope, such as converting it into a millivoltmeter, data logger, or other custom applications. Reliable Circuit and Affordable Price:The kit offers a simple and reliable design, making it accessible for a wide range of users. Specifications Maximum Real-Time Sampling Rate: 1Msps Resolution: 12-bit Sampling Buffer Depth: 1024 bytes Analog Bandwidth: 0 - 200KHz Vertical Sensitivity: 10mV/Div – 5V/Div (1-2-5 increments) Vertical Offset Adjustment: With indicator Input Impedance: 1MΩ Maximum Input Voltage: 50Vpp with 1:1 probe (included) 400Vpp with 10:1 probe (sold separately) Coupling Modes: DC / AC / GND Time Base Range: 10μs/Div – 50s/Div (1-2-5 increments) Trigger Modes: Auto, Normal, and Single-shot for capturing transient waveforms Edge Trigger: Rising and falling edges Adjustable Trigger Level: With indicator Pre-Trigger Observation: View waveform before trigger (negative delay) HOLD Function: Freeze the display at any time Test Signal Generator: Built-in 1Hz / 3.3V square wave Waveform Parameters Display:Shows frequency, period, pulse width, duty cycle, max/min values, average, peak-to-peak, and RMS values. Waveform Save/Recall:Waveforms remain saved even after power-off. Enable/Disable Parameter Display: Place the cursor at the time base position and long-press the OK button. Save Waveform: Press SEL + + keys simultaneously. Recall Saved Waveform: Press SEL + - keys simultaneously. Test Mode:Enter by holding the OK button while pressing RESET. If the LED blinks rapidly, it indicates a short circuit on the microcontroller's PB or PC ports (connected to the LCD). Troubleshoot by checking for short circuits. If the LED blinks every 4 seconds, it suggests an open circuit on the relevant connections. Use a voltmeter to locate the fault, following the instructions in the manual.
