III. Eight Classic Experiment Cases (Directly Aligned with Course Syllabus)
Experiment 1: Arduino Smart Car PID Tuning
Equipment Configuration:
Channel 1: Motor PWM waveform → measure response time
Logic probe: Encoder pulse → calculate actual speed
Protocol decoding: Bluetooth remote control command
Result: Visualize the effect of PID parameters on overshoot
Experiment 2: Solar MPPT Algorithm Verification
Use function generator to simulate light intensity change (output 0-5V)
Channel 1 monitors DC/DC output voltage
Channel 2 monitors battery charging current
Automatic Calculation: Efficiency η = (Vbat×Ibat)/(Vsolar×Isolar)
Experiment 3: Power Consumption Analysis of IoT Devices
Ultra-Low Power Mode Capture:
Set up segmented storage to record 24-hour waveform
Identify peak current during sleep/wake-up
Power Consumption Statistics:
Average current: 1.2 μA
Peak current: 85 mA (Wi-Fi startup)
Section 4 Golden Rules for Safe Operation
1. Electrical Safety Specifications
Prohibited Voltage Range:
Do not measure >300 V mains power (high voltage differential probe required)
Do not use 50 Ω input impedance for high voltage measurement (will burn out the front-end circuit)
Grounding Check:
The test bench must be equipped with a leakage current protector (operating current ≤30 mA)
2. Equipment Protection Measures
Probe Damage Prevention:
Put on the crash-proof protective cap (standard accessory) immediately after use
Storage Management:
Remove the battery for long-term storage (to prevent over-discharge)
3. Data Security Settings
Student Permission Lock:
Lock calibration menu and delete function (prevent misoperation)
Automatic Backup:
Automatically save experimental data when USB is inserted
Step 2: Complete basic measurement via touch screen
Tap 【WaveGen】 → Generate a 1 kHz sine wave
Press 【Auto Scale】 → The oscilloscope automatically displays a stable waveform
Gesture pinch to zoom → Expand to display a single period of the waveform
Tap 【Measure】 → Select "Frequency/Peak-Peak Value"
Step 3: Advanced Protocol Analysis (Take I2C as an Example)
Connect Channel 1 to SCL, and Channel 2 to SDA
Enable 【Decode】 → select I2C protocol
Set trigger condition: Address = 0x50
