βš™οΈ Basic Oscilloscope Settings for Mobile Repair

Time/Div (Horizontal Scale): Adjust to capture signal speed (e.g., fast clock signals need smaller scale).

Volt/Div (Vertical Scale): Adjust according to signal level (1V, 3.3V etc.).

Trigger Setting: Stable waveform ke liye proper trigger set karna.

Probe Setting: Use x10 probe for motherboard testing (better accuracy).

πŸ”§ Practical Uses for Technicians

CPU & eMMC Communication Check

Dead mobile repair me sabse zyada use hota hai.

Agar data lines me waveform nahi β†’ CPU/eMMC issue.

Backlight & Display Lines

LCD/LED signals verify karna.

No display issue easily identify hota hai.

Battery Charging Circuit

Charging IC ke switching waveform observe karna.

Touch & Sensor Issues

Capacitive touch signals check karna.

⚑ Pro Tips

Hamesha ground probe motherboard ke ground par connect karo.

Start with low voltage scale (1V/div) aur gradually increase karo.

Short detection me oscilloscope ko DC Power Supply ke sath use karna bohot effective hai.

Agar beginner ho, to 2-channel oscilloscope enough hai.

Advanced repair shops ke liye 4-channel digital storage oscilloscope (DSO) recommended hai.

βœ… Benefits of Using Oscilloscope

Hidden faults easily detect hote hain.

Saves time in dead mobile & IC level repairs.

Increases repair accuracy & success rate.

Professional service quality improve hoti hai.

Customer trust barhta hai jab aap advanced tools use karte ho.
