| These photos show exactly that. Oscilloscope makes you "look" proffesional, and means you can charge more money to run a repair course.
But really, it is useful?
Personally, I dont think so.
I use oscilloscope in other areas, when designing circuits or creating test procedures.
Also I have repaired many many phones since < 2001.
Guess how many times I used oscilloscope on GSM board? none.
Your phone is dead? -> connnect on flasher and see error messages.
Your phone has no signal? -> do manual network search, is problem Tx or Rx?
Of course, we know the charge ways, signal ways, keypad ways from simply looking at the circuit board and using 10 years built knowledge working with these devices!
This method is fully tested in a repair centre, there is NO REAL NEED for 'scope! |
