Big laugh....

Big laugh, this is not television, radio or any other common electronics.

Using Osciloscope, is a big waste of time and money, you get to use this type of measurement technique.
You get there, just no sense and repair cost.

Thank's

Hi folks

I have said many times,that is not important,which equipment do you use.
The main goal are result.If someone can repair phones with
dance and drum ,i don't care

BTW,few days ago one's phone's repair were possible ONLY with oscilloscope.
So,don't say that they are useless.
LCD,battery change or pour out all board with flux and then burn out all elements- this isn't serious repair job....

ya thats right. but as now a days most of the problem can understand with Software boxs, with there error reading so i think that way is better and fast.

Hello
each tools suitable for relative case problem solving.
Software problem,hardware problem.
type of hardware problem,pwm issues,rf issues,data transferings,connections,component testing,values measuring,..... .
One tool is not for all type of issues.
in many cases a mutimeter in ohm section may solve your proble easy than water drinking and a voltage measuring may solve your problems.
or an oscilloscope in analog values and section testing for its functionality.
a fast storage oscilloscope or DSO for viewing fast values that happen in micro seconds.
a spectrum analyzer for rf and pf fuction testings.
or a local gsm or wcdma signal generator for easy and fast working for service centers.
all are suitable for special type of issues.

dear all....

im so sorry... im not an expert... but how we can say osciloscope is not needed???

if we dont know about how to use... we can find the way about how to learn.....


for what reaseon NOKIA make this pic in their schematic????







in mobile phone we have make measurement about voltage, clock, data.. etc...

if we can use it and can read schematic i believe we can solve many hardware failure... of course with software help.....

i hope we can be more profesional with this tool


im not only talk... i use 2 osciloscope in my workshop...






i hope we can help each other to be a better technician....

@ ichal_spy

Can you pls tell us what is Bandwidth of ur Oscilloscope ( i mean is it more than OR equal to 2Ghz)

i fell with simple Oscilloscope upto 50Mhz , Which is very common also not very expansive, one can use only to read maximum 26Mhx XTAL function or Clock XTAL function.

NOTHING MORE THAN THAT (excluding DC voltage - for which a simple DMM is good )

regards
