oscilloscope can only find faults in signal frequency....and it also depends on how high the capacity of your oscilloscope can read those frequency... in some cases it could also help for no power, for example; measuring the flow of frequency in crystal clock....... | |

Member: 7653 Status: Offline Thanks Meter: 823 | man, do you guys ever use an 'scope? scope will be useful for checking clock signals and other control line on board. these frequency max 26MHz. you wanna measure RF with an 'scope? hehehe need 1900MHz scope for gsm only. UMTS much faster, for this, dont use a scope!! |

Member: 162029 Status: Offline Thanks Meter: 202 | Yes oscilloscope is one of the necessary tools in any electronic repair. If you know the correct frequency reading on a certain circuit in board, you can use it as fault finder. or better if you have a working board then you can compare. |

Oscilloscope is for non radio factors same as oscillators wave form and pwm signals and clocks or datas or for high speed or small lenght and low time values mesurment. oscilloscopes are available in large range of frequncies but its high frequncies is not same as spectrum analyzer for rf measurment. |
