HI JESTINE
it is really good article totally but this part is most important part of it.
Remember also that, if your input signal is not a pure sine wave, it will contain higher frequency harmonics. For example, a 20 MHz pure square wave viewed on a 20 MHz bandwidth scope will be displayed as an attenuated and distorted waveform. As a rule of thumb, try to purchase a scope with a bandwidth five times higher than the maximum frequency signal you wish to measure. Unfortunately, high bandwidth scopes are expensive, so you may have to compromise here.
and must be observed

by the way is 100 Mhz band width scop is suitable for our job? regardless of other factors.

Hi beh,
Yes for normal repair just to see common waveform a 100mHZ analog scope is good enough.

Hi Beh,
If I remember right, some Plasma TV IC's clock around 500 MHz.

Hi Beh,
Yes you can buy that too if you have the budget.
