    Which oscilloscope is the best ?

    Re: Buy a oscyloscoppe The answer depends on the buget, experience and usage. A 100Mhz analog scope is good for general low cost beginner and general use. A 150Mhz DSO is good for lab, design and repair works but at a premium. A PC scope is not for general use, but the price and performance...
