Recently, an EDN reader asked “Why do oscilloscope manufacturers put amplifiers on their probe tips rather than in the oscilloscope?” Placing the amplifier in the probe minimizes signal losses in the ...

[IMSAI Guy] wants you to build a non-contact scope probe. The cost? Assuming you have a bit of wire and a regular scope probe, it won’t cost you anything. Why do you want such a thing? You can see ...

Probing is critical to making quality oscilloscope measurements, and often the probe is the first link in the oscilloscope measurement chain. If probe performance is not adequate for your application, ...

This application note discusses on using a passive probe which is commonly used in an oscilloscope, only in this case, it will be used for a spectrum analyzer. A portion of the preferences and ...

It’s a problem that has dogged electronic engineers since the first electrons were coaxed along a wire: that measuring instruments can themselves disrupt the operation of a circuit. Older multimeters ...
