When using oscilloscopes, we tend to focus so much on the instrument and its features, we tend to forget that choosing the right probe and using it properly can be just as important. It all starts ...

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 ...

One of the most basic tools for tinkering with electronics is a multimeter. Today, even a cheap meter has capabilities that would have been either very expensive or unobtainable back in the 1970s.

There’s a simple reason why high-tech gadgets like PCs, TVs and smartphones are so cheap: they’re mass-produced. By spreading out huge engineering costs over equally huge production volumes, the cost ...

Scientists in Germany have improved a fabrication process for atomic force microscopy (AFM) probe tips. Atomic Force Microscopy is able to scan surfaces so that even tiniest nano structures become ...

More than 30 years after achieving atomic resolution with scanning probe microscopes, scientists remain endlessly fascinated with the ability to “see” and study individual atoms and molecules. For ...
