Test probes go a long way toward ensuring accurate, repeatable test results. Here's a look at how both active and passive test probes are evolving to match today's broadening oscilloscope bandwidths.

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 ...

At its simplest, a scope probe provides a physical and an electrical connection between a device or circuit under test and an oscilloscope's input amplifier. These days, most engineers and technicians ...

In a pair of columns recently, Probing pointers and Probing Pointers: Take 2, I discussed some of the issues that arise in using scope probes as frequencies increase. Alas, too few engineers do a real ...

This file type includes high resolution graphics and schematics when applicable. Selecting the right probe for your application is the first step toward making reliable oscilloscope measurements.

Tektronix has announced a second-generation of IsoVu isolated oscilloscope probes, claiming smaller size, easier use and enhanced electrical performance. Isolated probes are for probing power systems ...

Micsig Technology is aiming at mains and high-voltage GaN power supply development with a series of optical fibre isolated oscilloscope probes, with bandwidths up to 1GHz and risetimes down to ≤350ps.

[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 ...
