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 ...

Evaluation Engineering has a great article about scope probes from a guy at Agilent. Jae-Yong Chang gives a pretty good overview of the issues surrounding scope probes. I would add two stories of my ...

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 ...

For oscilloscopes, Yokogawa has replaced six existing differential voltage probes with three expanded capability probes, and is offering new current probes too. “Recent trends for higher voltages in ...

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.

[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 ...

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.
