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 ...

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.

What do a Rogowski coil, a magnetic core, and a hall effect sensor have in common? They are all ways you can make oscilloscope probes that measure current. If you think of a scope as a voltage ...

[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 ...

Just about everyone who has ever operated an oscilloscope has used an oscilloscope probe at one time or another. Some have had good experiences, while other had unfavorable ones— possibly as a result ...

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 ...

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.

Yokogawa has launched a new range of high frequency, high voltage differential oscilloscope probes, combining proven features of its existing probes with new capabilities. The range replaces six ...

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 ...

An oscilloscope is useless without the probes necessary to get signals from a device under test (DUT) to the instrument. And probes themselves are far more complicated than simple, ideal conductors ...
