My very first measurement was, of course, the calibration signal built into the scope. As [Chris Meyer] at Sector67 hackerspace here in Madison put it, you want to make sure you can probe a known ...

[Christer Weinigel] needed to get some measurements of a differential clock signal that was ticking ... a high-frequency active differential oscilloscope probe, and they’re not cheap.

SENSEPEEK SQG-series passive high-frequency hands-free oscilloscope probes are designed for both ac and dc GHz applications.

Agilent recently introduced the Infinium 90000, a 33 GHz scope. (I want one of those!) But how do you probe a signal that fast? A 5 pF probe will look like a one ohm load at that speed. That’s over 2 ...

Saelig Company, Inc. has introduced the Sensepeek SQG-series of passive high-frequency hands-free oscilloscope probes, designed for both AC and DC GHz applications.

On the heels of a NASA spacecraft's historic close flyby of the sun on Christmas Eve, scientists on Earth have one question on their minds: Did their probe survive as an epic Christmas gift ...
