RF signals historically are measured using spectrum analyzers, at least that was before oscilloscopes offered sufficient bandwidth for those measurements. With oscilloscope bandwidths over 100 GHz, RF ...

Sometimes the old tricks are the best. [Kevin] learned an old trick about using a ‘scope to sniff RF noise and pays it forward by sharing it in a recent video. He uses an oscilloscope. But does he ...

Oscilloscopes require probes to work, and probes are not all the same. There's a wide variety with versions designed for specific tasks and applications. This ...

It’s a problem that has dogged electronic engineers since the first electrons were coaxed along a wire: that measuring instruments can themselves disrupt the operation of a circuit. Older multimeters ...

The Siekoh Giken OEFS (Optical Electric Field Sensor) optically-coupled E-field probe is a very unique instrument (Figure 1). The company has developed a technology whereby the amplitude and frequency ...

Probing is critical to making quality oscilloscope measurements, and often the probe is the first link in the oscilloscope measurement chain. If probe performance is not adequate for your application, ...
