A PQ expert can link an abnormal current or voltage waveform to an abnormal condition on a power system just as a handwriting expert matches a signature to a person. Many facilities now have online ...

Bringing the concepts of pulse shaping and frequency combs together allows the generation of waveforms with both controllable ultrafast time structure and long-term coherence. Two-photon absorption ...

The architecture of an AWG (arbitrary waveform generator) looks like that of a DSO (digital storage oscilloscope) in reverse. Waveform memory plays a critical role in both instruments. DSOs capture ...

RedShark Replay: One from the archives. Gone are the days when a light meter and a trained eye was enough; to do better, we need technological measures and test & measurement equipment. Traditionally, ...
