Electrified telegraphy was the first practical use of electricity for long-distance communication. This was a tremendous improvement over flashing lights and waving signal flags. The well-known Morse ...

Those of you who work in wireless know the basics, such as the higher the data rate, the wider the bandwidth you are going to use. With spectrum being in such short supply, or perhaps just way too ...

Optical vector analysis has emerged as a critical tool for characterising optical devices, enabling simultaneous measurement of amplitude and phase responses over wide bandwidths. This technique is ...

Receive fundamental information on analog and digital modulation methods by requesting this pocket guide. The guide also provides important signal generator specifications and parameters that should ...

Linearity and power efficiency in power amplifiers are critical to the signal quality and battery life of 5G designs. Traditional methods for characterization testing of power amplifiers (PA), however ...

Modulation bandwidths continue to grow, promising higher data rates yet imposing test difficulties. Most test technologies are still rooted in past, narrowband architectures, which are increasingly ...
