When choosing an RF instrument, it’s easy to get lost in some of the many specifications that vendors use to characterize an instrument’s performance. Moreover, in a world where wireless technologies ...
The Belar AMMA-2 is a DSP-based, microprocessor-controlled AM modulation monitor that precisely measures and analyzes positive and negative modulation and carrier level. The AMMA-2 was originally ...
Researchers have developed a new design of vertical-cavity surface-emitting laser (VCSEL) that demonstrates record-fast temporal bandwidth. Researchers at the George Washington University have ...
Reporting the industry's best bandwidth and rise times, the ML2490A series peak-power meters features a 65-MHz bandwidth and, when paired with the company’s MA2411B pulse sensor, achieve a typical ...
LASER COMPONENTS supplies iXblue phase and intensity modulators in the near infrared operating from 760nm to 1150nm with a modulation bandwidth of up to 40GHz. Higher optical input power handling ...
This is the fourth in a series of articles about FM transmission systems. The bandwidth of a commercial FM broadcast signal, depending on whether or not subcarriers are used, is about 260 kHz. This ...
Diverse well describes the myriad digital modulation schemes used in modern voice and data communications. The alphabet soup of terminology extends well beyond the familiar QAM and GMSK fundamentals ...
This application note introduces the concepts of digital modulation used in many communications systems today. Emphasis is placed on explaining the tradeoffs that are made to optimize efficiencies in ...
Electro-optic modulators, which convert signals from the electrical to the optical domain, are at the heart of optical communications, terahertz wireless communications, microwave signal processing, ...
