How your use of power sensors and spectrum analysers can influence outcomes in RF and microwave power measurements, writes Giovanni D’Amore of Keysight Technologies. The ability to make consistent ...

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 ...

Multiphase buck topology is preferred for processors that are drawing increasing amounts of current at lower voltage. Common design practices limit the open-loop bandwidth of the control system to 10% ...

Amateur radio license exams typically have a question about the bandwidths taken up by various modulation types. The concept behind the question is pretty obvious — as guardians of the spectrum, ...

The output power of an RF or microwave system is a key determinant of its performance. For this reason, signal power is measured at every stage – from design and prototyping to maintenance in the ...

New test solutions are emerging to address the test challenges associated with the forthcoming Wi-Fi 7 standard. Wi-Fi 7 covers the (so far, for Wi-Fi) unused frequency range between 6 GHz and 7.125 ...
