This white paper describes the basic functionality of antennas. Starting with Hertz's Antenna model followed by a short introduction to the fundamentals of wave propagation, the important general characteristics of an antenna and its associated parameters are explained.
This white paper offers the reader a basic understanding of electromagnetic interference (EMI) and compatibility (EMC), various compliance standards and specifications, types of testing available for quantifying equipment performance, and basic approaches utilized to help meet application requirements.
A programmable or step attenuator is externally controlled with maximum attenuation ranges from 0 dB to 127 dB, in steps as small as 0.1 dB. This app note discusses key components in a programmable attenuator system, as well as the best choices for general applications.
Power inductors typically are used for energy storage in DC/DC converters or high-noise filter applications, including motor speed control, adjustable lighting, DC power conditioning, and more. This article delivers the basic information for understanding power inductors, their uses, and benefits.
This application note provides an introduction to the practical uses of RTSAs to reveal important information about the performance of RF/microwave components, track down sources of interference, and monitor the spectrum for activity and security threats.
Parameters that must be considered for RF inductor selection include mounting type, inductance value, current rating, DC resistance, self-resonant frequency, Q factor, and temperature rating. One must balance the desired smaller sizes of the inductor package, and the inductance value and current rating.
Cable assemblies are critical to obtaining correct test results and signal integrity in many applications. Proper care and handling of cable assemblies and connector interfaces is critical for insuring accurate operation.
This article by A.H. Systems presents a step-by-step process of measuring the ambient field strength values for a radiated emissions measurement.
Ferrite isolators and circulators are passive, ferrite devices that act as traffic conductors for RF energy in a system. This app note discusses the basics of ferrite isolators and circulators and describes the three most important specifications for selecting the proper device for your application.
Choosing a new oscilloscope can be daunting — there are hundreds of different models to choose from with widely varying costs and specifications. This article guides you through the maze of considerations and will hopefully help you avoid making what could prove to be an expensive mistake.
