TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• An Introduction To Direction Finding Methodologies

  All direction finding methodologies are meant to determine the physical or geographical location of a source of radio frequency energy. The choice of an appropriate direction finding methodology to use for a given application is largely a function of the target signal's characteristics, such as frequency and modulation, but is also influenced by the propagation environment as well as cost and complexity.  Recent advances in the development of hybrid direction finding methodologies attempt to overcome some of these restrictions and increase accuracy by using a combination of methodologies.

• AC-DC Converter Testing Fundamentals

  AC-DC conversion stage in front of any electronic equipment is needed. For this purpose, different solutions exist to convert the higher AC voltage to a lower and safe DC voltage.

• Radiated Wireless Coexistence Testing

  This application notegives the reader a clear idea of how to configure standardized test instruments from R&S in order to generate the wanted signal as well as unintended interference signals and conduct measurement to monitor device performance.

• Certium VCS Test System For Aircraft Manufacturers

  New aircraft need to have their radiocommunication systems tested with compact voice communication systems like CERTIUM VCS. This is cost-effective, space-saving, and scalable thanks to its IP-based infrastructure.

• Noise Figure: What Is It And Why Does It Matter?

  Noise figure is a key parameter that quantifies receiver performance by measuring how low a power a signal receiver can detect. This white paper covers the basic principles of noise figure, how to make sense of its specifications, how it is measured, and why this parameter is important in high-performance applications.
