TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• Voltage Standing Wave Ratio (VSWR) Explained

  Explore the evolution of VSWR from its humble beginnings in telegraph lines to its vital role in modern RF engineering, illuminating its practical applications and underlying principles.

• eUICC Profile Handling

  This application note describes the eUICC compliance and remote eUICC provisioning test solution based on R&S CMW500/CMW290 and COMPRION eUICC Profile Manager software tool with focus on M2M devices.

• 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.

• Making Higher Accuracy Oscilloscope Measurements

  One of the most important functional blocks in a digital oscilloscope is the analog-to-digital converter or ADC. This white paper explains why ADC resolution has become a more important consideration in oscilloscopes, especially for measuring small signal details.

• 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.
