TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• 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.

• 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.

• Characterizing Parasitic Components In Power Converters

  With the rise of wide-bandgap semiconductors like GaN and SiC, characterizing parasitic components in power converters is crucial for maintaining efficiency and preventing performance issues.

• Field Probe Correction Factors

  To better achieve accurate field level measurements, it is helpful to have an understanding of field probe calibrations, the factors generated, and what’s presented as data during testing. This application note presents how to utilize the factors presented for inclusion into test data, how to generate composite measurements, and why calibrations are performed at selected frequencies.

• S-Parameters For High-frequency Circuit Simulations

  Understanding the meaning of S-parameters, how they are measured, and their limitations can lead to more meaningful RF- and microwave-frequency simulations.
