TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• VSWR Conversion To Reflected Power

  VSWR measures how efficiently RF power is transmitted through a load, with high VSWR indicating poor efficiency. Explore VSWR's relation to return loss, reflection coefficient, and mismatch loss.

• 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.

• Measurement Of The Phase Between Several Signals

  Measurement of magnitude can be done with spectrum analyzers, power meters etc. For a phase measurement, a VNA is the easiest, fastest and most accurate instrument. 

• 5G New Radio Over-The-Air Base Station Receiver Tests

  This application note describes all mandatory RF receiver tests, according to the Release 16 (V16.3.0). It also offers a brief introduction about the different R&S OA antenna test solutions and how they are applicable for base station conformance testing.
