In order to deal with electromagnetic interference (EMI) problems, the source of the unwanted emissions needs to be identified before a solution can be implemented. Testing at an EMC compliance laboratory can prove to be both slow and costly, and oftentimes, the information that comes back from the lab is a spectrum curve that indicates frequencies where emissions are critical of in violation of the limits.
One of the most critical steps in ensuring reliable, long-term wireless infrastructure operation is performing regular preventative maintenance. This application note discusses the challenges of keeping up VNAs for field use, as well as testing processes, adjustments, automation and programming.
This application note provides an overview of the MHL technology and also describes the Rohde & Schwarz compliance test solution for the system part of the current MHL2.0 standard version.
This application note describes Battery Life Measurements with the R&S®RT-ZVC02/04(A) MultiChannel Probe. The measurements are described mostly with the use of an oscilloscope. However, measurements are also possible with CMWRun and a corresponding communication tester.
Both resistive type and reactive type power divider/combiners can be used to fan-in or fan-out RF signals. However, both types distribute RF signals in a different fashion. This white paper offers guidelines and considerations for determining a divider/combiner for each application.
