It can be difficult when individual components could pass EMI testing but, as the components are combined into subsystems or into the final product, the DUT fails. Incorporating EMI shielding materials as part of an initial design is the most cost-effective way to prevent these last-minute issues during testing.
This application notes introduces the Multi-Standard Radio Analyzer function of the R&S FSW and shows how it performs the measurement on multi-standard radio transmitters. It reveals interactions caused by the coexistence of signals of different cellular standards and localizes the root cause. With an example of a base station signal consisting of three radio access technologies (GSM/WCDMA/LTE FDD) it shows how easy interactions can be found. The R&S FSW is the ideal tool for trouble shooting tasks with its combination of a large bandwidth and the versatile Multi-Standard Radio Analyzer in one measurement instrument.
This application note discusses a case in which a continuous impairment in the GSM 900 band was affecting a cell phone station’s performance, and how Narda’s IDA 2 interference and direction analyzer was able to help.
There is a driving need for more accurate and compact waveguide components at higher frequencies, while maintaining cost-effective solutions. This application note presents a handful of benchmark simulations of waveguide components performed with FEKO.
This application note briefly summarizes the history of SCPI and outlines in which fields of application a SCPI based test system software has still advantages over a driver (e.g. IVI) based approach.
