Differential devices offer advantages like noise immunity, low crosstalk, high integration density, and reduced power consumption. However, they also require special measurement capabilities. There are essentially two different measurement methods available: virtual measurements, and true differential measurements.
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.
With the recent introduction of the R&S®SMW200A microwave vector signal generator, Rohde & Schwarz now offers a novel approach to flexibly and conveniently generate multiple radar target echoes for systems up to 20 GHz. When used in combination with the R&S®FSW signal and spectrum analyzer, these commercial off-the-shelf (COTS) test instruments can be configured to support flexible radar target generation including range and target velocity emulation.
