For measurements of non-connectorized devices, test fixtures, probes or other structures are used to adapt from the coaxial interface of the test setup to the device under test (DUT). For accurate measurements of the DUT, these lead-ins and lead-outs need to be characterized, so that their effects can be mathematically removed, i.e. de-embedded from the measurement results.This application note provides practical hints to accurately characterize and de-embed these lead-in and lead-out structures with R&S Vector Network Analyzers ZNA, ZNB, ZNBT and ZND. As de-embedding is also essential in other test equipment like oscilloscopes, etc., this guide also describes, how lead-ins and lead-outs can be accurately characterized with a VNA and then exported as an S-Parameter file to be used by other test instruments.

The topic of this application note is mobile phone measurements – in theory and in practice. It discusses measurements according to the most common standard in use today, GSM.The first, theoretical portion of this application note covers digital modulation and access methods in general. This is followed by an overview of the specific characteristics of the GSM standard as well as a summary of the most important mobile radio measurements.The second, practical portion of this application note covers some of these measurements in detail and runs through them step by step. These measurements can be performed by small groups in labs.The measurements and analysis of the results are intended to illustrate the theoretical portion of the application note and to deepen the reader's understanding.All measurements are performed using the R&S®CMW500 wideband radio communication tester and an off the shelf mobile phone.

The LTE technology as specified within 3GPP Release 8 was first commercially deployed by end 2009. Since then the number of operators implementing the technology is strongly increasing around the globe. LTE has become the fastest developing mobile system technology. The same way GSM and WCDMA have been enhanced with additional features over time, LTE is continuously worked on. Initial enhancements have been included in 3GPP Release 9 and are described in this white paper.
