Application Note: This application note highlights various aeronautical radio navigation signals such as VHF omni directional radio range (VOR), instrument landing system (ILS) for glide slope (GS) and localizer (LLZ), as well as marker beacon (MB). R&S® test and measurement solutions for avionics navigation... more
Application Note: The aim of channel sounding is to characterize a radio channel by decomposing the radio propagation path into its individual multipath components. This application note provided by Neul describes how channel sounding can be performed using the R&S SMBV100A Vector Signal Generator and the R&S FSL... more
Webcast: The first LTE FDD networks have been already launched and analysts expect that the first TD-LTE based network will follow in 2011. In contrast to third generation mobile communications systems the TDD mode follows FDD very closely with respect to standardization and base station and handset... more
White Paper: 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... more
White Paper: Multiple input multiple output (MIMO) technology is an integral part of 3GPP E-UTRA long term evolution (LTE). As part of MIMO, beamforming is also used in LTE. This white paper discusses the basics of beamforming and explains the eight MIMO transmission modes in LTE Release 9. Get the paper and... more
White Paper: Although the commercialization of LTE technology began in end 2009, the technology is still being enhanced in order to meet ITU-Advanced requirements. This white paper summarizes these necessary improvements, which are known as LTEAdvanced... more
White Paper: Near Field Communication (NFC) is a new short-range, standards-based wireless connectivity technology, that uses magnetic field induction to enable communication between electronic devices in close proximity. Based on RFID technology, NFC provides a medium for the identification protocols that... more
Application Note: This application note describes the noise figure measurement using the R&S Vector Network Analyzers of the ZVA and ZVT series. It explains the concept of measuring noise figure without the need for a characterized noise source. Furthermore, it discusses different measurement applications and the... more
Application Note: All digital oscilloscopes are temporarily blind. During this blind time the user will miss critical signal events at his device under test. Thus, it is necessary to understand the impact of blind time to the measurement. This application note explains the background of blind time and points out... more
