Test and Measurement
At Mobile World Congress Rohde & Schwarz and Elektrobit will team up to present what is claimed to be the world’s first live demonstration of high-power user equipment testing.
Narda Safety Test Solutions has equipped the second generation of its Interference and Direction Analyzer with I/Q analyzer functions.
Anite has been selected to supply additional device testing systems to a major Chinese mobile operator for its TD-LTE device acceptance programme.
The new R&S SMW-K541 digital predistortion option from Rohde & Schwarz allows users to import predistortion coefficient tables directly into the R&S SMW200A high-end vector signal generator.
Anite has launched a major multi-link emulation enhancement to its Propsim channel emulator platform, significantly increasing the performance testing capacity of LTE-Advanced multi-mode chipsets, devices and base stations.
Anritsu has worked with Qualcomm Technologies Inc. to successfully demonstrate peak throughput for a Category 6 LTE device and network simulator using 20+20 MHz Carrier Aggregation.
Rohde & Schwarz has expanded the analysis bandwidth for its R&S FSW high-end signal and spectrum analyzers, claiming to be the first company to offer analysis bandwidth of 500 MHz.
Chalmers University has selected Anrtisu’s ME7838A broadband mm-wave test system to provide measurements supporting the development of new, high-frequency devices and components.
AT4 wireless has selected SAS, Anite’s interoperability and performance test solution, for advanced and rapid LTE device verification related to operator acceptance schemes.
Average peak throughputs as high as 144 Mbps were recorded in TeliaSonera’s commercial 4G network using Anite’s Nemo Outdoor test platform and a Cat 4 LTE test terminal Samsung Galaxy Note 3.

Solutions for LTE Design and Verification Enabling fast, accurate and efficient functional testing of LTE user equipment
This paper is designed to help network engineers, network planners, and network operations understand how to deploy Precision Time Protocol (PTP, or IEEE 1588). PTP is a next generation, packetbased timing protocol targeted for use in asynchronous network infrastructures based on packet transport technologies.
This field brief will discuss phase-matching cables, S-parameter definitions as they apply to cable characterization and other cable parameters such as Phase Shift and Group Delay. Advanced Time-Domain measurements will also be presented as enhancements to the well-known Distance-to-Fault (DTF) techniques. In addition, diagnostic tools like the Smith Chart will be briefly described.
To amplify weak signals received by the antenna in communication systems, low noise amplifiers (LNAs) are deployed. LNAs are used in various applications such as GPS receivers, wireless data systems, satellite communications, cellular handsets, radio systems, etc.
RF transmitters are an essential part of modern communications. Designed and assembled from core RF components, RF transmitters have many different forms and applications. We often think of RF transmitters in wireless communications, but the concept applies equally to wired applications such as cable television.
