LTE/LTE-Advanced FDD and TDD Measurement Applications

Expand the capabilities of your M9391A and M9393A PXIe vector signal analyzers (PXI VSAs) with Keysight Technologies' library of measurement applications - the same applications used to increase the capability and functionality of its X-Series signal analyzers. Eleven of the most popular applications are now available for use with Keysight's new M9393A PXIe performance VSA and the M9391A PXI VSA. When you combine the raw hardware speeds of the PXI VSAs and the X-Series measurement applications for modular instruments, you can test more products in less time, while ensuring measurement continuity from design to manufacturing.

The LTE/LTE-Advanced FDD and TDD measurement applications transform the PXI VSAs into 3GPP LTE/LTEAdvanced standard-based RF transmitter testers. The applications provide fast, one-button RF conformance measurements to help you design, evaluate, and manufacture your LTE and LTE-Advanced base stations (eNB) and user equipment (UE). The measurement applications closely follow the 3GPP standard, allowing you to stay on the leading edge of your design and manufacturing challenges.

Proven algorithms and a common user interface across the X-Series analyzers and modular PXI VSAs create a consistent measurement framework for signal analysis that ensures repeatable results and measurement integrity so you can leverage your test system software through all phases of product development. The LTE/LTE-Advanced measurement applications are two in a common library of several measurement applications. You can further extend your test assets by utilizing up to four PXI VSAs with one software license.

Keysight's X-Series applications for modular instruments also include a unique "Resource Manager" that provides direct access to PXI VSA hardware drivers for the fastest power and spectrum-based measurements, while simultaneously using the X-Series applications for fast modulation quality measurements and the 89600 VSA software for fast spectrum measurements.

LTE/LTE-Advanced FDD and TDD Overview

LTE is the long term evolution of 3GPP’s universal mobile telephone system (UMTS). The aim of LTE is to provide a new radio access technology focused on packet-switched data only. Multiple requirements are set to achieve increased downlink and uplink peak data rates, scalable channel bandwidths, spectral efficiency improvements, control/user-plane latency, and co-existence with legacy standards while evolving towards an all-IP network. LTE accommodates both paired spectrum for frequency division duplex (FDD) and unpaired spectrum for time division duplex (TDD) operation. There is a high degree of commonality between FDD and TDD modes. These two modes are coordinated in the sense that they both share the same underlying framework including radio access schemes orthogonal frequency division multiple access (OFDMA) for the downlink, and single-carrier frequency division multiple access (SC-FDMA) for the uplink. Both modes share a single radio-access specification, equally applicable to paired and unpaired spectrum. There are some significant differences in specifications between FDD and TDD, most notably on the physical layer in the frame structure. There are few differences on the higher layers.

LTE-Advanced is not a new technology, instead it is an evolution step in the continuing development of LTE. It was initially specified as part of Release 10 of the 3GPP standard with continued evolution with additional features in Release 11 and more upcoming features in Release 12 and beyond. The three key LTE-Advanced technologies that are essential for meeting the ITU 4G requirements are: carrier aggregation, enhanced uplink multiple access, and enhanced multiple antenna transmission. Carrier aggregation is one of the key features of LTE-Advanced and the earliest deployed technologies of LTE-Advanced. It allows two or more (up to 5) component carriers to be aggregated in both contiguous and non-contiguous configurations in order to support up to 100 MHz transmission bandwidth.
