LTE-A 8x8 MIMO signal-generation, analyzer
LTE-Advanced is the evolution of LTE to 4G. Standardization work was done as part of Release 10 of the 3GPP specification, with further enhancements in Release 11 and beyond. LTE-Advanced introduces a number of enhancements and new technologies to enable peak data rates of up to 1Gb/s in the downlink and 500Mb/s in the uplink. To achieve such a high peak data rate, LTE-Advanced supports a maximum bandwidth of 100MHz by aggregating up to five component carriers, each up to 20MHz wide, and improved multi-antenna techniques in both uplink and downlink. For downlink, LTE-Advanced introduces transmission mode 9, which enables Multiple-Input Multiple-Output (MIMO) with up to eight spatial streams and antennas.
Using the Signal Studio and 89600 VSA software, engineers can start testing physical layer implementations of LTE-Advanced devices with greater insight and confidence, while gaining a deeper understanding of the root causes of design problems. The multi-channel signal analyzer enables full analysis of LTE-Advanced standards on next-generation antennas, base stations and user equipment. Working with the 89600 VSA, it enables phase-synchronous and cross-channel measurements with up to eight RF channels in a single mainframe, noted Agilent.
In addition, Signal Studio's LTE-Advanced option allows design engineers to perform receiver tests with fully channel-coded waveforms, including support of Physical Uplink Control Channel (PUCCH) Format 3. The waveforms can be created for receiver bit-error-rate, block-error-rate, packet-error-rate, or frame-error-rate analysis in a range of applications (e.g., performance verification and functional testing of receivers during RF/baseband integration and system verification, and for coding verification of baseband subsystems). Agilent's LTE-Advanced signal-generation and analysis solutions with 8x8 MIMO test are available. The N7624B-TFP is a signal studio advanced LTE-Advanced FDD R10 (requires N7624B-HFP and -JFP) and costs $3,300. For the same price, the N7625B-TFP Signal Studio Advanced LTE-Advanced TDD R10 (requires N7625B-EFP and -JFP) is also available. The N7109A-C08 is a multi-channel signal analyzer, 8-channel configuration and can be had for $208,500. The 89601B-BHG features 89600 VSA software for LTE-Advanced FDD (requires 89601B-BHD LTE-FDD) and costs $3,600 while the 89601B-BHH touts 89600 VSA software for LTE-Advanced TDD (requires 89601B-BHE LTE-TDD) and is available for also $3,600.
