Agilent Technologies Inc. has announced the availability of its Signal Studio for 3GPP Long Term Evolution (LTE) software.

Designed to work with Agilent's N5182A MXG and E4438C ESG vector signal generators, Signal Studio software helps wireless R&D and manufacturing engineers create Agilent-validated and performance-optimised signals to design and test evolving 3GPP LTE products for the next-generation of mobile communications. The 3GPP LTE standard is intended to provide a framework for the evolution of 3G towards a high-data-rate, low-latency and packet-optimised radio-access technology, thus enabling significant new opportunities in mobile TV and video.

Agilent's Signal Studio is powerful, PC-based software for creating standards-based LTE signals. An easy-to-use user interface simplifies signal creation via familiar tree-style navigation of the signal structure. Before releasing its software, Agilent validates the signals generated by the software with industry experts to ensure they are correct, even in situations where the standards are not yet clearly defined. Used with Agilent's vector signal generators, these signals help engineers better characterise, evaluate and fine-tune their designs under parametric and functional test conditions.

Signal Studio provides spectrally correct signals tailored for testing and evaluating components such as power amplifiers used in LTE mobile handsets and base transceiver stations. Because the signals are spectrally correct, they emulate real-world signals (such as having the proper bandwidth, peak-to-average ratio and spectral shape). The software also supports importing a user file with data that has been pre-coded to simulate transport layer coding, enabling early receiver design and test.

The software features the ability to adjust LTE parameters to fine-tune signal characteristics for specific applications. Some of the key parameters that can be adjusted include bandwidth (1.25-, 2.5-, 5-, 10-, 15- or 20MHz), modulation type (QPSK, 16QAM or 64QAM), number of channels, type of channels (such as data or control), channel power level, payload data and resource block allocation, among others. With this flexibility, the engineer can test and optimise component performance over a wide range of operating conditions, including situations with few users or many users transferring data at different rates.

An early release of Agilent's N7624B Signal Studio for 3GPP LTE software is now available. Pricing for the N7624B-SW1?signal studio for 3GPP LTE, connectivity to E4438C ESG starts at Rs.1.63 lakh ($4,000) each. Meanwhile, the N7624B-SW3 signal studio for 3GPP LTE, connectivity to N5182A MXG sells at Rs.1.22 lakh ($3,000).
