Aug 18 2006 -- The Vector Signal Generator R&S SMJ100A in combination with the compact Spectrum Analyzer R&S FSL is a cost-efficient production measurement solution for WiMAX applications offered by Rohde & Schwarz.
Internal options allow users to perform tests in accordance with the IEEE 802.16-2004 and IEEE 802.16e-2005 standards. By using the Digital Standard WiMAX R&S SMJ-K49 option, users can generate signals on the physical layer for both mobile and stationary applications. The R&S FSL-K92 option includes all stationary WiMAX applications. For IEEE 802.16e, which is the mobile version of the WiMAX standard, the company offers an external solution for the R&S FSL.
WiMAX is a technology for broadband mobile radio applications and simultaneously a wireless alternative to DSL. It is based on modern transmission capabilities such as OFDM/OFDMA. The objective is to provide reliable access to high-speed Internet applications. Due to the trend toward mobile applications, WiMAX has a promising future. To ensure stable function, manufacturers of WiMAX instruments require a reliable measurement solution for production, says the company.
For the development of WiMAX, the company already has the successful high-end Vector Signal Generator R&S SMU200A and the high-quality Signal Analyzer R&S FSQ on the market. The WiMAX package consisting of the R&S SMJ100A and R&S FSL now provides a version that covers all requirements in production. Advantageously, the version for development as well as the one for production can both be remote-controlled and have the same user interface.
By using the internal R&S SMJ-K49 option, users can generate signals for mobile and stationary applications for the IEEE 802.16-2004 standard as well as for the current IEEE 802.16e-2005 standard. The new functionalities can be remote-controlled via LAN or GPIB. Moreover, the high speed at which frequencies and waveforms are changed means very short throughput time. The R&S SMJ also offers standard-compliant signals for receiver tests and high signal quality when performing amplifier tests.
The R&S FSL-K92 option of the Spectrum Analyzer R&S FSL allows users to perform measurements on WiMAX signals in accordance with the OFDM method even without an additional PC. It is possible to perform tests on OFDMA signals for mobile applications by using external Windows software. Remote control via LAN is also available. The measurement of modulation quality and all RF parameters such as adjacent-channel power or spectrum masks as well as high measurement speed make the R&S FSL 'unique in its price class' and significantly reduce throughput time in production, says the company.
