Brief Description The R&S®FSQ-K94 application firmware enhances the capability of R&S®FSQ-K93 to include analysis of WiMAX™ MIMO signals for the R&S®FSQ and R&S®FSG. Numerous measurements as specified by the standards and a wide range of functions are therefore available at a keystroke. R&S®FSQ-K93 adds WiMAX™ options to the scope of functions provided by the R&S®FSQ, R&S®FMU and R&S®FSG analyzers. The R&S®FSQ-K93 application firmware allows TX measurements on OFDM and OFDMA signals in line with the WiMAX™ IEEE 802.16?2004 and IEEE 802.16e?2005 standards. All WiMAX™ measurement applications are fully remote-controllable via the IEC/IEEE bus or LAN, using SCPI commands. The operating concepts of the different analyzers are largely identical, including the IEC/IEEE bus commands. Analyzers supporting WiMAX™ measurements Rohde & Schwarz offers a wide range of signal and spectrum analyzers for WiMAX™ measurements. The R&S®FSQ-K94 option provides the same user interface for a wide range of different spectrum and signal analyzers, offering optimal solutions for every application. No additional time is needed for transfer of T&M equipment from R&S to production.
