Rohde & Schwarz has added a new suite of application firmware for WiMAX MIMO measurements in line with IEEE 802.16e-2005. The new R&S FSQ-K94 option is designed to run on the R&S FSQ and R&S FSG signal analyzers. It also supports a combination of several analyzers for testing up to 4x4 MIMO systems.
The R&S FSQ-K94 application firmware can be used for testing semiconductor components such as WiMAX MIMO chipsets, amplifiers and mixers, as well as complete products such as WiMAX base stations or pico stations.
A large number of measurements required for testing MIMO systems can be performed by means of a single vector signal analyzer. To test the interaction between the individual components, however, two instruments may sometimes be required. In this case, the user can combine several R&S FSQ or R&S FSG analyzers to create a flexible test solution made up of standalone signal analyzers for testing 4x4 MIMO
systems, for example.
The R&S FSQ-K94 application firmware for WiMAX MIMO measurements and the R&S FSQ-K93 application firmware for WiMAX SISO (single input single output) measurements, which has been on the market for some time, feature similar user interfaces and remote control commands. This reduces the time required for user training. Moreover, WiMAX MIMO measurements can easily be added to existing programs. Tried and tested R&S FSQ-K93 functions such as automatic demodulation or user-specific spectrum emission masks (SEM) are also provided in R&S FSQ-K94.
