Spectrum and modulation measurements on OFDMA WiBro signals
Key Facts With the R&S®FSP-K93 application firmware, the R&S®FSP spectrum analyzer can be used for spectrum and modulation measurements on OFDMA WiBro signals in accordance with the IEEE 802.16e-2005 standard, also known as WiMAX. Its functions cover standard related tests. The R&S®FSP equipped with the R&S®FSP-K93 option is the ideal partner for both development and production, featuring the smallest level measurement uncertainty in its class, as well as excellent RF characteristics. All functions can be operated manually or programmed via GPIB or LAN.
