The R&S®FS-K72 application firmware can be installed on all models of the R&S®FSQ, R&S®FSU, R&S®FSG, R&S®FSUP, R&S®FSMR, R&S®FMU and R&S®FSP signal and spectrum analyzers, enhancing the range of applications to include code domain power and modulation measurements on 3GPP FDD signals.
R&S®FS-K74 integrates into R&S®FS-K72 and extends the modulation measurement capabilities to HSDPA and HSUPA signals in the downlink for base stations.
R&S®FS-K74+ allows extented measurements in line with 3GPP Release 7, i.e. relative code domain error with 64QAM modulation.
