Key Facts The R&S®FSL-K82 application firmware enhances the application range of the R&S®FSL spectrum analyzer to include code domain power and modulation measurements on CDMA2000® signals for radio configurations 1 to 5 and 10. The R&S®FSL is the ideal tool for CDMA2000® base station transmitter measurements in service and production. The main application is the determination of the power in the individual code channels referred to as code domain power measurement. The power ratios between the individual channels, for example, can be checked for compliance with the nominal values. Moreover, this measurement is a very efficient tool for detecting transmitter impairments such as clipping or intermodulation that are not obvious from the spectrum alone.
Features & Benefits Equipped with the R&S®FSL-K82/R&S®FSL-K84, the R&S®FSL provides the functionality needed for base station testing as well as the related parameters:
  • Code domain power (code domain analyzer)
  • Code domain power versus time (R&S®FSL-K82 )
  • Power versus chip (R&S®FSL-K84)
  • Rho
  • Error vector magnitude (EVM)
  • Peak code domain error
  • Power versus symbol
  • Symbol constellation
  • Channel table
  • Code domain error power
For 1xEV-DO, the rho measurement is subdivided into several new measurements due to the time division structure:
  • RhoMAC
  • Rhodata
  • Rhopilot
  • Rhooverall-1
  • Rhooverall-2
