With the Rohde & Schwarz FSH-K46 option, the Rohde & Schwarz FSH is perfectly equipped for transmitter measurements on CDMA2000® base stations. In addition to the overall performance, the performance of the code channels "Pilot Channel" (F-PICH) and "Synchronization Channel" (F-SYNC) is determined. The frequency offset of the carrier frequency, as well as the EVM value and Rho are also measured and displayed. In this way, transmitter interference such as limits (clipping) or intermodulation can be recognized, which are difficult to detect in the spectrum.
