16 Rohde & Schwarz R&S ® FSH4/R&S ® FSH8/R&S ® FSH13/ R&S ® FSH20 Spectrum Analyzer
R&S ® FSH-K47 1xEV-DO ® BTS pilot channel and EVM measurement
application
R&S
® FSH-K47E 1xEV-DO ® BTS PN scanner and time domain power
measurement application
The specifications below apply to the R&S ® FSH4 and R&S ® FSH8. They are based on the data sheet specifications of the R&S ® FSH4
and R&S ® FSH8, have not been checked separately and are not verified during instrument calibration. Measurement uncertainties are
indicated as 95 % confidence intervals. The specified level measurement errors do not take into account systematic errors due to
reduced signal-to-noise ratio (SNR).
