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).
