FSL-K72 3GPP FDD base station test

The specifications below are based on the data sheet specifications of the R&S

®

FSL spectrum analyzer and have not been checked

separately. Specifications apply under the following conditions: 15 minutes warm-up time at ambient temperature, specified
environmental conditions met, calibration cycle adhered to and internal calibration performed. Data with tolerances are measurement
uncertainties with a confidence level of 95 %. The specified level measurement errors do not take into account systematic errors due
to reduced S/N ratio.

PMU = permissible measurement uncertainty in line with test specification 3GPP TS 25.141.

The standard deviation

σ (T

sweep

) of Gaussian-distributed signals depends on the selected sweep time (T

sweep

). Increasing the sweep time decreases

the standard deviation (

σ).
