| Rohde and Schwarz FSL-K72 Specification |
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. |
