Rohde & Schwarz R&S ® FSH4/R&S ® FSH8/R&S ® FSH13/ R&S ® FSH20 Spectrum Analyzer 3
Specifications
Specifications apply under the following conditions:
15 minutes warm-up time at ambient temperature, specified environmental conditions met, calibration cycle adhered to.
Data without tolerances: typical values only. Data designated as “nominal” applies to design parameters and is not tested. Data
without tolerance limits is not binding.
