FSL-K91n WLAN IEEE 802.11n OFDM analysis
The specifications of the R&S ® FSL-K91 and R&S ® FSL-K91n options are based on the data sheet of the R&S ® FSL spectrum analyzer.
Specifications apply under the following conditions: 30 minutes warm-up time at ambient temperature, specified environmental
conditions met, calibration cycle adhered to, and all internal automatic adjustments performed. "Typical values" are designated with
the abbreviation "typ." These values are verified during the final test but are not assured by Rohde & Schwarz. "Nominal values" are
design parameters that are not assured by Rohde & Schwarz. These values are verified during product development but are not
specifically tested during production.
