09.00, July 2011 Rohde & Schwarz R&S®FSMR Measuring Receiver 3 Specifications Specifications apply under the following conditions: 30 minutes warm-up time at ambient temperature (60 minutes for RF level), specified environmental conditions met, calibration cycle adhered to, and total calibration performed. Data without tolerance limit is not binding. Data designated 'nominal' applies to design parameters and is not tested. Accuracy does not include mismatch error and errors due to standard deviation of the measurement readings, which are influenced by the number of averages.
