Rohde & Schwarz R&S ® ESL EMI Test Receiver 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 'nominal' applies to design
parameters and is not tested. Rohde & Schwarz equipment is designed for reliable operation up to an altitude of 3000 m above sea
level, and for transport up to an altitude of 4600 m above sea level.
