2 Rohde & Schwarz R&S ® ESCI/ESCI7 EMI Test Receiver
Specifications
Specifications apply under the following conditions: 15 minutes warm-up time at ambient temperature, specified environmental
conditions met, calibration cycle adhered to, and all internal automatic adjustments performed. Data without tolerances: typical values
only. Data designated 'nominal' applies to design parameters and is not assured by Rohde & Schwarz.
