Specifications
18.08.2008 13:52:31
Specifications apply under the following conditions:
30 minute warm-up time at ambient temperature, specified environmental conditions met, 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.
Rohde & Schwarz devices are designed to operate safely at altitudes of up to 3000 meters above sea level. The devices can be
transported to an altitude of 4600 meters above sea level without damage.
