Version 18.00, December 2017Definitions General Product data applies under the following conditions: Three hours storage at ambient temperature followed by 30 minutes warm-up operation Specified environmental conditions met Recommended calibration interval adhered to Specifications with limits Represent warranted product performance by means of a range of values for the specified parameter. These specifications are marked with limiting symbols such as <, ≤, >, ≥, ±, or descriptions such as maximum, limit of, minimum. Compliance is ensured by testing or is derived from the design. Test limits are narrowed by guard bands to take into account measurement uncertainties, drift and aging, if applicable. Specifications without limits Represent warranted product performance for the specified parameter. These specifications are not specially marked and represent values with no or negligible deviations from the given value (e.g. dimensions or resolution of a setting parameter). Compliance is ensured by design. Typical data (typ.) Characterizes product performance by means of representative information for the given parameter. When marked with <, > or as a range, it represents the performance met by approximately 80 % of the instruments at production time. Otherwise, it represents the mean value. Measured values (meas.) Characterize expected product performance by means of measurement results gained from individual samples. Typical data as well as measured values are not warranted by Rohde & Schwarz.
