Definitions
General
Product data applies under the following conditions:
• Three hours storage at ambient temperature followed by 60 minutes warm-up operation
• Specified environmental conditions met
• Recommended calibration interval adhered to
• All internal automatic adjustments performed, if applicable
• Unless stated otherwise, specifications apply to test ports and a nominal source power of –10 dBm
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.
Nominal values (nom.)
Characterize product performance by means of a representative value for the given parameter (e.g. nominal impedance). In contrast to
typical data, a statistical evaluation does not take place and the parameter is not tested during production.
Measured values (meas.)
Characterize expected product performance by means of measurement results gained from individual samples.
Uncertainties
Represent limits of measurement uncertainty for a given measurand. Uncertainty is defined with a coverage factor of 2 and has been
calculated in line with the rules of the Guide to the Expression of Uncertainty in Measurement (GUM), taking into account
environmental conditions, aging, wear and tear.
Typical data as well as nominal and measured values are not warranted by Rohde & Schwarz.

The dynamic range is defined as the difference between the actual maximum source power and the RMS value of the data trace of the transmission
magnitude, which is produced by noise and crosstalk with the test ports short-circuited. The specification applies at 10 Hz measurement bandwidth,
without system error correction. The dynamic range can be increased by using a measurement bandwidth of 1 Hz. Crosstalk does not limit the dynamic
range.
