02 | Keysight | E4991B Impedance Analyzer - Data Sheet
Definitions
Specification (spec.)
Warranted performance. All specifications apply at 23 °C ± 5 °C unless otherwise stated,
and 30 minutes after the instrument has been turned on. Speciications include guard
bands to account for the expected statistical performance distribution, measurement
uncertainties, and changes in performance due to environmental conditions.
Typical (typ.)
Expected performance of an average unit which does not include guardbands. It is not
covered by the product warranty.
Nominal (nom.)
A general, descriptive term that does not imply a level of performance. It is not covered
by the product warranty.
