Atec Agilent-N5264A - Manual (Page 4)

Definitions
All specifications and characteristics apply over a 25 °C ±5 °C range (unless otherwise stated)
and 90 minutes after the instrument has been turned on.
Specification (spec.): Warranted performance. Specifications include guardbands to account
for the expected statistical performance distribution, measurement uncertainties, and changes
in performance due to environmental conditions.
Characteristic (char.): A performance parameter that the product is expected to meet before it
leaves the factory, but that is not verified in the field and is not covered by the product
warranty. A characteristic includes the same guardbands as a specification.
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.
Calibration: The process of measuring known standards to characterize a network analyzer's
systematic (repeatable) errors.
Corrected (residual): Indicates performance after error correction (calibration). It is
determined by the quality of calibration standards and how well "known" they are, plus system
repeatability, stability, and noise.
Uncorrected (raw): Indicates instrument performance without error correction. The
uncorrected performance affects the stability of a calibration.
Standard: When referring to the analyzer, this includes no options unless noted otherwise.
