Some 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.
Calibration: The process of measuring known
standards to characterize a network analyzer’s
systematic (repeatable) errors.
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.
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.
Nominal (nom.): A general, descriptive term that
does not imply a level of performance. It is not
covered by the product warranty.
Specification (spec.): Warranted performance.
Specifications include guardbands to account for
the expected statistical performance distribution,
measurement uncertainties, and changes in perfor-
mance due to environmental conditions.
Standard: When referring to the analyzer, this
includes no options unless noted otherwise.
Typical (typ.): Expected performance of an average
unit, which does not include guardbands. It is not
covered by the product warranty.
Uncorrected (raw): Indicates instrument perfor-
mance without error correction. The uncorrected
performance affects the stability of a calibration.
