Definitions
All specifications and characteristics apply over a 23 °C ±3 °C range (unless otherwise
stated) and 1/2 hour after the instrument has been turned on.
Warranted performance. Specifications include guardbands to
Specification (spec.):
account for the expected statistical performance distribution, measurement uncertainties,
and changes in performance due to environmental conditions.
A performance parameter that the product is expected to meet
Characteristic (char.):
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.
Expected performance of an average unit which does not include
Typical (typ.):

Nominal (nom.):
is not covered by the product warranty.
The process of measuring known standards from a calibration kit to
Calibration:
characterize a network analyzer's systematic (repeatable) errors.
Indicates performance after error correction
Corrected (residual) Performance:
(calibration). It is determined by the quality of calibration standards and how well
"known" they are, plus system repeatability, stability, and noise.
Indicates instrument performance without error
Uncorrected (raw) Performance:
correction. The uncorrected performance affects the stability of a calibration.
When referring to the analyzer, this includes all options unless noted otherwise.
