HP 8719/20/22ET Specifications and Characteristics
Definitions
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.
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 from a calibration kit to
characterize a network analyzer’s systematic (repeatable) errors.
Corrected (residual) Performance: 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) Performance: Indicates instrument performance without error
correction. The uncorrected performance affects the stability of a calibration.
Standard: When referring to the analyzer, this includes all options unless noted otherwise.
