Technical Specifications

All specifications and characteristics apply over a 25° C ±5° C range (unless
otherwise stated) and 60 minutes after the instrument has been turned on.
Definitions
Specifications: Warranted performance. Specifications include guardbands to
account for the expected statistical distribution, measurement uncertainties,
and changes in performance due to environmental conditions.
Characteristics: A performance parameter that the product is expected to meet
before it leaves the factory, but is not verified in the field, and is not covered
by the product warranty. A characteristic includes the same guardbands as a
specification.
Typical: Expected performance of an average instrument which does not
include guardbands. It is not covered by the instrument’s warranty.
Nominal: A general, descriptive term that does not imply a level of performance. It is not covered by the instrument’s warranty.
Supplemental information: may include typical, nominal or characteristic values.
Calibration is 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 primarily by the quality of the calibration
standards and how well “known” they are, plus the effects of system
repeatability, stability, and noise.
Uncorrected (raw) performance: Indicates performance without error
correction (calibration). Uncorrected performance affects the stability of a
calibration — the better the raw performance, the more stable the calibration.
