Definitions
Definitions
All specifications and characteristics apply over a 25 °C ±5 °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.
Option 011: This includes all options available with Option 011 unless noted otherwise.

Corrected System Performance
The specifications in this section apply for measurements made using 10 Hz IF bandwidth,
no averaging, and at an environmental temperature of 25 ±5 °C, with less than 1°C
deviation from the calibration temperature. Assumes that an isolation calibration was
performed with an averaging factor of 16.
