Specifications and Characteristics
Specifications: Terminology and Definitions
The following terms and definitions apply to Keysight’s N755xA series of ECal
modules. The definitions are specific to these modules and are not necessarily
valid definitions for other Keysight Technologies products.
Table 5-1 Specifications and Characteristics Terminology
Terms
Definitions
Operating Temperature Range
The temperature range over which the ECal modules maintain conformance to
their specifications.
Error-Corrected Temperature Range
The allowable network analyzer ambient temperature drift during
measurement calibration and during measurements when network analyzer
correction is turned on. It is also the range over which the network analyzer
maintains its specified performance while correction is turned on. If this
temperature range is exceeded, the error-corrected performance of the
network analyzer is degraded.
Measurement Calibration
This calibration determines the corrections necessary for accuracy-enhanced
(correction on) measurements.
Connector Pin Depth Values
Pin depth is a relative measurement value between the center conductor and
outer conductor mating surfaces. All references to pin depth in this manual
treat positive (+) values as protrusions of the center conductor, and negative
(–) values as recessions of the center conductor. See
Electrical Specifications
Warranted performance. Specifications include guard bands to account for the
expected statistical distribution, measurement uncertainties, and changes in
performance due to environmental conditions. Included with Option UK6.
Characteristic Performance
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 guard bands as a specification.
Typical Corrected Performance
Expected performance of an average unit which does not include guard bands.
It is not covered by the product warranty.
