Definitions
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. The following condi­tions must be met:
FieldFox has been turned on for 10 minutes.
FieldFox is within its calibration cycle.
FieldFox remains at a stable surrounding environment temperature (between
-10 to 55 °C) for 90 minutes prior to turn-on and during operation.
Typical (typ.)
Expected performance of an average unit at a stable temperature between 20 °C to 30 °C for 90 minutes prior to turn-on and during operation; does not include guardbands. It is not covered by the product warranty. The FieldFox must be within its calibration cycle.
Nominal (nom.)
A general, descriptive term or design parameter. It is not tested, and not covered by the product warranty.
Calibration
The process of measuring known standards to characterize an instrument’s systematic (repeatable) errors.
Corrected (residual)
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.

Information
Full 12-term error correction. Corrects for directivity, source match, reflection frequency response, load match, and transmission frequency response for an N9923A with option 122, full two-port S-parameters. Unknown thru and QSOLT are both available.
Corrects for directivity, frequency response, and source match errors, using internal and external standards. QuickCal is most accurate for DUTs with 7/16 and Type-N connectors and measurement uncertainties are provided for frequencies ≤ 6 GHz. Reduced accuracy for DUTs with 3.5 mm (m), SMA (m), or other male coaxial connectors; performance is unspecified. QuickCal is not recommended for DUTs with 3.5 mm (f), SMA (f), or other similar female connectors. QuickCal is not applicable to waveguide.
