General Information
Calibration Kit Overview
Calibration Kit Overview
The Keysight 85058B (Standard) and 85058E (Economy) 1.85 mm calibration kits are used to
calibrate Keysight network analyzers up to 67 GHz for measurements of components with 1.85
mm connectors. The 1.85 mm connector is designed such that it may be mated with 2.4 mm
connectors.
The 85058B (Standard) is the more accurate of the two calibration kits, containing twelve
calibration standards. The 85058E (Economy) kit is less accurate, containing six calibration
standards.
The standards in these calibration kits allow you to perform simple 1- or 2-port and TRM
(thru-reflect-match) calibrations.
Two Models for Defining Calibration Standards
The 85058 family of calibration kits offers the following two models for defining calibration
standards:
• Data-based model
❏
PNA: 85058B and 85058E
• Polynomial model
❏
PNA: 85058BP and the 85058EP
The PNA family of analyzers offers both the data-based models and the polynomial models as
cal kit selections.
Data-Based Model
The data-based model (85058B or 85058E) of each calibration kit provides higher accuracy for
describing calibration standards than the polynomial model (85058BP or 85058EP). The
data-based nominal S-Parameter model for each calibration standard is generated by using a
theoretical derivation or a high accuracy S-Parameter measurement. These nominal
S-parameter models are stored as part of the data-based model. Errors that can be the result of
polynomial model approximations do not exist.
The data-based models may only be used with the SmartCal (Guided) Calibration method of
the Cal Wizard. Using the data-based models with the Unguided Calibration method of the Cal
Wizard is not allowed.
The data-based models may NOT be edited with the Advanced Modify Cal Kit dialog box.
Attempts to programmatically edit the definitions of the data-based-model calibration standards
will result in reported errors (i.e. SCPI Execution Error).
In the PNA’s Modify Calibration Class Assignments dialog box
1
, the “Expanded Math” feature is
turned ON by default when the 85058B data-based model is selected from a cal kit menu. In
order to achieve a more accurate calibration, Expanded Math uses the data at any given
1. Pathway to the Modify Calibration Class Assignments dialog box: Calibration > Advanced
Modify Cal Kit > Edit Kit > Class Assignments: Edit.
