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 box1, 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

Calibration Kit Overview
frequency from ALL measured standards instead of using only the three standards specified in
the class definitions. If you are using a PNA, it is RECOMMENDED that you use Expanded
Math with the 85058B data-based model for the highest accuracy. Expanded Math has no
effect with the 85058E data-based model.
Polynomial Model
The polynomial models may be used with SmartCal (Guided) and the Unguided Mechanical
Calibration method of the PNA Cal Wizard. Polynomial models are less accurate than the
data-based models. The polynomial models define the calibration standards with traditional
four-term polynomial calibration standard modeling parameters. For the PNA, it is NOT
RECOMMENDED that the polynomial models be used if the most accurate results are desired.
If you’re calibrating over the full frequency range of the calibration kit, you may be prompted to
connect some calibration standards more than once. These standards are defined by using
multiple polynomial models to achieve the full frequency range of operation.
Unlike the data-based models, the polynomial models allow you to modify the definitions of
calibration standards like any other traditional model-based calibration kit. This is accomplished
with the Advanced Modify Cal Kit dialog box. For more information on modifying the definitions
of the calibration standards, refer to online PNA Help.
In the Modify Class Assignments dialog box, the “Expanded Math” feature is turned OFF by
default when a polynomial model is selected. It is NOT RECOMMENDED that you use
Expanded Math with a polynomial model unless the calibration kit includes overlapped banded
standards such as a sliding load.

85058B (Standard) Kit Contents
The 85058B (Standard) calibration kit contains the following:
• one pair (male and female) of an offset open
• one pair (male and female) of a lowband load
• four pairs (male and female) of offset shorts
• three adapters
• a 5/16 inch, 90 N–cm (8 in–lb) torque wrench for use on the 1.85 mm connectors
• an open–end wrench for the 8mm flats on some of the components
• two gage sets
• a 10x magnifying glass
Refer to Table 6-1 on page 6-3 and Figure 6-1 on page 6-5 for a complete list of kit contents
and their associated part numbers.
Lowband Loads
The best operating region of the load is from DC to 35 GHz. Performance degrades quickly
above 35 GHz.
Offset Opens and Shorts
The offset opens and shorts are built from parts that are machined to the current
state-of-the-art in precision machining. The offset short’s inner conductors have a one-piece
construction, common with the shorting plane. This construction provides for extremely
repeatable connections. The offset opens have inner conductors that are supported by a
strong, low-dielectric plastic to provide repeatability and reliability. Both the opens and shorts
are constructed so that the pin depth can be controlled very tightly, thereby minimizing phase
errors. The length of the offset opens is designed so that the difference in phase of their
reflection coefficients is approximately 180 degrees at all frequencies, with respect to offset
Short 1.
Different combinations of offset shorts using three different lengths are used to calibrate
frequency ranges from 35 to 50 GHz and from 50 to 67 GHz. The calibration coefficients for
these offset shorts are optimized for their applicable bandwidths.
How to Identify Devices The shorts, opens, and loads in the kit are identified by the number
of rings (or bands) around the body of the device.
• lowband loads have no rings or bands
• 5.4 mm offset short has 1 ring or band and is identified as Short 1

85058B/E 1-5
General Information
Calibration Kit Overview
• 6.3 mm offset short has 2 rings or bands and is identified as Short 2
• 7.12 mm offset short has 3 rings or bands and is identified as Short 3
• 7.6 mm offset short has 4 rings or bands and is identified as Short 4
• offset open has 1 ring and is designed to be 180 degrees out of phase with Short 1. In
addition, the offset open has a rounded edge to help distinguish it from the shorts (see
Figure 1-1).
Figure 1-1 OPEN Calibration Devices: 85058B and 85058E
Adapters
Like the other devices in the kit, the adapters are built to very tight tolerances to provide good
broadband performance and to ensure stable, repeatable connections.
85058E (Economy) Kit Contents
The 85058E (Economy) calibration kit contains the following:
• one pair (male and female) of an offset open, offset short, and a broadband termination
• three adapters
• a 5/16 inch, 90 N-cm (8 in-lb) torque wrench for use on the 1.85 mm connectors
• an open–end wrench for the 8 mm flats on some of the components
Refer to Table 6-1 on page 6-3 and Figure 6-2 on page 6-7 for a complete list of kit contents
and their associated part numbers.
Broadband Terminations
The broadband terminations are instrument-grade, 50terminations that have been optimized
for performance up to 67 GHz. The rugged internal structure provides for highly repeatable
connections. A distributed resistive element on sapphire provides excellent stability and return
loss. The smooth body of the broadband termination allows it to be easily distinguished from an
open and short.
Offset Opens and Shorts
The opens and shorts are built from parts that are machined to the current state-of the-art
precision machining.
The short’s inner conductors have a one-piece construction, common with the shorting plane.

General Information
Calibration Kit Overview
This construction provides for extremely repeatable connections.
The offset opens have inner conductors that are supported by a strong, low-dielectric plastic to
provide repeatability and reliability.
Both the opens and shorts are constructed so that the pin depth can be controlled very tightly,
thereby minimizing phase errors. The opens and shorts have offsets. The lengths of these
offsets are designed so that the difference in phase of their reflection coefficients is
approximately 180 degrees at all frequencies. The open has a rounded edge to help distinguish
it from the shorts (see Figure 1-1 on page 1-5).
Adapters
Like the other devices in the kit, the adapters are built to very tight tolerances to provide good
broadband performance and to ensure stable, repeatable connections.
Calibration Definitions
The calibration kit must be selected prior to performing a calibration. In addition, the calibration
definitions for the devices in the kit must be installed in the analyzer if not permanently stored in
the internal memory or hard drive.
The calibration definitions can be:
• recalled from the analyzer (if stored in internal memory or the hard drive)
• entered from the front panel (polynomial models only)
Class assignments and standard definitions may change as more accurate model and
calibration methods are developed. You can download the most recent class assignments and
standard definitions from Keysight’s Calibration Kit Definitions Web page at
http://na.support.keysight.com/pna/caldefs/stddefs.html.
Refer to online PNA Help for instructions on selecting the calibration kit, installing (if necessary)
the calibration definitions, and performing a calibration.
NOTE The 8510 network analyzer is no longer being sold or supported by Keysight.
However, you can download the 8510 class assignments and standard definitions
from Keysight’s Calibration Kit Definitions Web page at
http://na.support.keysight.com/pna/caldefs/stddefs.html
Equipment Required but Not Supplied
Gage sets (not provided with the 85058E), adapters, ESD protection devices, and various
connector cleaning supplies are not included in the calibration kit but are required to ensure
