Verification Kit Overview
Verification Kit Overview
The Agilent 85057B 2.4 mm verification kit provides a set of standards with known
characteristics, traceable to a reference (golden) standard in Agilent Technologies
calibration lab. This set of standards is used to verify your measurement calibration and
also to verify that your network analyzer system is operating within its specifications. The
frequency range covered by the 85057B is from 45 MHz to 50 GHz.
Kit Contents
The 85057B verification kit includes the following items:
• 20 dB attenuator
• 40 dB attenuator
•25Ωmismatch airline
•50Ωairline
• data disks that contain factory-measured verification data.
Refer to Chapter 6, “Replaceable Parts,” for a complete list of contents and their associated
part numbers.
NOTE A file containing the verification data for your kit is maintained for one year
from the time of measurement. If you lose this data, see “Contacting Agilent”
on page 5-5 for a list of telephone numbers.
Compatible Network Analyzers
The 85057B verification kit is intended to be used with the 85056A 2.4 mm calibration kits
and any of the following Agilent network analyzers:
• 8510
• 872xSeries
•PNASeries
The verification data disk provided for use with each of the network analyzers listed above
contains the factory-measured S-parameter data for the devices in this kit. It also contains
the uncertainty limits used in the system verification procedure. This data is unique to
each kit.
NOTE A backup copy of each verification data disk and printout should be made
immediately upon receipt of this kit. Refer to your analyzers user’s guide for
instructions on duplicating a disk.

General Information
Incoming Inspection
Equipment Required but Not Supplied
Certain items are required or recommended for successful operation of the verification kit
but are not included in the kit. Refer to Table on page 6-2 for ordering information.
Incoming Inspection
Verify that the shipment is complete by referring to Table 6-1 on page 6-2.
Check for damage. The foam-lined storage case provides protection during shipping. Verify
that this case and its contents are not damaged.
If the case or any device appears damaged, or if the shipment is incomplete, refer to
“Contacting Agilent” on page 5-5. Agilent will arrange for repair or replacement of
incomplete or damaged shipments without waiting for a settlement from the
transportation company. Refer to “Returning a Kit or Device to Agilent Technologies” on
page 5-4 for instructions.
Recording the Device Serial Numbers
In addition to the kit serial number, the devices in this kit are individually serialized
(serial numbers are labeled into the body of each device). Record these serial numbers in
Table 1-1. Recording the serial numbers will prevent confusing the devices in this kit with
similar devices from other kits.

General Information
Clarifying the Terminology ofa Connector Interface
Clarifying the Terminology of a Connector Interface
In this document and in the prompts of the PNA calibration wizard, the sex of connectors
and adapters is referred to in terms of the center conductor. For example, a connector or
device designated as 1.85 mm –f– has a 1.85 mm female center conductor.
8510-series, 872x, and 875x ONLY: In contrast, during a measurement calibration, the
network analyzer softkey menus label a 1.85 mm calibration device with reference to the
sex of the analyzer’s test port connector—not the calibration device connector. For example,
the label SHORT(F) refers to the short that is to be connected to the female test port. This
will be a male short from the calibration kit.
A connector gage is referred to in terms of the connector that it measures. For instance, a
male connector gage has a female connector on the gage so that it can measure male
devices.
Preventive Maintenance
The best techniques for maintaining the integrity of the devices in this kit include:
• routine visual inspection
• cleaning
• proper gaging
• proper connection techniques
All of these are described in Chapter 3. Failure to detect and remove dirt or metallic
particles on a mating plane surface can degrade repeatability and accuracy and can
damage any connector mated to it. Improper connections, resulting from pin depth values
being out of specification (see Table 2-2 on page 2-4), or from bad connection techniques,
can also damage these devices.

Temperature—What To Watch Out For
Due to the small dimensions of the devices, electrical characteristics will change with
temperature.Therefore,the operating temperature is a critical factor in their performance,
and must be stable before use.
IMPORTANT Avoid unnecessary handling of the devices during use because your fingers
are a heat source.

Mechanical Characteristics
Mechanical Characteristics
Mechanical characteristics such as center conductor protrusion and pin depth are not
warranted performance specifications. They are, however, important supplemental
characteristics related to electrical performance. Agilent Technologies verifies the
mechanical characteristics of the devices in this kit with special gaging processes and
electrical testing. This ensures that the device connectors do not exhibit any improper pin
depth when the kit leaves the factory.
“Gaging Connectors” on page 3-7 explains how to use gages to determine if the kit devices
have maintained their mechanical integrity. Refer to Table 2-2, “Connector Pin Depths,”
for allowable recession.
Pin Depth
Pin depth is the distance the center conductor mating plane differs from being flush with
the outer conductor mating plane. See Figure 2-1. The pin depth of a connector can be in
one of two conditions:
•Protrusion is the condition in which the center conductor extends beyond the outer
conductor mating plane. This condition will indicate a positive value on the connector
gage.
•Recession is the condition in which the center conductor is set back from the outer
conductor mating plane. This condition will indicate a negative value on the connector
gage.

Mechanical Characteristics
Supplemental Characteristics
The following tables list the dimensions of the 50Ωairline and the 25Ωmismatch airline.
These are supplemental mechanical characteristics, and from these characteristics you can
calculate expected electrical performance.
Using these mechanical dimensions, you can calculate the expected electrical performance
with the equations in the following publications:
• Nelson, Robert E., and Marlene R. Coryell, "Electrical Parameters of Precision, Coaxial,
Air-Dielectric Transmission Lines", U.S. National Bureau of Standards Monograph No.
96.
• Somlo, P.I., "The Computation of Coaxial Line Step Capacitances", IEEE Transactions
on Microwave Theory and Techniques, Volume MTT-15, No. 1, January, 1967.
The measurement method in these publications provides a general idea of the expected
device characteristic impedance. Variations in connector interfaces can have a large effect
on your actual electrical measurements.
