General Information
Calibration Kit Overview
The HP 85058D 1.85 mm economy calibration kit is used to calibrate HP 8510 systems (such as
the HP 85109B) for measurements of components with 1.85 mm connectors up to 65 GHz. The
1.85 mm connector is designed such that it may be mated with 2.4 mm connectors.
The calibration kit consists of the following:
Oset opens and shorts, and broadband load terminations.
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 7mm ats on some of the components
.
Adata disk and tape that contain the calibration constants for the devices in the kit.
Option 002 adds the following:
Adata tape that contains the calibration constants of the devices in the kit for HP 8510A/B
systems
.
The standards in this calibration kit allow you to perform simple 1{ or 2{port and TRM
(thru{reect{match) calibrations
.
This manual describes the HP 85058D calibration kit and provides replacement part numbers
,
specications
,and procedures for using, maintaining and troubleshooting the kit.
Note
This manual assumes you know proper connector care
.If not, refer to
\Principles of Microwave Connector Care{Quick Refernece Card" located in the
back of this manual, refer to Chapter 7, \Replaceable P
arts", for the HP part
number if another copy is needed.
Or, contact your nearest HP sales oce for the customer training course:

Equipment Required but Not Supplied
Gage sets are required for measuring the connector pin depth. Gages and various connector
cleaning supplies are not supplied with this kit. (Refer to Chapter 7, \Replaceable Parts", for
ordering information.)
Serial Numbers
A serial number label is attached to this calibration kit. A typical kit serial number label
is shown in Figure 1-1. The rst four digits followed by a letter comprise the serial number
prex; the last ve digits are the sux, unique to each calibration kit.

Calibration Kits Documented in this Manual
This manual applies to any HP 85058D calibration kit whose serial prex is listed on the title
page
.
Device Serial Numbers
In addition to the kit serial number
,the devices in this kit are individually serialized (serial
numbers are either labeled on or scribed onto the body of each device). Record these serial
numbers in Table 1-1. This can help you avoid confusing the devices in this kit with similar
devices from other kits. Kit integrity is an important part of compliance with U.S. MIL{STD
45662A, should you need to comply with this standard. The adapters, though they are
serialized, are for measurement convenience only and are not regarded as devices requiring a
traceable path in order to comply with MIL{STD 45662A.

The foam{lined storage case provides protection during shipping. If the case or any device
appears damaged, contact the nearest Hewlett{P
ackard sales and service oce (see inside
the back cover of this manual). Hewlett{P
ackard will arrange for repair or replacement of
incomplete or damaged shipments without waiting for a settlement from the transportation
company
.When you send the kit or device to Hewlett{Packard, include aservice tag (found at
the end of this manual) on which you provide the following information:
Your company name and address.
A technical contact person within your company, and the person's complete phone number.
If you are returning a complete kit, include the model number and serial number.
If you are returning one or more devices
,include the part numbers and serial numbers
.
Indicate the type of service required.
Include any applicable information.
HP 85058D General Information 1-3

Slotted Connectors
The female connectors in this kit have slotted contacts, therefore, the devices are
instrument{grade. Unlike precision slotless connectors, the slotted contacts prevent the devices
from being classied as metrology{grade.
With slotted connectors, the connected male device partially determines the connector
impedance of the female device by aring the contact ngers and consequently varying the
diameter of the female center conductor. Precision slotless connectors prevent diameter
variations in the female center conductor, therefore allowing greater control over connector
impedance.
With the exception of the slotted contacts, the 1.85 mm connectors in this kit maintain all
other aspects of metrology{grade connectors such as pin depth, diametrical and electrical
tolerances. Although the uncertainties are greater than devices with precision slotless
connectors, a traceable path to primary dimensional standards can still be established.
Clarifying Connector Sex
In this manual, devices are referred to in terms of their connector
.F
or example
,amale open

.
Preventive Maintenance
The best techniques for maintaining the integrity of the devices in this kit include routine
visual inspection and cleaning, and proper gaging and connection techniques
.F
ailure 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 the
observed
limits (see T
able 4-1)or from poor connection
techniques
,can also damage these devices
.
Visual inspection, cleaning techniques
,proper gaging for pin depth, and connection techniques
are all described in Chapter 4, \Gaging and Making Connections."

Mechanical Characteristics
Center Conductor Protrusion and Pin Depth
Mechanical characteristics such as center conductor protrusion and pin depth are not
performance specications. They are, however, important supplemental characteristics related
to electrical performance. Hewlett{Packard veries 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 center conductor protrusion and have proper pin depth
when the kit leaves the factory.
Chapter 4, \Gaging and Making Connections", explains how to use the gages listed in Chapter
7, \Replaceable Parts", to determine if the kit devices have maintained their mechanical
integrity. (Refer to Table 4-1 for typical and observed pin depth limits.)

User Information
The Calibration Devices and Their Use
The HP 85058D 1.85 mm economy calibration kit contains three types of calibration devices
with both male and female connectors: 50 ohm broadband loads, oset short circuits, and
oset open circuits.
For measurement convenience, the kit also contains three 1.85 mm to 1.85 mm adapters. The
adapters are primarily intended for use in measuring non{insertable devices, but can also be
used as connector savers.
The following briey describes the design and construction of all the calibration kit devices.
Broadband Loads
The broadband loads are instrument{grade
,50 ohm terminations which have been optimized
for broadband performance up to 65 GHz.The rugged internal structure provides for highly
repeatable connections
.Adistributed resistive element on sapphire provides excellent stability
and return loss
.
Oset Opens and Shorts
The oset opens and shorts are built from parts which are machined to the current
state{of{the{art in precision machining. The oset short's inner conductors have aone{piece
construction, common with the shorting plane
.This construction provides for extremely
repeatable connections
.The
oset opens have inner conductors which are supported by a
strong, low{dielectric{constant plastic to minimize compensation values. Both the opens
and shorts are constructed so that the pin depth can be controlled very tightly
,thereby
minimizing phase errors
.The lengths of the osets in the opens and shorts are designed so
that the dierence in phase of their reection coecients is approximately 180 degrees at all
frequencies.
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
.The adapters are
designed so that their nominal electrical lengths are the same
, which allows them to be used in
calibration procedures for non{insertable devices (such as adapter removal).
