Calibration Kit Overview
Calibration Kit Overview
The Agilent 85050D 7 mm calibration kit is used to calibrate Agilent network analyzers up
to 18 GHz for measurements of components with 7 mm connectors.
The standards in this calibration kit allow you to perform simple 1- or 2-port and TRM
(thru–reflect–match) calibrations.
This manual describes the 85050D calibration kit and provides replacement part numbers,
specifications, and procedures for using, maintaining, and troubleshooting the kit.
Kit Contents
The 85050D calibration kit includes the following items:
• user’s and service guide
• open, short, and broadband load terminations
• 3/4 in, 135 N-cm (12 in-lb) torque wrench for use on the 7-mm connectors
• a data disk that contains the calibration definitions of the devices in the kit for the 8510
systems
• a data disk set that contains the specifications and performance verification data for the
8510 systems
Refer to Table 6-1 on page 6-2 for a complete list of kit contents and their associated part
numbers.

Opens and Shorts
The opens and shorts are built from parts that are machined to the current state-of-the-art
in precision machining.
The shorts have a one-piece shorting plane that combines the inner and outer conductors.
The construction provides for extremely repeatable connections.
1- 2 85050D
General Information
Calibration Kit Overview
The opens have a low-dielectric collet depressor that is flush with the outer conductor.
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 offsets in the opens and shorts
are designed so that the difference in phase of their reflection coefficients is approximately
180 degrees at all frequencies.
Broadband Load
The broadband load is a metrology-grade termination that has been optimized for
performance up to 18 GHz. The rugged internal structure provides for highly repeatable
connections. A distributed resistive element on sapphire provides excellent stability and
return loss. The broadband load is a valid substitute for a lowband load.
Calibration Definitions
The calibration kit must be selected and the calibration definitions for the devices in the
kit installed in the network analyzer prior to performing a calibration. Refer to your
network analyzer user’s guide for instructions on selecting the calibration kit and
performing a calibration.
The calibration definitions can be:
• resident within the analyzer
• loaded from the provided disk
• entered from the front panel
Installation of the Calibration Definitions
The calibration definitions for the kit may be permanently installed in the internal
memory or hard disk of the network analyzer.
If the calibration definitions for the kit are not permanently installed in the network
analyzer, they must be manually entered. Refer to your network analyzer user’s guide for
instructions.
Equipment Required but Not Supplied
Connector cleaning supplies and various electrostatic discharge (ESD) protection devices
are not supplied with the calibration kit but are required to ensure successful operation of
the kit. Refer to
Table 6-1 on page 6-2 for ordering information.

Calibration Kit History
This section describes calibration kits with serial number prefixes lower that the ones
listed on the title page.
85050D Kits with Serial Prefix 3027A
These calibration kits did not have the calibration definitions disk to support the Agilent
8510C network analyzer. The part numbers provided in this manual are the recommended
replacement parts for these kits. The devices in these kits should meet the specifications
published in this manual.
Preventive Maintenance
The best techniques for maintaining the integrity of the devices in the kit include:
• routine visual inspection
• cleaning
• proper gaging
• proper connection techniques
All of these are described in Chapter 3 , “Use, Maintenance, and Care of the Devices.”
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 the observed limits (see
on page 2-5) or from bad connection techniques, can also damage these devices.
Table 2-2
When to Calibrate
A network analyzer calibration remains valid as long as the changes in the systematic
error are insignificant. This means that changes to the uncorrected leakages (directivity
and isolation), mismatches (source match and load match), and frequency response of the
system are small (<10%) relative to accuracy specifications.
Change in the environment (especially temperature) between calibration and
measurement is the major cause in calibration accuracy degradation. The major effect is a
change in the physical length of external and internal cables. Other important causes are
dirty and damaged test port connectors and calibration standards. If the connectors
become dirty or damaged, measurement repeatability and accuracy is affected.
Fortunately, it is relatively easy to evaluate the general validity of the calibration. To test
repeatability, remeasure one of the calibration standards. If you can not obtain repeatable
measurements from your calibration standards, maintenance needs to be performed on the
test port connectors, cables and calibration standards. Also, maintain at least one sample

of the device under test or some known device as your reference device. A verification kit
may be used for this purpose. After calibration, measure the reference device and note its
responses. Periodically remeasure the device and note any changes in its corrected
response which can be attributed to the test system. With experience you will be able to see
changes in the reference responses that indicate a need to perform the measurement
calibration again.

Temperature—What to Watch Out For
Changes in temperature can affect electrical characteristics. Therefore, the operating
temperature is a critical factor in performance. During a measurement calibration, the
temperature of the calibration devices must be stable and within the range shown in
Table 2-1.
IMPORTANT
Avoid unnecessary handling of the devices during calibration because your
fingers are a heat source.

Specifications
Mechanical Characteristics
Mechanical Characteristics
Mechanical characteristics such as center conductor protrusion and pin depth are not
performance specifications. They are, however, important supplemental characteristics
related to electrical performance. Agilent Technologies verifies the mechanical
characteristics of the devices in the kit with special gaging processes and electrical testing.
This ensures that the device connectors do not exhibit any center conductor protrusion or
improper pin depth when the kit leaves the factory.
“Gaging Connectors” on page 3-6 explains how to use gages to determine if the kit devices
have maintained their mechanical integrity. Refer to Table 2-2 on page 2-5 for typical and
observed pin depth limits.
Pin Depth
Pin depth is the distance the center conductor mating plane differs from being flush with
the outer conductor mating plane. See
one of two states: either protruding or recessed.
Figure 2-1. The pin depth of a connector can be in
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
The pin depth value of each calibration device in the kit is not specified, but is an
important mechanical parameter. The electrical performance of the device depends, to
some extent, on its pin depth. The electrical specifications for each device in the kit take
into account the effect of pin depth on the device’s performance.
Table 2-2 lists the typical
pin depths and measurement uncertainties, and provides observed pin depth limits for the
devices in the kit. If the pin depth of a device does not measure within the observed pin
depth limits, it may be an indication that the device fails to meet electrical specifications.

Use, Maintenance, and Care of the Devices
Electrostatic Discharge
Electrostatic Discharge
Protection against electrostatic discharge (ESD) is essential while connecting, inspecting, or
cleaning connectors attached to a static-sensitive circuit (such as those found in test sets).
Static electricity can build up on your body and can easily damage sensitive internal circuit
elements when discharged. Static discharges too small to be felt can cause permanent damage.
Devices such as calibration components and devices under test (DUT), can also carry an
electrostatic charge. To prevent damage to the test set, components, and devices:
• Always wear a grounded wrist strap having a 1 MΩ resistor in series with it when handling
components and devices or when making connections to the test set.
• Always use a grounded antistatic mat in front of your test equipment.
• Always wear a heel strap when working in an area with a conductive floor. If you are uncertain
about the conductivity of your floor, wear a heel strap.
• always ground yourself before you clean, inspect, or make a connection to a static-sensitive
device or test port. You can, for example, grasp the grounded outer shell of the test port or cable
connector briefly.
• always ground the center conductor of a test cable before making a connection to the analyzer
test port or other static-sensitive device. This can be done as follows:
1. Connect a short (from your calibration kit) to one end of the cable to short the center
conductor to the outer conductor.
2. While wearing a grounded wrist strap, grasp the outer shell of the cable connector.
3. Connect the other end of the cable to the test port.
4. Remove the short from the cable.
Figure 3-1 shows a typical ESD protection setup using a grounded mat and wrist strap. Refer to
Chapter 6 , “Replaceable Parts,” for information on ordering supplies for ESD protection.

Use, Maintenance, and Care of the Devices
Visual Inspection
Visual Inspection
Visual inspection and, if necessary, cleaning should be done every time a connection is made. Metal
particles from the connector threads may fall into the connector when it is disconnected. One
connection made with a dirty or damaged connector can damage both connectors beyond repair.
Magnification is helpful when inspecting connectors, but it is not required and may actually be
misleading. Defects and damage that cannot be seen without magnification generally have no effect
on electrical or mechanical performance. Magnification is of great use in analyzing the nature and
cause of damage and in cleaning connectors, but it is not required for inspection.
Look for Obvious Defects and Damage First
Examine the connectors first for obvious defects and damage: badly worn plating on the connector
interface, deformed threads, or bent, broken, or misaligned center conductors. Connector nuts
should move smoothly and be free of burrs, loose metal particles, and rough spots.
What Causes Connector Wear?
Connector wear is caused by connecting and disconnecting the devices. The more use a connector
gets, the faster it wears and degrades. The wear is greatly accelerated when connectors are not kept
clean, or are not connected properly.
Connector wear eventually degrades performance of the device. Calibration devices should have a
long life if their use is on the order of a few times per week. Replace devices with worn connectors.
The test port connectors on the network analyzer test set may have many connections each day, and
are, therefore, more subject to wear. It is recommended that an adapter be used as a test port saver
to minimize the wear on the test set’s test port connectors.
Inspect the Mating Plane Surfaces
Flat contact between the connectors at all points on their mating plane surfaces is required for a
good connection. See
and metal particles on the connector mating plane surfaces. Also look for signs of damage due to
excessive or uneven wear or misalignment.
Light burnishing of the mating plane surfaces is normal, and is evident as light scratches or
shallow circular marks distributed more or less uniformly over the mating plane surface. Other
small defects and cosmetic imperfections are also normal. None of these affect electrical or
mechanical performance.
If a connector shows deep scratches or dents, particles clinging to the mating plane surfaces, or
uneven wear, clean and inspect it again. Devices with damaged connectors should be discarded.

Cleaning Connectors
Clean connectors are essential for ensuring the integrity of RF and microwave coaxial connections.
1. Use Compressed Air or Nitrogen
WARNING
Use compressed air (or nitrogen) to loosen particles on the connector mating plane surfaces.
Clean air cannot damage a connector or leave particles or residues behind.
You can use any source of clean, dry, low-pressure compressed air or nitrogen that has an
effective oil-vapor filter and liquid condensation trap placed just before the outlet hose.
Ground the hose nozzle to prevent electrostatic discharge, and set the air pressure to less than
414 kPa (60 psi) to control the velocity of the air stream. High-velocity streams of compressed air
can cause electrostatic effects when directed into a connector. These electrostatic effects can
damage the device. Refer to
information.
2. Clean the Connector Threads
WARNING
Always use protective eyewear when using compressed air or nitrogen.

effective in detecting excessive center conductor protrusion or recession, and conductor damage on
DUTs, test accessories, and the calibration kit devices. Do not use the gages for precise pin depth
measurements.
Connector Gage Accuracy
The connector gages are only capable of performing coarse measurements. They do not provide the
degree of accuracy necessary to precisely measure the pin depth of the kit devices. This is partially
due to the repeatability uncertainties that are associated with the measurement. Only the
factory—through special gaging processes and electrical testing— can accurately verify the
mechanical characteristics of the devices.
With proper technique, the gages are useful in detecting gross pin depth errors on device
connectors. To achieve maximum accuracy, random errors must be reduced by taking the average of
at least three measurements having different gage orientations on the connector. Even the
resultant average can be in error by as much as ± 0.0001 inch due to systematic (biasing) errors
usually resulting from worn gages and gage masters. As the gages undergo more use, the
systematic errors can become more significant in the accuracy of the measurement.
Table 6-1 on page 6-2 for part number information. They are
When to Gage Connectors
Gage a connector at the following times:
• Prior to using a device for the first time: record the pin depth measurement so that it can be
compared with future readings. It will serve as a good troubleshooting tool when you suspect
damage may have occurred to the device.
NOTE
• If either visual inspection or electrical performance suggests that the connector interface may be
out of typical range (due to wear or damage, for example).
• If a calibration device is used by someone else or on another system or piece of equipment.
• Initially after every 100 connections, and after that as often as experience indicates.
When measuring pin depth, the measured value (resultant average of three or more
measurements) contains measurement uncertainty and is not necessarily the true
value. Always compare the measured value with the observed pin depth limits (which
account for measurement uncertainties) in
condition of device connectors.

Reading the Connector Gage
The gage dial is divided into increments of 0.0001 inch and major divisions of 0.001 inch (see Figure
3-2). For each revolution of the large dial, the smaller dial indicates a change of 0.01 inch. Use the
small dial as the indicator of multiples of 0.01 inch. In most connector measuring applications, this
value will be zero.
When making a measurement, the gage dial indicator will travel in one of two directions. If the
center conductor is recessed from the zero reference plane, the indicator will move counterclockwise
to indicate the amount of recession, which is read as a negative value. If the center conductor
protrudes, the indicator will move clockwise to indicate the amount of protrusion, which is read as
a positive value. Refer to
Figure 3-2 Reading the Connector Gage
“Pin Depth” on page 2-3 for definitions of protrusion and recession.

Use, Maintenance, and Care of the Devices
Gaging Connectors
Gaging Procedure
NOTE
Always hold a connector gage by the gage barrel, below the dial indicator. This gives
the best stability, and improves measurement accuracy.
1. Select the proper gage for your connector. Refer to Table 6-1 on page 6-2 for the gage part
number.
2. Inspect and clean the gage, gage master, and device to be gaged. Refer to “Visual Inspection” on
page 3-3 and “Cleaning Connectors” on page 3-4 of this chapter.
3. Zero the connector gage (refer to Figure 3-3):
a. While holding the gage by the barrel, and without turning the gage or the device, connect the
gage master to the gage. Refer to
“Connections” on page 3-10 for more information. Connect
the nut finger tight. Do not overtighten.
b. Using an open-end wrench to keep the gage from rotating, use the torque wrench
recommended for use with the kit to tighten the gage master connector nut to the specified
torque. Refer to
“Final Connection Using a Torque Wrench” on page 3-10 for more
information.
c. The gage pointer should line up exactly with the zero mark on the gage. If not, loosen the dial
lock screw on the gage and rotate the gage dial so that the pointer is aligned with the zero
mark.
d. Tighten the dial lock screw and remove the gage master.
e. Attach and torque the gage master to the gage once again to verify that the setting is
repeatable. Remove the gage master.
4. Gage the device connector (refer to Figure 3-3):
a. While holding the gage by the barrel, and without turning the gage or the device, connect the
gage master to the device. Refer to
“Connections” on page 3-10 for more information. Connect
the nut finger-tight. Do not overtighten.
b. Using an open-end wrench to keep the gage from rotating, use the torque wrench
recommended for use with the kit to tighten the device connector nut to the specified torque.
Refer to
c. Gently tap the barrel of the gage with your finger to settle the gage reading.
d. Read the gage indicator dial. If the needle has moved clockwise, the center conductor is

protruding by and amount indicated by the black numbers. If the needle has moved
counterclockwise, the center conductor is recessed by an amount indicated by the red
numbers.
For maximum accuracy, measure the connector a minimum of three times and take an
average of the readings. After each measurement, rotate the gage a quarter-turn to reduce
measurement variations that result from the gage or the connector face not being exactly
perpendicular to the center axis.
e. Compare the average reading with the pin depth specifications listed in Table 2-2 on page 2-5.
f. Remove the device from the gage.

Connections
Good connections require a skilled operator. The most common cause of measurement error is bad
connections. The following procedures illustrate how to make good connections.
How to Make a Connection
Preliminary Connection
1. Ground yourself and all devices. Wear a grounded wrist strap and work on a grounded,
conductive table mat. Refer to
2. Visually inspect the connectors. Refer to “Visual Inspection” on page 3-3.
3. If necessary, clean the connectors. Refer to “Cleaning Connectors” on page 3-4.
4. Use a connector gage to verify that all center conductors are within the pin depth specifications
in
Table 2-2 on page 2-5. Refer to “Gaging Connectors” on page 3-6.
5. Fully extend the connector sleeve on one of the connectors. Spin its knurled connector nut to
make sure the threads are fully extended. Fully retract the sleeve on the other connector. The
extended sleeve creates a cylinder into which the other connector fits.
“Electrostatic Discharge” on page 3-2 for ESD precautions.
If one of the connectors is fixed (such as on a test port), fully extend that connector sleeve and
fully retract the sleeve on the moveable connector.
6. Carefully align the connectors. As you make the actual connection, be sure the connectors align
perfectly.
7. Push the connectors straight together. Do not twist or screw the connectors together.
8. Engage the connector nut (of the connector with the retracted sleeve) over the threads of the
other connector (the connector with the extended sleeve). Turn only the connector nut. Let the
connector nut pull the two connectors straight together.
9. Do not overtighten this connection. A connection in which the outer conductors make gentle
contact at all points on both mating surfaces is sufficient. Very light finger pressure is enough to
accomplish this.
10.Make sure the connectors are properly supported. Relieve any side pressure on the connection
from long or heavy devices or cables.
Final Connection Using a Torque Wrench
Use a torque wrench to make a final connection. Table 3-1 provides information about the torque
wrench recommended for use with the calibration kit. A torque wrench is included in the calibration
kit. Refer to
Table 6-1 on page 6-2 for replacement part number and ordering information.

Use, Maintenance, and Care of the Devices
Connections
Using a torque wrench guarantees that the connection is not too tight, preventing possible
connector damage. It also guarantees that all connections are equally tight each time.
Prevent the rotation of anything other than the connector nut that you are tightening. It may be
possible to do this by hand if one of the connectors is fixed (as on a test port). However, it is
recommended that you use an open-end wrench to keep the body of the device from turning.
1. Position both wrenches within 90 degrees of each other before applying force. See Figure 3-4.
Wrenches opposing each other (greater than 90 degrees apart) will cause a lifting action which
can misalign and stress the connections of the devices involved. This is especially true when
several devices are connected together.
Figure 3-4 Wrench Positions
2. Hold the torque wrench lightly, at the end of the handle only (beyond the groove). See Figure 3-5.
Figure 3-5 Using the Torque Wrench
85050D
3- 11
Use, Maintenance, and Care of the Devices
Handling and Storage
3. Apply downward force perpendicular to the wrench handle. This applies torque to the connection
through the wrench.
Do not hold the wrench so tightly that you push the handle straight down along its length rather
than pivoting it, otherwise, you apply an unknown amount of torque.
4. Tighten the connection just to the torque wrench break point. The wrench handle gives way at
its internal pivot point. See
Figure 3-5. Do not tighten the connection further.
CAUTION
You don’t have to fully break the handle of the torque wrench to reach the specified
torque; doing so can cause the handle to kick back and loosen the connection. Any
give at all in the handle is sufficient torque.
How to Separate a Connection
To avoid lateral (bending) force on the connector mating plane surfaces, always support the devices
and connections.
CAUTION
1. Use an open-end wrench to prevent the device body from turning.
2. Use the torque wrench to loosen the connecting nut.
3. Complete the separation by hand, turning only the connecting nut.
4. Pull the connectors straight apart without twisting, rocking, or bending either of the connectors.
CAUTION
Do not turn the device body. Only turn the connector nut. Damage to the center
conductor can occur if the device body is twisted.
Do not twist one connector out of the other (like removing a light bulb). Turn the
connector nut, not the device body. Major damage to the center conductor can occur if
the device body is twisted.
Handling and Storage
• Install the protective end caps and store the calibration devices in the foam-lined storage case
when not in use.
• Never store connectors loose in a box, or in a desk or bench drawer. This is the most common
cause of connector damage during storage.
• Keep connectors clean.
• Do not touch mating plane surfaces. Natural skin oils and microscopic particles of dirt are easily
transferred to a connector interface and are very difficult to remove.
• Do not set connectors contact-end down on a hard surface. The plating and the mating plane
surfaces can be damaged if the interface comes in contact with any hard surface.

Performance Verification
Introduction
Introduction
The performance of your calibration kit can only be verified by returning the kit to Agilent
Technologies for recertification. The equipment required to verify the specifications of the
devices in the kit has been specially manufactured and is not commercially available.
How Agilent Verifies the Devices in Your Kit
Agilent verifies the specifications of these devices as follows:
1. The residual microwave error terms of the test system are verified with precision
airlines and shorts that are directly traced to the National Institute of Standards and
Technology (NIST). The airline and short characteristics are developed from mechanical
measurements. The mechanical measurements and material properties are carefully
modeled to give very accurate electrical representation. The mechanical measurements
are then traced to NIST through various plug and ring gages and other mechanical
measurements.
2. Each calibration device is electrically tested on this system. For the initial (before sale)
testing of the calibration devices, Agilent includes the test measurement uncertainty as
a guardband to guarantee each device meets the published specification. For
recertifications (after sale), no guardband is used and the measured data is compared
directly with the specification to determine the pass or fail status. The measurement
uncertainty for each device is, however, recorded in the calibration report that
accompanies recertified kits.
These two steps establish a traceable link to NIST for Agilent to the extent allowed by the
institute’s calibration facility. The specifications data provided for the devices in the kit is
traceable to NIST through Agilent Technologies.

Recertification
Recertification
The following will be provided with a recertified kit:
• a new calibration sticker affixed to the case
• a certificate of calibration
• a calibration report for each device in the kit listing measured values, specifications,
and uncertainties

Agilent Technologies offers a Standard calibration for the recertification of the kit. For
more information, contact Agilent Technologies. Refer to
A list of NIST traceable numbers may be purchased upon request to be
included in the calibration report.
“Contacting Agilent” on page 5-5.
How Often to Recertify
The suggested initial interval for recertification is 12 months or sooner. The actual need for
recertification depends on the use of the kit. After reviewing the results of the initial
recertification, you may establish a different recertification interval that reflects the usage
and wear of the kit.
NOTE
The recertification interval should begin on the date the kit is first used after
the recertification date.
