General Information
Calibration Kit Overview
Calibration Kit Overview
The Agilent 85052D 3.5 mm calibration kit is used to calibrate Agilent network analyzers up to 26.5 GHz for measurements of components with 3.5-mm connectors.
Kit Contents
The 85052D calibration kit includes the following items:
• user’s and service guide
• offset opens and shorts, and broadband loads
• three 3.5 mm adapters
• 5/16 in, 90 N-cm (8 in-lb) torque wrench
• 7 mm open-end wrench
• data disk that contains the calibration definitions of the devices in the calibration kit
for 8510 systems.
• data disk set that contains the specifications and performance verification data for 8510
systems.
NOTE
For measurement convenience, the kit also contains three 3.5 mm adapters. The adapters are primarily intended for use in measuring non-insertable devices, but can also be used as a connector saver.
Refer to Chapter 6 for a complete list of kit contents and their associated part numbers.
Broadband Loads
The broadband loads are metrology-grade terminations that have been optimized for
performance up to 26.5 GHz. The rugged internal structure provides for highly repeatable
connections. A distributed resistive element on sapphire provides excellent stability and
return loss.
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.
A backup copy of each data disk and printout should be made immediately
upon receipt of the calibration kit. Refer to your analyzer user’s guide or
embedded Help system for instructions on duplicating a disk.
The offset short’s inner conductors have a one-piece construction, common with the shorting plane. The construction provides for extremely repeatable connections.
The offset opens have inner conductors that 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 offsets in the opens and shorts
are designed so that the difference in phase of their reflection coefficients is approximately

General Information
Calibration Kit Overview
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.
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.
The calibration definitions can be:
• resident within the analyzer
• downloaded from the Web at http:na.tm.agilent.com/pna/caldefs/stddefs.html.
• loaded from the provided disk (8510 series network analyzers only)
• manually entered from the front panel
Refer to your network analyzer user’s guide or embedded Help for instructions on manually entering calibration definitions, selecting the calibration kit, and performing a calibration.
Equipment Required but Not Supplied
Some items are required or recommended for successful operation of your kit, but are not supplied with the kit. Refer to Table 6-2 on page 6-3 for a list of these items and for ordering information.

Incoming Inspection
Incoming Inspection
Refer to Chapter 6 to verify a complete shipment. Use Table 1-1 to record the serial numbers of all serialized devices in your kit.
Check for damage. The foam-lined storage case provides protection during shipping. 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. See "Returning a Kit or Device to Agilent," on page 5-4.
Recording the Device Serial Numbers
In addition to the kit serial number, the devices in the kit are individually serialized (serial numbers are labeled onto the body of each device). Record these serial numbers in
Table . Recording the serial numbers will prevent confusing the devices in this kit with
similar devices from other kits.
The adapters included in the kit are for measurement convenience only and are not serialized.

General Information
Precision Slotless Connectors
Precision Slotless Connectors
The female 3.5 mm connectors in this calibration kit are metrology-grade, precision
slotless connectors (PSC). A characteristic of metrology-grade connectors is direct
traceability to national measurement standards through their well-defined mechanical
dimensions.
Conventional female center conductors are slotted. When mated, the female center conductor is flared by the male pin. Because physical dimensions determine connector impedance, electrical characteristics of the female connector (and connection pair) are dependent upon the mechanical dimensions of the male pin. While connectors are used in pairs, their male and female halves are always specified separately as part of a standard, instrument, or device under test. Because of these facts, making precision measurements with the conventional slotted connector is very difficult, and establishing a direct traceability path to primary dimensional standards is nearly impossible.
The precision slotless connector was developed to eliminate these problems. All PSCs are
female. A PSC incorporates a center conductor with a solid cylindrical shell that defines
the outside diameter of the female center pin. Its outside diameter and, therefore, the
impedance in its region does not change. The inner part provides an internal contact that
flexes to accept the allowed range of male pin diameters.
The calibration of a network analyzer having a conventional slotted female connector on
the test port remains valid only when the device under test and all calibration standards
have identical male pin diameters. For this reason PSC test port adapters are supplied in
most calibration kits.
Precision slotless connectors have the following characteristics:
• There is no loss of traceable calibration on test ports when the male pin diameter of the
connector on the device under test is different from the male pin diameter of the
calibration standard.
• The female PSC and its mating male connector can be measured and specified
separately as part of the device either is attached to.
• All female connectors can have a known, stable impedance based only on the diameters
of their inner and outer conductors.
• Female calibration standards can be fully specified. Their specifications and
traceability are unaffected by the diameter of the male mating pin.
• A fully traceable performance verification is made using a precision 50 ohm airline
having a PSC.
• Measurement repeatability is enhanced due to non-changing connector characteristics
with various pin diameters.
With PSCs on test ports and standards, the percentage of accuracy achieved when
measuring at 50 dB return loss levels is comparable to using conventional slotted
connectors measuring devices having only 30 dB return loss. This represents an accuracy
improvement of about 10 times.

Clarifying the Terminology of a Connector Interface
Clarifying the Terminology of a Connector Interface
In this document and in the prompts of the PNA calibration wizard, the gender of cable
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.
Table 1-2 Clarifying the Sex of Connectors: Examples
Terminology Meaning
Short
–f–
Short (f) Male short (male center conductor) to be connected to female port
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.
Female short (female center conductor)
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. 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 Table 2-2 on page 2-4) or from bad connection techniques, can also damage these devices.

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.

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 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 Figure 2-1. The pin depth of a connector can be in one of two states: either protruding or recessed.
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.

Specifications
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. Refer to Figure 2-1 for a visual representation of proper pin depth (slightly recessed).

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, conductive table mat while making connections.
• 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.

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.
In some cases, magnification is necessary to see damage to a connector; a magnifying
device with a magnification of ≥10x is recommended. However, not all defects that are
visible only under magnification will affect the electrical performance of the connector. Use
the following guidelines when evaluating the integrity of a connector.
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 Figure 2-1 on page 2-3. Look especially for deep scratches or dents, and for dirt 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. Determine the cause of damage before connecting a new, undamaged
connector in the same configuration.
85052D 3-3
Use, Maintenance, and Care of the Devices
Cleaning Connectors
Inspect Female Connectors
Inspect the contact fingers in the female center conductor carefully. These can be bent or broken, and damage to them is not always easy to see. A connector with damaged contact fingers will not make good electrical contact and must be replaced.
NOTE
The female 3.5 mm connectors in this calibration kit are metrology-grade, precision
slotless connectors (PSC). Precision slotless connectors are used to improve accuracy. With
PSCs on test ports and standards, the accuracy achieved when measuring at 50 dB return
loss levels is comparable to using conventional slotted connectors measuring devices
having only 30 dB return loss. This represents an accuracy improvement of about 10 times.
Conventional female center conductors are slotted and, when mated, are flared by the male
pin. Because physical dimensions determine connector impedance, this change in physical
dimension affects electrical performance, making it very difficult to perform precision
measurements with conventional slotted connectors.
The precision slotless connector was developed to eliminate this problem. The PSC has a
center conductor with a solid cylindrical shell, the outside diameter of which does not
change when mated. Instead, this center conductor has an internal contact that flexes to
accept the male pin.
This is particularly important when mating nonprecision to precision devices.
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 “Electrostatic Discharge” earlier in this chapter for additional information.

Always use protective eyewear when using compressed air or
nitrogen.
2. Clean the Connector Threads
Use, Maintenance, and Care of the Devices
Cleaning Connectors
WARNING
Keep isopropyl alcohol away from heat, sparks, and flame. Store in a
tightly closed container. It is extremely flammable. In case of fire, use
alcohol foam, dry chemical, or carbon dioxide; water may be
ineffective.
Use isopropyl alcohol with adequate ventilation and avoid contact
with eyes, skin, and clothing. It causes skin irritation, may cause eye
damage, and is harmful if swallowed or inhaled. It may be harmful if
absorbed through the skin. Wash thoroughly after handling.
In case of spill, soak up with sand or earth. Flush spill area with water.
Dispose of isopropyl alcohol in accordance with all applicable federal, state, and local environmental regulations.
Use a lint-free swab or cleaning cloth moistened with isopropyl alcohol to remove any dirt or stubborn contaminants on a connector that cannot be removed with compressed air or nitrogen. Refer to Table 6-2 on page 6-3 for a part number for cleaning swabs.
a. Apply a small amount of isopropyl alcohol to a lint-free cleaning swab.
b. Clean the connector threads.
c. Let the alcohol evaporate, then blow the threads dry with a gentle stream of clean,
low-pressure compressed air or nitrogen. Always completely dry a connector before
you reassemble or use it.
3. Clean the Mating Plane Surfaces
a. Apply a small amount of isopropyl alcohol to a lint-free cleaning swab.
b. Clean the center and outer conductor mating plane surfaces. Refer to Figure 2-1 on
page 2-3. When cleaning a female connector, avoid snagging the swab on the center
conductor contact fingers by using short strokes.
c. Let the alcohol evaporate, then blow the connector dry with a gentle stream of clean,
low-pressure compressed air or nitrogen. Always completely dry a connector before
you reassemble or use it.
4. Inspect
Inspect the connector to make sure that no particles or residue remain. Refer to “Visual
Inspection” on page 3-3.
85052D 3-5
Use, Maintenance, and Care of the Devices
Gaging Connectors
Gaging Connectors
The gages available from Agilent Technologies are intended for preventive maintenance
and troubleshooting purposes only. They are 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. See
Table 6-2 on page 6-3 for part number information.
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. The information in Table 2-2 on page 2-4 assumes new gages and gage masters. Therefore, these systematic errors were not included in the uncertainty analysis. As the gages undergo more use, the systematic errors can become more significant in the accuracy of the measurement.
The measurement uncertainties in Table 2-2 are primarily a function of the assembly materials and design, and the unique interaction each device type has with the gage. Therefore, these uncertainties can vary among the different devices. For example, note the difference between the uncertainties of the opens and shorts.
The observed pin depth limits in Table 2-2 add these uncertainties to the typical factory pin depth values to provide practical limits that can be referenced when using the gages. See “Pin Depth” on page 2-3. Refer to “Kit Contents” on page 1-2 for more information on the design of the calibration devices in the kit.
NOTE
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
Table 2-2 on page 2-4 to evaluate the condition of device connectors.

Use, Maintenance, and Care of the Devices
Gaging Connectors
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.)
• 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.

Use, Maintenance, and Care of the Devices
Gaging Connectors
Gaging Procedures
Gaging 3.5 mm Connectors
NOTE
Always hold a connector gage by the gage barrel, below the dial indicator.
This gives the best stability, and improves measurement accuracy. (Cradling
the gage in your hand or holding it by the dial applies stress to the gage
plunger mechanism through the dial indicator housing.)
1. Select the proper gage for your connector. Refer to Table 6-1 on page 6-2 for gage part numbers.
2. Inspect and clean the gage, gage master, and device to be gaged. Refer to “Visual
Inspection” and “Cleaning Connectors” earlier in this chapter.
3. Zero the connector gage (refer to Figure 3-2):
a. While holding the gage by the barrel, and without turning the gage or the device,
connect the gage to the gage master by interconnecting the male and female
connectors. Connect the nut finger tight. Do not overtighten.
b. Using an open-end wrench to keep the device body from rotating, use the torque
wrench included in the kit to tighten the connecting nut to the specified torque. Refer to “Final Connection Using a Torque Wrench” on page 3-10 for additional information.
c. As you watch the gage pointer, gently tap the barrel of the gage to settle the reading.
The gage pointer should line up exactly with the zero mark on the gage. If not, adjust the zero set knob until the gage pointer lines up exactly with the zero mark.
d. Remove the gage master.
4. Gage the device connector (refer to Figure 3-2):
a. While holding the gage by the barrel, and without turning the gage or the device,
connect the gage to the device by interconnecting the male and female connectors.
Connect the nut finger-tight. Do not overtighten.
b. Using an open-end wrench to keep the device body from rotating, use the torque
wrench included in the kit to tighten the connecting nut to the specified torque. Refer to “Final Connection Using a Torque Wrench” on page 3-10 for additional information.
c. Gently tap the barrel of the gage with your finger to settle the gage reading.
d. Read the gage indicator dial. Read only the black ± signs; not the red ± signs.
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 observed pin depth limits in Table 2-2 on page
2-4.

Connections
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 “Electrostatic Discharge” on page 3-2 for ESD precautions.
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 observed pin depth values in Table 2-2 on page 2-4. Refer to “Gaging Connectors” on page 3-6.
5. Carefully align the connectors. The male connector center pin must slip concentrically into the contact finger of the female connector.
6. Push the connectors straight together and tighten the connector nut finger tight.
CAUTION
Do not twist or screw the connectors together. As the center conductors mate, there is
usually a slight resistance.
7. The preliminary connection is tight enough when the mating plane surfaces make uniform, light contact. 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.
8. 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.
Do not turn the device body. Only turn the connector nut. Damage to the
center conductor can occur if the device body is twisted.

3-10 85052D
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 3-3. 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 3-3 Wrench Positions
2. Hold the torque wrench lightly, at the end of the handle only (beyond the groove). See
Figure 3-4.
Figure 3-4 Using the Torque Wrench
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.
85052D 3-11
Use, Maintenance, and Care of the Devices
Handling and Storage
4. Tighten the connection just to the torque wrench break point. The wrench handle gives way at its internal pivot point. See Figure 3-4 on page 3-11. 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 another open-end 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.
Do not turn the device body. Only turn the connector nut. 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.

85052D 4-1
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
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
NOTE
Agilent Technologies offers a Standard calibration for the recertification of the kit. For
more information, contact Agilent Technologies. Refer to “Contacting Agilent” on page 5-5
for a list of offices.
A list of NIST traceable numbers may be purchased upon request to be
included in the calibration report.
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.
Where to Send a Kit for Recertification
