1General Information
Calibration Kit Overview
The Keysight 85056D 2.4 mm standard calibration kit and 85563A/85664A
3-in-1 2.4 mm calibration kits are used to calibrate Keysight network analyzers
up to 50 GHz for measurements of components with 2.4 mm connectors.
Kit Contents
Figure 1-1 85056D 2.4 mm calibration kit
The 85056D calibration kit includes the following items:
The 85563A 3-in-1 calibration kit includes the following items:
— offset open and short (female)
— broadband termination (female)
The 85564A 3-in-1 calibration kit includes the following items:
— offset open and short (male)
— broadband termination (male)
85563A and 85564A are mostly subsets of the 85056D calibration kit.
85563A and 85564A contain a single sex connector (i.e., female only or
male only). Also, while adapters are standard with the 85056D, they are
optional on the 85563A and 85564A.
The open and shorts are identical in the kits. For example, the open female
standard in the 85056D is the same open that is included in the 85563A.
The load standards are different parts that have the same electrical
performance.
Refer to Chapter 6, “Replaceable Parts,” for a complete list of kit contents and
their associated part numbers.
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, allowing them to be used in calibration procedures for non-insertable
devices.
Broadband Loads
The broadband loads are metrology-grade, 50Ω terminations that have been
optimized for performance up to 50 GHz. The rugged internal structure
provides for highly repeatable connections. A distributed resistive element on
sapphire provides excellent stability and return loss.

General Information
Calibration Kit Overview
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. 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 180 degrees at all frequencies.
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
— entered from the front panel
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
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 6-2 on page 2 for
ordering information.

General Information
Precision Slotless Connectors
Precision Slotless Connectors
The female 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.

General Information
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 sex of
cable connectors and adapters is referred to in terms of the center conductor.
For example, a connector or device designated as 2.4 mm –f– has a 2.4 mm
female center conductor.
A connector gage is referred to in terms of the connector that it measures. For
instance, a male connector gage has a female center conductor on the gage so
that it can measure male devices.
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 techniques 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 3), or from bad connection techniques,
can also damage these devices.
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,

When to Calibrate
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.

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. Keysight
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 3-7 explains how to use gages to determine if
the kit devices have maintained their mechanical integrity. Refer to Table 2-2
on page 3 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
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 ΜΩ 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 Table 6-2 on page 6-2 for information on ordering
supplies for ESD protection.

Use, Maintenance, and Care of the Devices
Inspecting Connectors
Inspecting Connectors
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 Figure 2-1 on page 2-2. 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.

Use, Maintenance, and Care of the Devices
Inspecting Connectors
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.
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.
This is particularly important when mating nonprecision to precision
devices.
The female 2.4 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 female 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.

Cleaning Connectors
Cleaning Connectors
Clean connectors are essential for ensuring the integrity of RF and microwave
coaxial connections.
1. Use Compressed Air or Nitrogen
Always use protective eyewear when using compressed air or
nitrogen.
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.
2. Clean the Connector Threads
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

Gaging Connectors
Gaging Connectors
The gages available from Keysight Technologies are intended for preventive
maintenance and troubleshooting purposes only. See Table 6-2 on page 6-2
for part number information. 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.
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 2-3 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 on page 2-3 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 in Table 2-2 on page 2-3.
The observed pin depth limits in Table 2-2 on page 2-3 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 2-2. Refer to “Kit
Contents” on page 1-1 for more information on the design of the calibration
devices in the kit.
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 2-3 to evaluate the condition of device
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 2.4 mm Connectors
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 6-2 on page 6-2
for gage part numbers.
2. Inspect and clean the gage, gage master, and device to be gaged. Refer to
“Inspecting Connectors” 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 3-13 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 3-13 for additional information.
c. Gently tap the barrel of the gage with your finger to settle the gage
read ing.
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 2-3.

Making Connections
Making 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 3-1 for ESD precautions.
2. Visually inspect the connectors. Refer to “Inspecting Connectors” on
page 3-3.
3. If necessary, clean the connectors. Refer to “Cleaning Connectors” on
page 3-5.
4. Use a connector gage to verify that all center conductors are within the
observed pin depth values in Table 2-2 on page 2-3. Refer to “Gaging
Connectors” on page 3-7.
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.
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 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.

Making Connections
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 6-1 for replacement part number and ordering information.
Table 3-1 Torque Wrench Information
Connector TypeTorque SettingTorque Tolerance
2.4 mm90 N-cm (8 in-lb)±9.0 N-cm (±0.8 in-lb)
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.

3-
Use, Maintenance, and Care of the Devices
Handling and Storage
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.
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. Do not tighten
the connection further.
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.
Do not turn the device body. Only turn the connector nut. Damage to the
center conductor can occur if the device body is twisted.
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.
Handling and Storage
— Install the protective end caps and store the calibration devices in the
foam-lined storage case when not in use.
3-14 Keysight 85056D and 85563A/85564A User’s and Service Guide
Use, Maintenance, and Care of the Devices
Handling and Storage
— 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.

4Performance Verification
The performance of your calibration kit can only be verified by returning the kit
to Keysight 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 Keysight Verifies the Devices in Your Kit
Keysight 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, Keysight 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 Keysight 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 Keysight Technologies.

Performance Verification
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
A list of NIST traceable numbers may be purchased upon request to be
included in the calibration report.
Keysight Technologies offers a Standard calibration for the recertification of
the kit. For more information, contact Keysight Technologies. See “Contacting
Keysight” 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.
The recertification interval should begin on the date the kit is first used
after the recertification date.
Where to Send a Kit for Recertification
Contact Keysight Technologies for information on where to send your kit for
recertification. See “Contacting Keysight” on page 5-5. Refer to “Returning a
Kit or Device to Keysight” on page 5-4 for details on sending your kit.
