General Information
Precision Slotless Connectors
Precision Slotless Connectors
The female 3.5 mm connectors in this verification 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 Keysight Technologies 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 50Ω
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 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.
A connector gage is referred to in terms of the connector that it measures. For
instance, a male connector gage has a female connector on the gage so that it
can measure male devices.
Preventive Maintenance
The best techniques for maintaining the integrity of the devices in this kit
include:
— routine visual inspection
—cleaning
—proper gaging
— proper connection techniques
All of these are described in Chapter 3. Failure to detect and remove dirt or
metallic particles on a mating plane surface can degrade repeatability and
accuracy and can damage any connector mated to it. Improper connections,
resulting from pin depth values being out of specification (see Table 2-2 on
page 4), or from bad connection techniques, can also damage these devices.

Mechanical Characteristics
Mechanical Characteristics
Mechanical characteristics such as center conductor protrusion and pin depth
are not warranted performance specifications. They are, however, important
supplemental characteristics related to electrical performance. Keysight
Technologies verifies the mechanical characteristics of the devices in this kit
with special gaging processes and electrical testing. This ensures that the
device connectors do not exhibit any improper pin depth when the kit leaves
the factory.
“Gaging Connectors” on page 7 explains how to use gages to determine if the
kit devices have maintained their mechanical integrity. Refer to Table 2-2 on
page 4 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.

3 Use, Maintenance, and Care of the Devices
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.
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.

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.
Devices with damaged connectors should be immediately discarded or
clearly marked and set aside for repair. A damaged device will in turn
damage any good connector to which it is attached. Determine the cause
of the damage before connecting a new, undamaged connector in the
same configuration.
In some cases, magnification is necessary to see damage to a connector; a
magnifying device with a magnification of ≥10× 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 or 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 4. 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.
85053B 3-3
3-
Use, Maintenance, and Care of the Devices
Visual Inspection
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.
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 connectors in this calibration kit are metrology-grade, precision
slotless connectors (PSC). Precision slotless female 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
1. Use Compressed Air or Nitrogen
Clean connectors are essential for ensuring the integrity of RF and
microwave coaxial connections.
Always use protective eyewear when using compressed air or
nitrogen.
Use compressed air (or nitrogen) to loosen particles on the connector
mating plane surfaces.
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” on page 1 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
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 6-3 on page 5 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.

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 4. 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

Use, Maintenance, and Care of the Devices
Gaging Connectors
Gaging Connectors
The gages available from Keysight 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.
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 then, 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.
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. This serves as a good
troubleshooting tool when you suspect damage may have occurred to the
device.
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 4 and with previously recorded values
to evaluate the condition of device connectors.
— 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 verification device is used by someone else or on another system or
piece of equipment.

Gaging Procedures
Gaging 3.5 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 6-3 on page 5
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

Gaging the Airline
The airlines in this kit are measured and matched for length at the factory using
special fixtures and gages. Because the gages supplied in the calibration kits
do not have the accuracy of the factory gages, use the following procedure for
very general results only. Perform this procedure whenever you suspect that a
center conductor has been switched with another airline or that a device has
been damaged.
Always hold a connector gage by the gage barrel, below the dial indicator.
This gives the best stability, and improves measurement accuracy.
1. Select a male connector gage and male short for this procedure. Refer to
Table 6-3 on page 5 for part numbers.
2. Inspect and clean the mating surfaces and connector threads of the short,
airline, and gage. Refer to “Visual Inspection” and “Cleaning Connectors”
earlier in 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 short, connect the gage to the short 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 recommended for use with this kit to tighten
the connecting nut to the specified torque. Refer to “Final
Connection Using a Torque Wrench” on page 17 for additional
information.
c. As you watch the gage pointer, gently tap the barrel of the gage to

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 1 for ESD precautions.
2. Visually inspect the connectors. Refer to “Visual Inspection” on page 3.
3. If necessary, clean the connectors. Refer to “Cleaning Connectors” on
page 5.
4. Use a connector gage to verify that all center conductors are within the
pin depth values listed in Table 2-2 on page 4. Refer to “Gaging
Connectors” on page 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. Turn only the connector nut. Damage to the
center conductor can occur if the device body is rotated.
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 not included in the calibration kit. Refer to Table 6-3 on
page 5 for part number and ordering information.
Table 3-1 Torque Wrench Information
Connector Type Torque Setting Torque Tolerance
3.5 mm 90 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 3-6. 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 3-6 Wrench Positions
2. Hold the torque wrench lightly, at the end of the handle only (beyond the
groove). See Figure 3-7.

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.
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.
4. Tighten the connection just to the torque wrench break point. The wrench
handle gives way at its internal pivot point. See Figure 3-7. Do not tighten
the connection further.
Connecting the Airline
Before making any connections to the test set, be sure that bias power to
the test set is off, and take care to avoid electrostatic discharge. Refer to
“Electrostatic Discharge” on page 1.
Wear gloves while performing the following procedure. You will be
touching the exposed center conductor of the airline. It is important that
you do not transfer oil and dirt from your fingers to this center conductors.
Refer to “Handling and Storage” on page 21.
Before making the connection, refer to “Preliminary Connection” on page 16.
Cables with the appropriate adapters on the ends should be connected to
PORT 1 and PORT 2 of the network analyzer.
1. Remove the center conductor from its plastic case. Make sure you select
the correct center conductor for the airline you are connecting. Refer to
Figure 2-3 and Figure 2-4 on page 6 for illustrations of both center

— 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.

4 Performance Verification
Introduction
The performance of your verification 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 device is electrically tested on this system. For the initial (before
sale) testing of the 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.

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 4.
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 4. Refer to “Returning a Kit
or Device to Keysight” on page 4 for details on sending your kit.

Replacing the Verification Data
The verification data contains unique performance data that applies to the
individual verification devices. No two devices have the same performance
data. It is not a trivial matter to replace lost or damaged data, so it is important
to make one or more backup copies.
If your verification data is lost or damaged, and you have no backup copies,
take one of the following actions:
— If recertification is not required in the near future.
Contact Keysight for replacement verification data - refer to “Contacting
Keysight” on page 4. Please specify the information in the table below.
— If recertification will be required in the near future.
Keysight recommends that you have the verification kit recertified early.
New verification data will be generated during the recertification process.
Refer to “Recertification” on page 2.

Copying Replacement Device Verification Data to the Original Verification Data Media
Copying Replacement Device Verification Data to the Original
Verification Data Media
IMPORTANT! The information in the following two processes applies only
to writable USB drives. If the USB drive shipped with your verification kit or
replacement device has either the Keysight or Keysight logo on it, it is
read-only, and the following two processes do not apply. If this is the case,
simply use the USB drive that was shipped with your replacement device
when you connect that device during the system verification process.
This section describes how to copy the new replacement device verification
data from the USB drive provided with the device, to the verification data
media (floppy disk or USB) included with the original verification kit. Please be
aware that once you write over the “old” data, the data cannot be recovered.
Therefore, it is highly recommended that you follow the procedure below in
“Old Verification Device Data – Backup Process” to make a backup copy of the
“old” verification data BEFORE you perform the “New Verification Device Data
-Transfer Process” procedure. Be sure to keep the new USB drive. It will be
your backup copy of the new replacement device verification data.
This procedure assumes you have access to a PC or a PNA to perform
these tasks.
Old Verification Device Data – Backup Process
1. Insert the old verification device data media (floppy disk or USB) into your
computer or PNA and view the contents with Windows Explorer.
2. Copy all of the files to the clipboard.
3. Remove the old verification device data media (floppy disk or USB) from
your computer or PNA.
4. Insert the new USB drive into your computer or PNA and view the contents
with Windows Explorer.
5. Create a new directory on the new USB drive and name it using the format
Model_Serial_YYYYMMDD. Use your kit’s model number, serial number,
and the current date. Example: 85055A_2815A01234_20120827.
6. Open the new directory you created in the previous step and paste the
files from the clipboard.
All of the files (nine files: one .txt file, four .dat files, and four .unc files) you
copied from the old verification device data media should be present. You
now have a complete backup of the old verification device data on the new
USB drive.

Copying Replacement Device Verification Data to the Original Verification Data Media
New Verification Device Data – Transfer Process
1. If not already done, insert the new USB drive into your computer or PNA
and view the contents with Windows Explorer.
2. Copy all of the files with .DAT and .UNC file extensions to the clipboard,
except the old files you copied in the new directory.
3. Note the dates of the files you just copied to the clipboard.
4. Remove the new USB drive from your computer or PNA.
5. Insert the old verification device data media (floppy disk or USB) into your
computer or PNA and view the contents with Windows Explorer.
6. Paste the files from the clipboard into the top-level directory.
7. When prompted if you want to write-over existing files, click YES.
The new .DAT and .UNC files should show newer dates relative to your
original files.
8. Select the “kitparts.txt” file and open it with Notepad or Wordpad.
9. Locate the line for the verification device you just replaced (device 1, 2, 3
or 4).
10. Change the serial number at the end of the line to the serial number of
the new device you received in the replacement kit.
11. Save and close the kitparts.txt file.
12. Remove the old verification device data media (floppy disk or USB) from
your computer or PNA.
Your new replacement device is now ready to use with your PNA.
