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 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 2-4), or from bad connection techniques, can also damage these devices.

Temperature—What To Watch Out For
Due to the small dimensions of the devices, electrical characteristics will change with temperature. Therefore, the operating temperature is a critical factor in their performance, and must be stable before use.
IMPORTANT Avoid unnecessary handling of the devices during use because your fingers are a heat
source.

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. Agilent 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 3-7 explains how to use gages to determine if the kit devices have maintained
their mechanical integrity. Refer to Table 2-2, “Connector Pin Depths,” for allowable recession.
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 conditions:
• 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.

Using these mechanical dimensions, you can calculate the expected electrical performance with the equations in the following publications:
• Nelson, Robert E., and Marlene R. Coryell, “Electrical Parameters of Precision, Coaxial, Air-Dielectric
Transmission Lines”, U.S. National Bureau of Standards Monograph No. 96.
• Somlo, P.I., “The Computation of Coaxial Line Step Capacitances”, IEEE Transactions on Microwave
Theory and Techniques, Volume MTT-15, No. 1, January, 1967.
The measurement method in these publications provides a general idea of the expected device characteristic impedance. Variations in connector interfaces can have a large effect on your actual electrical measurements.

Use, Maintenance, and Care of the Devices
Electrostatic Discharge
Electrostatic Discharge
Protection against ESD (electrostatic discharge) 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 (DUTs), 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 M 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. For parts numbers of
ESD protection supplies, refer to Ta bl e 6 -3

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.
CAUTION 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 10is 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 PNA 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.

Use, Maintenance, and Care of the Devices
Visual Inspection
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 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 approximately 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.
WARNING 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 3-2 for additional information.
2. Clean the Connector Threads
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 Ta bl e 6 -3
on page 6-5 for part numbers for isopropyl alcohol and 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.

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.
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.
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.
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.
• 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.
• Initially, after every 100 connections, and after that, as often as experience indicates.

Gaging Procedures
Gaging 2.4 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. The gages are intended for performing 2.4 mm pin depth measurements. Refer to Table 6-3 on page 6-5 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
Torque Wrench” on page 3-14 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 3-14 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 specifications listed in Table 2-2 on page 2-4.
f. Without turning the gage or the device, remove the device from the gage.

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.
NOTE Always hold a connector gage by the gage barrel, below the dial indicator. This gives the best
stability, and improves measurement accuracy.
1. Select a male connector gage and male short for this procedure. Refer to Table 6-3 on page 6-5 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 3-14 for additional information.
c. As you watch the gage pointer, gently tap the barrel of the gage to settle the reading.
d. The gage pointer should line up exactly with the zero mark on the gage. If not, loosen the dial lock
screw on the gage and rotate the gage dial so that the pointer is aligned with the zero mark. Tighten
the dial lock screw.

Use, Maintenance, and Care of the Devices
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 3-5.
4. Use a connector gage to verify that all center conductors are within the pin depth values listed in Ta b l e
2-2 on page 2-4. 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.
CAUTION 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. Ta b l e 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 6-5 for part number and ordering information.

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.
Figure 3-7 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.

Connections
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.
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
CAUTION 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 3-2.
CAUTION 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 3-18.
Before making the connection, refer to “Preliminary Connection” on page 3-14.
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 2-6 for illustrations of both center conductors.
2. Remove the protective end cap from the female end (the end without the connecting nut) of the airline. Leave the protective end cap on the male end of the airline to prevent the center conductor from falling out of the outer conductor.
3. Insert the female end of the center conductor into the outer conductor so that the female end of the center conductor is toward the female end of the outer conductor (the end without the connector nut).

Handling and Storage
• Do install the protective end caps and store the devices in the foam-lined storage case when not in use.
• Do keep connectors and airlines clean.
• Do not store connectors and airlines loose in a box, or in a desk or bench drawer. This is the most
common cause of connector damage during storage.
• Do not touch mating plane surfaces. Natural skin oils and microscopic particles of dirt are easily
transferred to a connector interface and are very difficult to remove.
• Do not set connectors contact-end down on a hard surface. The plating and the mating plane surfaces
can be damaged if the interface comes in contact with any hard surface.

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

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
NOTE A list of NIST traceable numbers may be purchased upon request to be included in the
calibration report.
Agilent Technologies offers a Standard calibration for the recertification of the kit. For more information, contact Agilent Technologies. Refer to “Contacting Agilent” on page 5-7.
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
Contact Agilent Technologies for information on where to send your kit for recertification. Refer to
