General Information

Calibration Kit Overview

The Agilent 85036B and 85036E type-N calibration kits are used to calibrate Agilent

network analyzers up to 3 GHz for measurements of components with 75Ω type-N

connectors.

Kit Contents

Use the Contents List in the shipping container to verify the completeness of your

shipment. Although this list is the most accurate, you can also use the illustrations in

Chapter 7 to verify the items in your shipment. If your shipment is not complete, contact

Agilent Technologies - refer to “Contacting Agilent” on page 5-4.

Refer to Table 6-1 and Table 6-2 for a list of kit contents part numbers.

Broadband Loads

The broadband loads are instrument-grade, 75Ω terminations that have been optimized for

performance up to 3 GHz. The rugged internal structure provides for highly repeatable

connections. A distributed resistive element on sapphire provides excellent stability and

return loss.

Opens and Shorts

The opens and shorts are built from parts that are machined to the current state-of the-art

precision machining.

The short’s inner conductors have a one-piece construction, common with the shorting

plane. This construction provides for extremely repeatable connections.

The female open has a separate-piece inner conductor that is made from a

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. Some of the opens and shorts have offsets. The

lengths of these offsets are designed so that the difference in phase of their reflection

coefficients is approximately 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. The adapters utilize a dual-beaded connector structure to

ensure stable, repeatable connections. The beads are designed to minimize return loss and

are separated far enough so that interaction between the beads is minimized.

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. Refer to your

network analyzer user’s guide for instructions on selecting the calibration kit and

“Contacting Agilent” on page 5-4.

Agilent 85036B kits with serial prefix 3103A and below

These calibration kits had a center conductor extender with a smaller body. Therefore, a

different procedure was used for connecting the female open. If you’re using one of the

smaller extenders, replace the steps in “Connecting and Disconnecting the Two-Piece

Female Open (85036B)” on page 3-9 of this manual with the steps below.

1. Mate the center conductor extender to the male pin of the test port.

2. Connect the open body to the test port by carefully guiding it over the extender.

3. To disconnect the open, carefully remove the open body first.

The part numbers in this manual are the recommended replacement parts for these kits

(including the center conductor extender).

General Information

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.

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 the above are described in Chapter 3 , “Use, Maintenance, and Care of the Devices.”

Failure to detect and remove dirt or metallic particles on a mating plane surface can

degrade repeatability and accuracy and can damage any connector mated to it. Improper

connections, resulting from pin depth values being out of the limits (see Table 2-2 on page

2-3), or from bad connections, can also damage these devices.

General Information

When to Calibrate

A network analyzer calibration remains valid as long as the changes in the systematic

error are insignificant. This means that changes to the uncorrected leakages (directivity

and isolation), mismatches (source match and load match), and frequency response of the

system are small (<10%) relative to accuracy specifications.

Change in the environment (especially temperature) between calibration and

measurement is the major cause in calibration accuracy degradation. The major effect is a

change in the physical length of external and internal cables. Other important causes are

dirty and damaged test port connectors and calibration standards. If the connectors

become dirty or damaged, measurement repeatability and accuracy is affected.

Fortunately, it is relatively easy to evaluate the general validity of the calibration. To test

repeatability, remeasure one of the calibration standards. If you can not obtain repeatable

measurements from your calibration standards, maintenance needs to be performed on the

test port connectors, cables and calibration standards. Also, maintain at least one sample

of the device under test or some known device as your reference device. A verification kit

may be used for this purpose. After calibration, measure the reference device and note its

responses. Periodically remeasure the device and note any changes in its corrected

response which can be attributed to the test system. With experience you will be able to see

changes in the reference responses that indicate a need to perform the measurement

calibration again.

Environmental Requirements

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 specified in

Table 2-1.

IMPORTANT

Avoid unnecessary handling of the devices during calibration because your

fingers are a heat source.

Use, Maintenance, and Care of the Devices

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 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.

Refer to Chapter 6 , “Replaceable Parts,” for part numbers and instructions for ordering

ESD protective devices.

85036B/E 3-3

Use, Maintenance, and Care of the Devices

Visual Inspection

Visual inspection and, if necessary, cleaning should be done every time a connection is

made. Metal particles from the connector threads may fall into the connector when it is

disconnected. One connection made with a dirty or damaged connector can damage both

connectors beyond repair.

Magnification is helpful when inspecting connectors, but it is not required and may

actually be misleading. Defects and damage that cannot be seen without magnification

generally have no effect on electrical or mechanical performance. Magnification is of great

use in analyzing the nature and cause of damage and in cleaning connectors, but it is not

required for inspection.

Look for Obvious Defects and Damage First

Examine the connectors first for obvious defects and damage: badly worn plating on the

connector interface, deformed threads, or bent, broken, or misaligned center conductors.

Connector nuts should move smoothly and be free of burrs, loose metal particles, and

rough spots.

What Causes Connector Wear?

Connector wear is caused by connecting and disconnecting the devices. The more use a

connector gets, the faster it wears and degrades. The wear is greatly accelerated when

connectors are not kept clean, or are connected incorrectly.

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. 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.

Use, Maintenance, and Care of the Devices

Cleaning Connectors

Clean connectors are essential for ensuring the integrity of RF and microwave coaxial

connections.

1. Use Compressed Air or Nitrogen

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”

earlier in this chapter 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 Table 6-3 on page 6-5 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.

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

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. 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.

3-6 85036B/E

Use, Maintenance, and Care of the Devices

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.

CAUTION

Never mate a 50 ohm connector with a 75 ohm connector. The larger center

pin of a male 50 ohm connector will destroy the contact fingers of a female

75 ohm connector.

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. Carefully align the connectors. The male connector center pin must slip concentrically

into the contact finger of the female connector.

5. Push the connectors straight together.

CAUTION

Do not turn the device body. Only turn the connector nut. Damage to the

center conductor can occur if the device body is twisted.

Do not twist or screw the connectors together. As the center conductors mate, there is

usually a slight resistance.

6. 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.

7. 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

1. Use a torque wrench to make a final connection. Table 3-1 provides information about

the torque wrench recommended for use with this calibration kit. A torque wrench is

not included in the calibration kit. Refer to Chapter 6 for part number and ordering

information.

85036B/E 3-7

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.

2. 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).

In all situations, however, it is recommended that you use an open-end wrench to keep

the body of the device from turning. Refer to Chapter 6 “Replaceable Parts” for part

number and ordering information.

3. Position both wrenches within 90 degrees of each other before applying force. See

Figure 3-2. 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.

Use, Maintenance, and Care of the Devices

Connections

4. Hold the torque wrench lightly, at the end of the handle only (beyond the groove). See

Figure 3-3.

Figure 3-3 Using the Torque Wrench

5. Apply downward force perpendicular to the wrench handle. See Figure 3-3. 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.

6. Tighten the connection just to the torque wrench break point. The wrench handle gives

way at its internal pivot point. See Figure 3-3. 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.

Do not pivot the wrench handle on your thumb or other fingers, otherwise you apply an

unknown amount of torque to the connection when the wrench reaches its break point.

Do not twist the head of the wrench relative to the outer conductor mating plane. If you

do, you apply more than the recommended torque.

Use, Maintenance, and Care of the Devices

Connections

Connecting and Disconnecting the Two-Piece Female Open (85036B)

The female open standard in the 85036B calibration kit is composed of two parts: the open

body (outer conductor) and the center conductor extender. Refer to Figure 3-4.

Figure 3-4 Connecting the Two-Piece Female Open

To connect the female open:

1. Connect the open body to the male test port.

2. Insert the center conductor extender into the hole at the end of the body and push

gently until the center conductors mate.

To disconnect the female open:

1. Remove the center conductor extender by pulling gently outwards without twisting,

rocking, or bending the extender or the body.

2. Disconnect the body from the test port.

How to Separate a Connection

To avoid lateral (bending) force on the connector mating plane surfaces, always support the

devices and connections.

CAUTION

Turn the connector nut, not the device body. Major 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 connector nut.

3. Complete the separation by hand, turning only the connector nut.

4. Pull the connectors straight apart without twisting, rocking, or bending either of the

connectors.

3-10 85036B/E

Use, Maintenance, and Care of the Devices

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, 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

4-2 85036B/E

Performance Verification

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 This 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 NIST (National Institute of Standards

and Technology). 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 this kit is

traceable to NIST through Agilent Technologies.

85036B/E 4-3

Performance Verification

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 this kit. For

more information, contact Agilent Technologies. See “Contacting Agilent” 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.

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.
