General Information

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

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.

Ta bl e 1-2 Clarifying the Terminology of Connectors: Examples

Terminology Meaning

Short –f–

Short (f) Male short (male center conductor) to be connected to female port

A connector gage is referred to in terms of the connector that it measures. For instance, a male connector gage has a female connector on the gage so that it can measure male devices.

Female short (female center conductor)

Preventive Maintenance

The best techniques for maintaining the integrity of the devices in your kit include:

• routine visual inspection

• cleaning

• proper connection techniques

All of these 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 limit (see

Table 2-2 on page 2-4) 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

85038A/F/M 1-5

General Information

When to Calibrate

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.

Mechanical Characteristics

Mechanical characteristics such as pin depth are not performance specifications. They are, however, important supplemental characteristics related to electrical performance.

Pin Depth

Pin depth is the distance the center conductor mating plane differs from being flush with the outer conductor mating plane. See

Ta b l e 2 -2 .

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.

Recession is the condition in which the center conductor is set back from the outer conductor mating plane.

3 Use, Maintenance, and Care of the Devices

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 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.

Refer to Chapter 6 , “Replaceable Parts,” for part numbers and instructions for ordering ESD protection devices.

Figure 3-1 ESD Protection Setup

3-2 85038A/F/M

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. See 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.

Figure 2-1 on page 2-3. Look especially for deep scratches or dents, and for dirt and metal

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.

85038A/F/M 3-3

Use, Maintenance, and Care of the Devices

Cleaning Connectors

Inspect Female Connectors

Pay special attention to the contact fingers in the female center conductor. 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.

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. 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

2. Clean the Connector Threads

WARNING Keep isopropyl alcohol away from heat, sparks, and flame. Store in a tightly closed

“Electrostatic Discharge” on page 3-2 for additional information.

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

6-2 on page 6-5 for part numbers for cleaning swabs.

a. Apply a small amount of isopropyl alcohol to a lint-free cleaning swab.

b. Clean the connector threads.

c. Let the alcohol evaporate, then blow the threads dry with a gentle stream of clean, low-pressure

compressed air or nitrogen. Always completely dry a connector before you reassemble or use it.

3. Clean the Mating Plane Surfaces

a. Apply a small amount of isopropyl alcohol to a lint-free cleaning swab.

b. Clean the center and outer conductor mating plane surfaces. Refer to Figure 2-1 on page 2-3. When

cleaning a female connector, avoid snagging the swab on the center conductor contact fingers by using short strokes.

c. Let the alcohol evaporate, then blow the connector dry with a gentle stream of clean, low-pressure

compressed air or nitrogen. Always completely dry a connector before you reassemble or use it.

Ta bl e

4. Reinspect

Inspect the connector again to make sure that no particles or residue are present.

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

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.

“Electrostatic Discharge” on page 3-2 for ESD precautions.

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

Use, Maintenance, and Care of the Devices

Connections

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. Tabl e 3 -1 provides information about the torque wrench recommended for use with these calibration kits. A torque wrench is included in the 85038A calibration kit but not in the 85038F/M calibration kits. Refer to information.

Ta bl e 3-1 Torque Wrench Information

Connector Type Torque Setting Tor q u e Tol e ran c e

7-16 226 N-cm (20 in-lb) 22.6 N-cm (2.0 in-lb)

Chapter 6 for part number and ordering

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 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.

3-6 85038A/F/M

Use, Maintenance, and Care of the Devices

Connections

Figure 3-2 Wrench Positions

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 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.

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.

85038A/F/M 3-7

Use, Maintenance, and Care of the Devices

Handling and Storage

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.

How to Separate a Connection

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

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.

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.

Handling and Storage

• Install the protective end caps and store the calibration devices in the foam-lined storage case when not in use.

• Never store connectors loose in a box, or in a desk or bench drawer. This is the most common cause of connector damage during storage.

• Keep connectors clean.

• Do not touch mating plane surfaces. Natural skin oils and microscopic particles of dirt are easily transferred to a connector interface and are very difficult to remove.

• Do not set connectors contact-end down on a hard surface. The plating and the mating plane surfaces can be damaged if the interface comes in contact with any hard surface.

4 Performance Verification

Performance Verification

Introduction

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 your kit is traceable to NIST through Keysight Technologies.

4-2 85038A/F/M

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.

Keysight Technologies offers a Standard calibration for the recertification of your kit. For more information, contact Keysight Technologies. For contact information, see

How Often to Recertify

“Contacting Keysight” on page 5-5.

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 Keysight Technologies for information on where to send your kit for recertification. For contact information, see “Contacting Keysight” on page 5-5.

When you return the kit, complete and attach a service tag. Refer to "Returning a Kit or Device to

Keysight," on page 5-4 for details.
