PREVENTWE MAINTENANCE

The best techniques for maintaining the integrity of the devices in this kit include routine visual inspection and cleaning, and proper gaging and connection techniques. Failure to detect and remove dirt or metallic particles on a connector 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

the observed lim-

its (see Table 2-2) or from using poor connection techniques can also damage these devices. Visual inspection, cleaning and connection techniques, and proper gaging for pin depth are all described

in Chapter 4, “Preparation for Use - Gaging and Making Connections.”

The definitions explained here help to clarify the terms used in the remainder of this chapter. These definitions refer to the HP 85062A 3.5 mm Electronic Calibration Kit only and are not necessarily valid definitions for other HP products.

Operating Temperature Range.

This is the temperature range over which the calibration standards main-

tain performance to their specifications.

Accuracy-Enhanced Temperature Range.

This is the allowable network analyzer ambient temperature drift during measurement calibration and during measurements when the network analyzer correction is turned on. It is also the range over which the network analyzer maintains its specified performance while correction is turned on.

this temperature range is exceeded, the accuracy-enhanced performance of the

network analyzer will be degraded.

Measurement Calibration.

This is the calibration performed to determine the corrections necessary for

accuracy-enhanced (correction on) measurements.

Limits

Temperature of the calibration modules is important because device dimensions (and therefore electrical characteristics) change with temperature. The temperature of the calibration devices and all connectors must be stable before use and within the operating limits shown above.

A measurement calibration of the network analyzer can be made at any temperature within the operating temperature range

the calibration kit. The measurement calibration temperature of the

network

analyzer must be maintained within the error corrected temperature range of the network analyzer. The error corrected operating temperature range for most HP network analyzers is the initial measurement calibration temperature &l “C (21.8 “F). See the appropriate network analyzer User’s Manual.

Measurement calibration, performance verification, and actual device measurements must be made within the error corrected operating temperature range specification of the network analyzer. Part

the error corrected operating temperature range can fall outside of the calibration temperature window. For example, if

measurement calibration is performed at +20 “C (+68 “F), verification and measurements must be made

between t-19 “C (+66.2 OF) and +21 “C (+69.8 “F). Also,

the network analyzer ambient operating temperature drift exceeds the allowable error corrected temperature range, a new measurement calibration must be performed to assure optimum accuracy.

Remember that your fingers are a heat source, so avoid handling the devices unnecessarily during calibration.

Mechanical characteristics such as center conductor protrusion and pm depths are not performance specifications. They are, however, important supplemental characteristics related to electrical performance. Hewlett-Packard 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 center conductor protrusion and have proper pin depth when the kit leaves the factory.

Note that center conductor protrusion or recession is referenced to the connector mating surface.

THE CALIBRATION DEVICES AND

THEIR USE

The HP 85062A 3.5 mm Electronic Calibration Kit contains a high band (1 to 26.5 GHz) electronic calibration module, Option 001 adds a low band (45 MHz to 2 GHz) electronic calibration module. Other options are described in Chapter 1.

The following briefly describes the design, construction, and functionality of an electronic calibration module.

Design, Construction,

Electronic calibration is achieved using a two part system consisting

and

Functionality

of an HP

8506OC Electronic Calibration Control Unit and various two-port electronic calibration modules. The control unit houses a computer with built-in firmware and controls the entire calibration process. The calibration modules are solid-state devices with programmable repeatable impedance states. These modules are characterized at Hewlett-

Packard and are used to transfer the factory calibration accuracy to the customer. The microwave circuitry in the module uses semiconductor PIN diode switches which shunt the transmis-

sion lines to ground. The number ments. A multitude

reflection coefficients are generated by applying various combinations

diodes, and their location, vary depending upon the frequency require-

the shuntsWithout shunts, the network acts as a low-loss transmission line. High isolation between the ports is obtained by driving several of the PIN diode shunts simultaneously. Control logic within the module is programmed to drive the PIN diodes to their various states.

The factory measured S-parameter data

each of the various impedance states is stored inside

the module. This factory data is compared to the measured data, collected during the calibration process, and error terms are calculated.

CALIBRATION CONSTANTS

The HP 85062A Electronic Calibration Kit is unlike our standard mechanical calibration kits. There are no calibration constants to be loaded into the network analyzer. All of the calibration data for each individual electronic calibration module is stored within the module, and is traceable to NIST (National Insti-

tute of Standards and Technology). This calibration data is read by the HP 8506OC Electronic Calibration

Control Unit each time a calibration is performed.

PERFORMING CALIBRATIONS

The calibration type and procedure to be used depends on the type and accuracy of measurement required for the device-under-test. The operating, programming, and service manual for the HP 8506OC Electronic

Calibration Control Unit provides information regarding the available calibration types, the best applica-

tion for each type, and describes the calibration procedures in detail. For information regarding specific network analyzers, refer to the appropriate network analyzer user’s

manual or Hewlett-Packard application notes.

CHANGING THE CALIBRATION

DATA

The calibration data stored in each electronic calibration module is unique to that module and can only be changed when the module is recertified or repaired. This recertification or repair can only be performed at Hewlett-Packard or at Hewlett-Packard authorized service centers.

OPERATING PRECAUTIONS

Preparation For Use - Gaging and Making Connections

There are several precautions that must be observed to protect the devices in this kit and the instruments

being used.

Handling and

Storage

Handle and store these calibration devices with great care; their continued performance and accuracy de-

pend on maintaining very precise mechanical tolerances of the connectors. When the calibration modules are not in use, replace their protective end caps and store them in the foam

lined storage case. The storage case lid is detachable so that the case can be stored in a shallow drawer.

Electrostatic Discharge

The human body almost always has some static charge. You are usually not aware of this charge because

CAUTION

the

human threshold for the perception of static discharge shock is approximately 3,000 volts. ESD as low as 60 volts can destroy sensitive microcircuits. Always wear a grounding wrist strap connected to a conductive bench mat when working near this and other sensitive equipment.

When you clean or inspect connectors attached to any static sensitive circuits, either on the calibration module or on any instruments, it is essential to protect against electrostatic discharge (ESD). Static electricity builds up on the body and can easily damage sensitive internal circuit elements when discharged by contact with the

strap attached to it.

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 briefly to discharge static from your body.

Discharge static electricity from a device before connecting it: touch the device briefly (through a resistor

of at

least 1 megohm) to either the outer shell

another exposed

ground. This discharges static electricity and protects test equipment circuitry.

“Replaceable Parts”, for information about ordering supplies for ESD protection.

Preparation For Use - Gaging and Making Connections

4-l

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.

In some cases, magnification is necessary to see damage on a connector. The use of a microscope with a magnification of 10x or more is recommended to detect this type

damage. Not all defects that are visible under magnification will affect the electrical performance of the connector. Use the following guidelines when evaluating the integrity of a connector.

Obvious Defects or Damage

Examine the connectors first for obvious defects or damage: badly worn plating, deformed threads or bent, broken, or misaligned center conductors. Connector nuts should move smoothly and be free

burrs, loose

metal particles, and rough spots. Any connector that has obvious defects should be discarded or repaired before continuing.

Mating Plane

Flat contact

nection.

Look

Surfaces

between the connectors at all points on their mating plane surfaces is required for a good con-

especially for deep scratches

dents, and for dirt and metal particles on the connector mat-

ing plane surfaces. Also, look for bent or rounded edges on the mating plane surfaces of the center and outer conductors and

for signs of damage due to excessive or uneven wear or misalignment. Light burnishing

marks distributed more or less uniformly

the mating plane surface is normal, and is evident as light scratches

over

the mating plane surfaces. Other small defects and cosmetic

shallow circular

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. Damaged connectors should be discarded or sent for repair. Try to determine the cause of damage before connecting a new, undamaged connector in the same configuration.

Connector Wear

Connector wear eventually degrades performance. The more use a connector gets, the faster it wears and degrades. This is especially true with electrically characterized devices such as ECal modules. The wear is greatly accelerated when connectors are not kept clean. Calibration devices should have a long life if their use is on the order of a few times per week. 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. Replace all worn connectors.

To keep your main supply of alcohol free from contamination, pour a small amount into a clean container and use that as your cleaning supply. Safely discard any remaining alcohol in the small container and clean the container.

CAUTION

GENERAL CLEANING PROCEDURES

Warning

wed

If you must use a solvent, use only isopropyl alcohol. Use the least amount of alcohol possible, and avoid wetting any plastic parts in the connectors.

Always use protective eyewear when using compressed air or nitrogen. This procedure

assumes you have taken the necessary ESD precautions.

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 oilvapor 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 a very low velocity; 60 psi or less. High velocity air can cause electrostatic effects when directed into a connector.

For dirt or stubborn contaminants on a connector that you cannot remove with compressed air or nitrogen, try a cleaning swab or lint-free cleaning cloth moistened with isopropyl alcohol:

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

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

Apply a small amount of isopropyl alcohol to a new

the connector has a center conductor, use very short horizontal or vertical strokes (across the connector), and the least pressure possible, especially when cleaning a female connector (to avoid snagging the swab on the center conductor contact fingers). An illuminated magnifying glass helps.

GAGING DEVICES IN THIS Gage

Intent

KIT

Gages are intended for preventive maintenance and troubleshooting purposes only. They are effective in detecting center conductor protrusion or excessive recession and preventing connector damage on DUT’s, test accessories, and the calibration kit devices. Do not use gages for precise pin depth measurements.

While performing pin depth measurements, use different orientations of the gage within the connector.

Note

Gage

Accuracy

Averaging a minimum of three readings, each taken after a quarter-turn rotation of the gage, reduces measurement variations that result from the gage or the connector face not being exactly perpendicular to the center axis.

Connector gages are only capable of performing coarse measurements. They do not provide the degree of accuracy necessary to precisely measure the pin depth

the kit devices. This is partially due to the repeat-

ability 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, however, 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 &HMO1 inch due to systematic (biasing) errors usually resulting from worn gages and gage masters, therefore, these systematic errors were not included in the uncertainty analysis. As the gages endure more use, the systematic errors could become more significant in the accuracy of the measurement.

When to

Gage Connectors

Gage a connector at the following times:

Before you use it for the first time. It is recommended that you record the initial pin depth measurement of your device to compare with future readings. This serves as a good troubleshooting tool when you suspect damage may have occurred to the device.

Note

Check gages often to make sure that the zero setting has not changed. Generally, when the pointer on a recently zeroed gage does not line up exactly with the zero mark, the gage or gage master needs cleaning. Clean both of these carefully and check the zero setting again.

MAKING CONNECTIONS

Good connections require a skilled operator. Because of instrument sensitivity and coaxial connector mechanical tolerances, slight errors in operator technique can significantly affect measurements and measurement uncertainties.

Initial Connection

CAUTION

Carefully align the connectors. As you bring one connector up to the other, and as you make the

This procedure assumes that you have taken the necessary ESD precautions, and you have already cleaned and inspected (visually and mechanically) the connectors.

actual connection, be sure the connectors align perfectly. The male connector center pin must slip

concentrically into the contact fingers of the female connector. If not, stop and begin again.

Push the connectors straight together. Do not twist or screw them together. As the center conductors mate, you may feel a slight resistance.

Engage the connector nut over the threads on the second connector. Turn only the connector nut. Let the connector nut pull the two connectors straight together.

Final Connection

CAUTION

Hand tighten the connection to be torqued.

Hold the torque wrench with your thumb and index finger behind the groove in the handle.

Tighten the connection until the handle begins to break loose.

When making connections with the calibration modules, turn the nut on the connector, never turn the module itself. Doing so may cause damage to the module or to the attaching connector.

It is

not necessary to fully break the

handle of the torque wrench to reach the specified torque (Figure 4-6).

HOW

HEWLETT-PACKARD VERIFIES THE DEVICES IN THIS

KIT

Hewlett-Packard verifies the specifications of these devices as follows: The residual microwave error terms of the test system are verified with precision airlines and shorts, or

low frequency resistance. The resistance is traceable to NIST (United States 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 a very accurate electrical representation. The mechanical measurements are traceable to NIST through various plug and ring gages and other mechanical measurements.

Each calibration device is electrically tested on this test system to the specifications listed in this manual. These two steps establish a traceable link to NIST for Hewlett-Packard to the extent allowed by the Insti-

tute’s calibration facility. The devices in this kit are traceable to NIST through Hewlett-Packard.

Before You Start:

Proper connector care and connection techniques are critical for accurate, repeatable measurements.

Refer to the calibration kit documentation for care infromation. Prior to making connections to the network analyzer, carefully review the information about inspecting, cleaning, and gaging connectors.

Having good connector care and connection techniques extends the life of these devices. In addition, you obtain the most accurate measurements.

This type of information is typically located in Chapter 3

of the calibration kit manuals.

For additional connector care instruction, contact your

local Hewlett-Packard Sales and Service Office about
