Verification Kit Overview

The Agilent 85057B 2.4 mm verification kit provides a set of standards with known characteristics, traceable to a reference (golden) standard in Agilent Technologies calibration lab. This set of standards is used to verify your measurement calibration and also to verify that your PNA system is operating within its specifications. The frequency range covered by the 85057B is from 45 MHz to 50 GHz.

Kit Contents

The 85057B verification kit includes the following items:

• 20 dB attenuator

• 40 dB attenuator

•25 mismatch airline

•50 airline

• storage box

• User’s and Service Guide (this manual)

• USB drive that contains factory-measured verification data for use with the PNA system verification process

• data sheet for each device that contains factory-measured verification data

• anti-virus scan report

Refer to Chapter 6, “Replaceable Parts,” for a complete list of replaceable part numbers.

IMPORTANT Backup copies of the data sheets, anti-virus scan reports, and the data contained on the USB

drive should be made immediately upon receipt of the verification kit.

NOTE A file containing the verification data for your kit is maintained for one year from the time of

measurement. If you lose this data, contact Agilent. See “Contacting Agilent” on page 5-7.

Calibration Definitions

The 85057B verification kit is intended to be used with the 85056A 2.4 mm calibration kits. Prior to performing a calibration with your PNA, the calibration kit must be selected and the calibration definitions for the devices in the kit installed in the PNA. Refer to your PNA Help system for instructions on selecting the calibration kit and performing a calibration.

Installation of the Calibration Definitions

The calibration definitions for the kit should be permanently installed in the internal memory or hard disk of the PNA. They may already be resident within the analyzer, or you can download them from Agilent’s Calibration Kit Definitions Web page at www.na.tm.agilent.com/pna/caldefs/stddefs.html. In addition, the calibration definitions may be entered manually from the front panel. Refer to your PNA Help system for

instructions.

Equipment Required but Not Supplied

Certain items are required or recommended for successful operation of the verification kit but are not included in the kit. Refer to Table on page 6-3 for ordering information.

Incoming Inspection

Verify that the shipment is complete by referring to the contents list in the shipping container.

Check for damage. The foam-lined storage case provides protection during shipping. Verify that this case and its contents are not damaged.

If the case or any device appears damaged, or if the shipment is incomplete, refer to “Contacting Agilent” on

page 5-7. Agilent will arrange for repair or replacement of incomplete or damaged shipments without

waiting for a settlement from the transportation company. Refer to “Returning a Kit or Device to Agilent

Technologies” on page 5-6 for instructions.

Recording the Device Serial Numbers

In addition to the kit serial number, the devices in this kit are individually serialized (serial numbers are labeled into the body of each device). Record these serial numbers in Ta bl e 1 - 1. Recording the serial numbers will prevent confusing the devices in this kit with similar devices from other kits.

General Information

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 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.
