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

The 85036B calibration kit contains the following:

• one male and one female 75Ω type-N open termination

• one male and one female 75Ω type-N short termination

• one male and one female 75Ω t ype-N load

• three 75Ω type-N to 75Ω type-N adapters Refer to T able 6-1 and Figure 6-1 for a complete list of kit contents and their associated

part n u mbers .

The 85036E calibration kit contains t he following:

• one male combination open/short termination

• one male 75Ω type-N load Refer to T able 6-2 and Figure 6-2 for a complete list of kit contents and their associated

part n u mbers .

Broadband Loads

The broadband loads a re inst rument-grade, 75Ω terminat ions 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 repeatabl e connection s .

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.

General Information

Calibration Kit Overview

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, repea table connections. The b eads are des i gned 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 performing a calibration.

The calibration definitions can be:

• resident within the analyzer

• entered from the front panel

Installation of the Calibration Definitions

The calibration definitions for the kit may be permanently installed in the internal memory or hard disk of the network analyzer.

If the calibration definitions for the kit are not permanently installed in the network analyzer, they must be manually entered. Refer to your network analyzer user’s guide for instructions.

Equipment Required but Not Supplied

Gages, torque and open-end wrenches, ESD protective devices, and various connector cleaning supplies are not included in the calibration kit but are required to ensure successful operation of the calibration kit. Refer to Table 6-3 on page 6-5 for ordering information

Incoming Inspection

Verify that the shipment is complete by referring to Figure 1-1 o n p age 1-5. Check for damage. The foam-lined storage case provides protection during shipping. If the case or any device appears damaged, or if the shipment is incomplete, contact

Agilent. See Table 5-1 on page 5-3. Agilent will arrange for repair or replacement of incomplete or damaged shipments without waiting for a settlement from the transportation company.

When you send the kit or device to Agilent, in clude a service tag (found near the end of this manual) with the following information:

• your company name and address

• the name of a technical contact person within your company, and the person's complete phone number

• the model number and serial number of the kit

• the part number and serial number of the device

• the type of service required

•a detailed description of the problem

Recording the Device Serial Numbers

In addition to the kit serial number, the devices in this kit are individually serialized (serial numbers are labeled onto the body of each device). Record these serial numbers in

Table 1-1 for the 850 36B and Table 1-2 for the 85036E. Recording the serial numbers will

prevent confusing the devices in this kit with similar devices in other kits.

Calibration Kits Documented in this Manual

This manual applies to any 85036B or 85036E calibration kit whose serial prefix is listed on the title page. If your calibration kit has a different serial number prefix than the one listed on the title page, refer to “Calibration Kit History” below for information on how this

manual applies.

Calibration Kit History

This section describes calibration kits with serial number prefixes different than those listed on the title page.

Agilent 8 5036B kits with serial prefix 3102A and below

• 75 ohm load specification: return loss ≥ 45 db, dc to 2 GHz

• all other kit components unspecified 85036B calibration kits with serial number prefix 3102A and below should meet the

specifications published in this manual. If you wish to have your kit recertified to current specifications, contact your nearest Agilent service center. For contact information, see

Table 5-1 on page 5-3.

Agilent 8 5036B 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 steps 1 through 3 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 Sex of a Connector

In this manual, the s ex of c a li bra tion de vices a nd ada pt ers ar e r ef erred to in terms of their connector interface. For example, a male open has a male connector.

However, during a measurement calibration, the network analyzer softkey menus label a

type-N 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) on the analyzer’s display refers to the short that is to be connected to the female test port. This will be a male short from the calibration kit.

Conversely, connector gages are referred to in terms of the connector that it measures. For instance, a male connector ga ge has a female connector on the gage so that it can measure male dev ices.

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 2-3 on page

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

Temperature—What to W atch 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.
