1 General Information 1- 1
General Information Calibration Kit Overview 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.
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, repeatable connections. The beads are designed to minimize return loss and are separated far enough so that interaction between the beads is minimized.
General Information Incoming Inspection Incoming Inspection Verify that the shipment is complete by referring to Figure 1-1 on page 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.

General Information Recording the Device Serial Numbers 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 85036B 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.
General Information Calibration Kits Documented in this Manual 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.
General Information Clarifying the Sex of a Connector Clarifying the Sex of a Connector In this manual, the sex of calibration devices and adapters are referred 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.

3 Use, Maintenance, and Care of the Devices 3-1
Use, Maintenance, and Care of the Devices Electrostatic Discharge 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.
Use, Maintenance, and Care of the Devices Visual Inspection 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; a magnifying device with a magnification of ≥10× is recommended.
Use, Maintenance, and Care of the Devices Cleaning Connectors Inspect the Precision Slotless Connectors (female) Precision slotless female connectors are used to improve accuracy. The slotless contacts are not affected by the slight variations in male contact pin diameter. However, it is still advisable to inspect them regularly for damage. NOTE Inspection is particularly important when mating nonprecision to precision devices.
Use, Maintenance, and Care of the Devices Cleaning Connectors 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 part numbers for isopropyl alcohol and cleaning swabs. a. Apply a small amount of isopropyl alcohol to a lint-free cleaning swab. b. Clean the connector threads. c.
Use, Maintenance, and Care of the Devices Connections 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.
Use, Maintenance, and Care of the Devices Connections Table 3-1 Torque Wrench Information Connector Type Torque Setting Torque Tolerance Type-N 135 N-cm (12 in-lb) ±13.5 N-cm (±1.2 in-lb) 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.
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.
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.
Use, Maintenance, and Care of the Devices Handling and Storage 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.

A Standard Definitions A-1
Standard Definitions Standard Class Assignments Standard Class Assignments Class assignment organizes calibration standards into a format compatible with the error models used in the measurement calibration. A class or group of classes corresponds to the systematic errors to be removed from the measured network analyzer response. Table A-1 lists the classes of the devices in this calibration kit.
Standard Definitions Standard Class Assignments Blank Form The standard class assignments listed in Table A-1 may be changed to meet your specific requirements. Table A-2 is provided to record the modified standard class assignments.
Standard Definitions Nominal Standard Definitions Nominal Standard Definitions Standard definitions provide the constants needed to mathematically model the electrical characteristics (delay, attenuation, and impedance) of each calibration standard. The nominal values of these constants are theoretically derived from the physical dimensions and material of each calibration standard, or from actual measured response. These values are used to determine the measurement uncertainties of the network analyzer.
