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.
Kit Contents
Use the Contents List in the shipping container to verify the completeness of your
shipment. Although this list is the most accurate, you can also use the illustrations in
Chapter 7 to verify the items in your shipment. If your shipment is not complete, contact
Agilent Technologies - refer to “Contacting Agilent” on page 5-4.
Refer to Table 6-1 and Table 6-2 for a list of kit contents part numbers.
Broadband Loads
The broadband loads are instrument-grade, 75Ω terminations 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 repeatable connections.
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.
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.
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

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 the steps 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).

Clarifying the Terminology of a Connector Interface
Clarifying the Terminology of a Connector Interface
In this document and in the prompts of the PNA calibration wizard, the gender 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.
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 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 2-2 on page
2-3), or from bad connections, can also damage these devices.

General Information
When to Calibrate
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 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.

Temperature—What to Watch 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.

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. 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 MΩresistor 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 protective devices.

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.
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. Look especially for deep scratches or dents, and for dirt and metal
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.
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.

Use, Maintenance, and Care of the Devices
Cleaning Connectors
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.
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 “Electrostatic Discharge”
earlier in this chapter for additional information.
2. Clean the Connector Threads
WARNING Keep isopropyl alcohol away from heat, sparks, and flame. Store in a
tightly closed 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.
