General Information
Calibration Kit Overview
Calibration Kit Overview
The Agilent 85052D 3.5 mm calibration kit is used to calibrate Agilent network analyzers
up to 26.5 GHz for measurements of components with 3.5-mm connectors.
Kit Contents
The 85052D calibration kit includes the following items:
• user’s and service guide
• offset opens and shorts, and broadband loads
• three 3.5 mm adapters
• 5/16 in, 90 N-cm (8 in-lb) torque wrench
• 7 mm open-end wrench
• data disks that contain the calibration constants of the devices in the calibration kit.
NOTE A backup copy of each data disk and printout should be made immediately
upon receipt of the calibration kit. Refer to your analyzer user’s guide for
instructions on duplicating a disk.
For measurement convenience, the kit also contains three 3.5 mm adapters. The adapters
are primarily intended for use in measuring non-insertable devices, but can also be used as
a connector saver.
Refer to Chapter 6 , “Replaceable Parts.” for a complete list of kit contents and their
associated part numbers.
Broadband Loads
The broadband loads are metrology-grade terminations that have been optimized for
performance up to 26.5 GHz. The rugged internal structure provides for highly repeatable
connections. A distributed resistive element on sapphire provides excellent stability and
return loss.
Offset Opens and Shorts
The offset opens and shorts are built from parts that are machined to the current
state-of-the-art in precision machining.
The offset short’s inner conductors have a one-piece construction, common with the
shorting plane. The construction provides for extremely repeatable connections.
The offset opens have inner conductors that are supported by a strong, 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. The lengths of the offsets in the opens and shorts
are designed so that the difference in phase of their reflection coefficients is approximately
180 degrees at all frequencies.

85052D 1-3
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 and to ensure stable, repeatable connections.
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 prior to performing a calibration. In addition, the
calibration definitions for the devices in the kit must be installed in the analyzer if not
permanently stored in the internal memory or hard drive.
The calibration definitions can be:
• recalled from the analyzer (if stored in internal memory or the hard drive)
• loaded from the provided disk
• entered from the front panel (polynomial models only)
Refer to your network analyzer user’s guide (8510 family) or online Help (PNA family) for
instructions on selecting the calibration kit, installing (if necessary) the calibration
definitions, and performing a calibration.
Equipment Required but Not Supplied
Some items are required or recommended for successful operation of your kit, but are not
supplied with the kit. Refer to Table 6-2 on page 6-3 for a list of these items and for
ordering information.

Incoming Inspection
Incoming Inspection
Refer to Chapter 6 , “Replaceable Parts.” to verify a complete shipment. Use Table 1-1 to
record the serial numbers of all serialized devices in your kit.
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, refer to “Contacting
Agilent” on page 5-4. Agilent will arrange for repair or replacement of incomplete or
damaged shipments without waiting for a settlement from the transportation company.
See "Returning a Kit or Device to Agilent," on page 5-3.
Recording the Device Serial Numbers
In addition to the kit serial number, the devices in the kit are individually serialized (serial
numbers are labeled onto the body of each device). Record these serial numbers in
Table . Recording the serial numbers will prevent confusing the devices in this kit with
similar devices from other kits.
The adapters included in the kit are for measurement convenience only and are not
serialized.

Calibration Kits Documented in This Manual
This manual applies to any 8552B calibration kit with serial number prefix 3106A. If your
calibration kit has a different serial number prefix, refer to the next section for
information on how this manual applies.
Calibration Kit History
This section describes calibration kits with serial number prefixes lower that the ones
listed on the title page.
85052D Kits with Serial Prefix 3027A
These calibration kits did not have the calibration constants disk to support the Agilent
8510C network analyzer. The part numbers provided in this manual are the recommended
replacement parts for these kits. The devices in these kits should meet the specifications
published in this manual.
Clarifying the Sex of a Connector
In this manual and in the prompts of the PNA calibration wizard, the sex of calibration
devices and adapters is referred to in terms of the calibration device connector. For
example, the label OPEN –m– refers to a male open with a male connector.
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.
Connector gages are 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 the kit include:
• routine visual inspection
• cleaning
• proper gaging

1-6 85052D
General Information
Preventive Maintenance
• 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 the observed limits (see Table 2-2 on page 2-4) or from bad connection
techniques, can also damage these devices.

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 shown in
Table 2-1.
IMPORTANT Avoid unnecessary handling of the devices during calibration because your
fingers are a heat source.

Mechanical Characteristics
Mechanical Characteristics
Mechanical characteristics such as center conductor protrusion and pin depth are not
performance specifications. They are, however, important supplemental characteristics
related to electrical performance. Agilent Technologies verifies the mechanical
characteristics of the devices in the kit with special gaging processes and electrical testing.
This ensures that the device connectors do not exhibit any center conductor protrusion or
improper pin depth when the kit leaves the factory.
“Gaging Connectors” on page 3-6 explains how to use gages to determine if the kit devices
have maintained their mechanical integrity. Refer to Table 2-2 for typical and observed pin
depth limits.
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 states: either protruding or recessed.
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.
Figure 2-1 Connector Pin Depth

Specifications
Mechanical Characteristics
The pin depth value of each calibration device in the kit is not specified, but is an
important mechanical parameter. The electrical performance of the device depends, to
some extent, on its pin depth. The electrical specifications for each device in the kit take
into account the effect of pin depth on the device’s performance. Table 2-2 lists the typical
pin depths and measurement uncertainties, and provides observed pin depth limits for the
devices in the kit. If the pin depth of a device does not measure within the observed pin
depth limits, it may be an indication that the device fails to meet electrical specifications.
Refer to Figure 2-1 for a visual representation of proper pin depth (slightly recessed).

Use, Maintenance, and Care of the Devices
Electrostatic Discharge
Electrostatic Discharge
Protection against electrostatic discharge (ESD) 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 (DUT),
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.
Figure 3-1 shows a typical ESD protection setup using a grounded mat and wrist strap.
Refer to Table 6-2 on page 6-3 for information on ordering supplies for ESD protection.
