Calibration Kit Overview
Calibration Kit Overview
The Agilent 85032F type-N 50 Ω calibration kit is used to calibrate Agilent network
analyzer systems for measurements of components with type-N connectors up to 9 GHz.
The standards in this calibration kit allow you to perform simple 1- or 2-port calibrations.
This manual describes the 85032F calibration kit and provides replacement part numbers,
specifications, and procedures for using, maintaining and troubleshooting the kit.
NOTE
This manual assumes you practice proper connector care. For information,
refer to Chapter 3,“Use, Maintenance, and Care of the Devices.” Also refer to
the “Connector Care – Quick Reference Card,” located in the back of this
manual.
Kit Contents
The 85032F type-N calibration kit contains the following:
• offset opens and shorts, and broadband load terminations with both male and female
connectors
• a disk that contains the calibration definitions of the devices in the kit for 872x and
875x VNA systems
Broadband Loads
The broadband loads are metrology-grade, 50 Ω terminations that have been optimized for
performance up to 9 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 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.

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
1-4 85032F
port. This will be a male short from the calibration kit.

Preventive Maintenance
Short
–f–
Short (f) Male short (male center conductor) to be connected to female port
Female short (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,“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 observed limits (see
Table 2-3 on page 2-4), or from poor 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.

Specifications
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 this 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 3-7 explains how to use gages to determine if the kit devices
have maintained their mechanical integrity. (Refer to Table 2-3 on page 2-4 for typical and
observed pin depth limits).
Table 2-2 Mechanical Characteristics
Dimension Typical Value
Inside diameter of outer conductor 7.0000 ±0.0076 mm
Outside diameter of center conductor 3.0404 ±0.0051 mm
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. Some coaxial connectors (such as
2.4 mm and 3.5 mm) are designed to have these planes nearly flush. Type-N connectors,
however, are designed with a pin depth offset of approximately 5.26 mm (0.207 inch), not
permitting these planes to be flush. The male center conductors are recessed by the offset
value while the female center conductors compensate by protruding the same amount.
This offset necessitates redefining of pin depth with regard to protrusion and recession.
Protrusion refers to a male type-N connector center conductor having a pin depth value
less than 5.26 mm (0.207 inch), or female type-N connector center conductor having a pin
depth value greater that 5.26 (0.207 inch).
Recession refers to a male type-N connector center conductor having a pin depth value
greater than 5.26 mm (0.207 inch), or female type-N connector center conductor having a
pin depth value less than 5.26 (0.207 inch).
The pin depth value of each calibration device in this 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 this kit take
into account the effect of pin depth on the device’s performance. Table 2-3 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 in type-N connectors.
