General Information

Calibration Kit Overview

The Agilent 85032B and 85032E type-N calibration kits are used to calibrate Agilent

network analyzers up to 6 GHz for measurements of components with 50Ω 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.

Broadband Loads

The broadband loads are instrument-grade, 50Ω terminations that have been optimized for

performance up to 6 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

performing a calibration.
