Calibration Kit Overview
Calibration Kit Overview
The Agilent 85056A 2.4 mm calibration kit is used to calibrate Agilent network analyzers
up to 50 GHz for measurements of components with 2.4 mm connectors.
Kit Contents
The 85056A calibration kit includes the following items:
• offset opens and shorts
• broadband and sliding load terminations
• 2.4 mm adapters
• 2.4 mm gage sets
• 5/16 in, 90 N-cm (8 in-lb) torque wrench
• 7 mm open-end wrench
• data disks that contain the calibration definitions of the devices in the calibration kit
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, 50
Ω
terminations that have been optimized for
performance up to 50 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.
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, allowing
them to be used in calibration procedures for non-insertable devices.
