Calibration Kit Overview
Calibration Kit Overview
The Keysight 85033E 3.5 mm calibration kit is used to calibrate Keysight network analyzers for
measurements of components with 3.5 mm connectors up to 9 GHz.
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 illustration in Chapter 7 to verify the items in your shipment.
If your shipment is not complete, contact Keysight Technologies - refer to ‘v.
Refer to Table 6-1 on page 6-4 for part numbers of kit contents.
Broadband Loads
The broadband loads are metrology-grade, 50 ohm terminations which 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 which 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 which 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.
Open-Short-Load Holders
The open-short-load (OSL) holders are included for your convenience. The OSL holders allow you to keep
all of the calibration devices in two handy assemblies. Load each OSL holder with calibration devices of the
same connector sex so that you can perform a calibration with just one assembly. Use the 2.5 mm hex key
included with this kit to secure the calibration devices in the holders. See Figure 1-1 on page 1-3.

Recording the Device Serial Numbers
Recording the Device Serial Numbers
In addition to the kit serial number, the devices in this kit are individually serialized (serial numbers are
labeled onto the body of each device). Record these serial numbers in Ta bl e 1 - 1 . This can help you avoid
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.

Precision Slotless Connectors
Precision Slotless Connectors
The female 3.5 mm connectors in this calibration kit are metrology-grade, precision slotless connectors
(PSC). A characteristic of metrology-grade connectors is direct traceability to national measurement
standards through their well-defined mechanical dimensions.
Conventional female center conductors are slotted. When mated, the female center conductor is flared by
the male pin. Because physical dimensions determine connector impedance, electrical characteristics of
the female connector (and connection pair) are dependent upon the mechanical dimensions of the male
pin. While connectors are used in pairs, their male and female halves are always specified separately as
part of a standard, instrument, or device under test. Because of these facts, making precision
measurements with the conventional slotted connector is very difficult, and establishing a direct
traceability path to primary dimensional standards is nearly impossible.
The precision slotless connector was developed to eliminate these problems. All PSCs are female. A PSC
incorporates a center conductor with a solid cylindrical shell that defines the outside diameter of the
female center pin. Its outside diameter and, therefore, the impedance in its region does not change. The
inner part provides an internal contact that flexes to accept the allowed range of male pin diameters.
The calibration of a network analyzer having a conventional slotted female connector on the test port
remains valid only when the device under test and all calibration standards have identical male pin
diameters. For this reason PSC test port adapters are supplied in most calibration kits.
Precision slotless connectors have the following characteristics:
• There is no loss of traceable calibration on test ports when the male pin diameter of the connector on
the device under test is different from the male pin diameter of the calibration standard.
• The female PSC and its mating male connector can be measured and specified separately as part of the
device either is attached to.
• All female connectors can have a known, stable impedance based only on the diameters of their inner
and outer conductors.
• Female calibration standards can be fully specified. Their specifications and traceability are unaffected
by the diameter of the male mating pin.
• A fully traceable performance verification is made using a precision 50 ohm airline having a PSC.
• Measurement repeatability is enhanced due to non-changing connector characteristics with various pin
diameters.
With PSCs on test ports and standards, the percentage of accuracy achieved when measuring at 50 dB
return loss levels is comparable to using conventional slotted connectors measuring devices having only 30
dB return loss. This represents an accuracy improvement of about 10 times.

General Information
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 sex 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.
Table 1-2 Clarifying the Terminology of Connectors: Examples
Terminology Meaning
Short
–f–
Short (f) Male short (male center conductor) to be connected to female port
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.
Female short (female center conductor)
Preventive Maintenance
The best techniques for maintaining the integrity of the devices in the 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 bad connection techniques, can also damage these
devices.

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