1. General Information
This User Manual is valid for the Calibration Kits
• P5CK14A-170 (Full Version)
• P5CK010-170 (Industrial Version)
• Customer specific RPC-N 75 ΩCalibration Kits
These Calibration Kits do not contain gauges. It is good lab practice to check unknown devices with a
suitable connector gauge for N 75 Ω before connecting them to any calibration standard of the
mentioned Calibration Kits or a test port of a Vector Network Analyzers (VNA). We recommend to use
Rosenberger Gauge Kit P5GK0KS-010 or comparable ones.
For customer specific Calibration Kits all VNA calibration methods may not be available.
1.1 Calibration Kit Normal Use
Calibration Kits are used as an accessory for VNAs to perform vector-error correction. Vector-error
correction is the process of characterizing systematic errors of the measurement system by
measuring known calibration standards, and then mathematically removing the effects of these
errors from subsequent measurements. The measurement accuracy of the calibrated VNA
depends mainly on the quality of the calibration kit used. Contributing factors are noise, linearity
and temperature stability of the VNA, transmission and reflection stability of a test port cable as
well as operator experience and care.
VNAs usually offer several techniques for correcting systematic measurement errors. The
standards in this calibration kit allow you to perform one-port OSL (OSM) or two-port OSLT
(TOSM) and TRM (TMR) calibrations from DC up to 12 GHz for measurements of components with
RPC-N 75 Ωconnectors.
Components with other N 75 Ωconnectors are mechanically compatible and can also be
measured.

1.2 Warnings
The calibration standards and the gauges of this calibration kit are mechanically sensitive devices.
High accelerations e.g. when falling down will damage them.
Connect the calibration standards only to test ports and other devices that have been cleaned and
checked for gauge, concentricity and integrity of the contact fingers. Detailed procedures are
described in Chapter 6 and 7.
Tighten the connector coupling nuts to the recommended torque with the torque wrench. Do not
over torque!
Consider the power applied to the Load calibration standards. Maximum power limits for the sum of
RF and DC power are defined in the specific data sheets.
It is good lab practice to use at least an ESD wrist strap when handling calibration standards or
DUTs on a VNA although the calibration standards themselves are not ESD sensitive. Please
consult your VNA manual.
Follow further limitations given in the specific data sheets.
Never connect RPC-N 75 Ω connectors to RPC-N 50 Ωor other type N 50 Ωconnectors.
Specially the RPC-N 75 Ωfemale center conductor will be be destroyed by an 50 Ωmale
center conductor.

2. Specifications
2.1 Environmental Requirements
The electrical performance of vector network analyzers and test port cables are sensitive to
ambient temperature drift. Most manufacturers limit the allowable temperature drift to ± 1 K during
measurement calibration and during measurements when the network analyser error correction is
turned on. For further information please refer to the VNA specifications.
NOTE: With your fingers being a heat source, avoid unnecessarily handling the devices
during calibration.
The calibration standards are less sensitive to temperature changes. The operating temperature
range for which the specifications are valid is defined in the specific data sheets.
2.2 Electrical and mechanical Specifications
Electrical and mechanical specifications are defined for all calibration standards and the torque
wrench in the specific data sheets.
3. Standard Definitions
3.1 Standard Definitions
Standard definitions provide the data needed to mathematically describe the electrical
characteristics of each calibration standard. Two types of standard definitions are available:
•Model based (standard delivery): These are the traditional standard definitions and can be
used on both old and modern VNAs. The values of these constants are theoretically derived
from the physical dimensions and material of each calibration standard, or from actual
measured response. All necessary values are printed on the Standard Definition Cards and
stored as data files on an USB stick. Both are included with this calibration kit.
•Data based (optional): These standard definitions allow more accurate measurements but can
only be used on modern VNAs. They consist of a set of complex measurement values for each
calibration standard in a narrow frequency step size. A file containing these values for all Open,
Short and Load calibration standards is delivered on an USB stick.
These standard definitions are used in the calibration of the VNA to determine the systematic
errors of the measurement system. Please always use the most recent source of information
(Standard Definitions Cards or VNA specific files).

3.2 Installation of Standard Definitions
The standard procedure to install Standard Definitions is to import them from the USB stick onto
your VNA. As standard delivery data files for Vector Network Anaylzer Families PNA
(Keysight/Agilent) and ZVA (Rohde&Schwarz) are included. Data files for other VNA families are
available on request. If the specific data file is not available, the standard definitions have to be
installed manually with the provided information from the Standard Definitions Cards.
•USB-stick
The Kit Info Card gives a brief description for the VNAs described above.
For all others please consult the VNA operating manual.
•Manual installation
The manual installation is a more complex process. Please consult the VNA operating manual.
Some network analyzers allow a step by step input of the model based standard definitions
during the VNA calibration without previously loading them.
•Updating
After a re-calibration the standard definitions are optimized on the basis of the actual
measurements.
Data files have to be imported like described before.
For a manual update only the values that have changed have to be modified.
3.3 Standard Definitions file nomenclature
The file name includes the calibration kit type, the serial number, the type of standard definitions
and the date of calibration. The file extension defines the VNA types the file can be used on. For
further Information see the Application Note AN001.

4. VNA Calibration
4.1 VNA Calibration
A VNA is only as useful as the accuracy of the measurements it makes, and this requires the
instrument to be calibrated. The calibration process employs a technique called vector error
correction, in which error terms are characterized using known standards so that errors can be
removed from actual measurements. The process of removing these errors requires the errors and
measured quantities to be measured vectorially (thus the need for a vector network analyzer).
Main setting parameters:
It is good practice to start your measurement by selecting the main setting parameters.
•Sweep type (linear / logarithmic)
•Sweep range (start frequency / stop frequency)
•Number of points (frequency step size)
•Source power
•IF bandwidth (small IF bandwidth basically increases the dynamic range)
•Sweep time
Connect test port cables and adapters to your VNA as needed for your specific measurement task.
Calibration techniques
A very large number of calibration techniques have been developed to calibrate a VNA. The
following list describes calibration techniques you can apply with this calibration kit along with their
features and applicability for use in specific situations.
One-port calibration
OSL (OSM) Open-Short-Load (Open-Short-Match)
When only reflection measurements are needed, the fastest and easiest calibration
technique is OSL. It requires 3 connections of calibration standards on the reference plane.
Two-port calibrations
OSLT (TOSM) Open-Short-Load-Thru (Thru-Open-Short-Match)
OSLT is the most commonly used two-port calibration method. The Thru connections are
performed by using well-known, precision calibration adapters in male-male or female-female
configuration or as a direct connection of the male and the female test ports.

TRM (7-term) Thru-Reflect-Match
The male and female Short standards of this kit are designed with the same offset length. So
the TRM calibration technique can be used. It requires high reflects with a symmetrical
reflection during VNA calibration on both test ports. TRM needs less connections during
calibration than OSLT and UOSM.
UOSL (SOLR) (7-term) Unknown-Open-Short-Load (Short-Open-Load- Reciprocal)
The UOSM technique is similar to the OSLT calibration but doesn’t need well-known
adapters. Even a low loss Device under Test (DUT) can be sufficient as Thru standard. The
UOSM technique is particularly well suited for calibration involving different connector types
at the test ports and is most effective when data based standards are available.
In cases when the two VNA test ports have different connector systems installed,e.g. RPC-N
75 Ωand RPC-N 50 ΩUOSM can handle this situation. A second calibration kit is needed.
Calibration Procedure
The procedures to perform a VNA calibration are very different between the VNA models. Modern
VNA often guide you thru the settings and actions. For details please consult the manual of your
specific VNA.
4.2 Calibration Check
It is advisable to check the calibration after error correction has been performed, particularly when
test port cables and adapters have been used.
During the calibration
•Calibration standards can easily be mixed up
•Connections may not be tightened correctly
There might be defects
•VNA, e.g. mechanically overloaded test port
•Instable test port cables
•Mechanically overloaded load
•Bent or broken contact fingers
With a Verification Kit, reflection and transmission measurements can be checked in a wide
frequency range for DUTs with low and high reflections and low and medium insertion loss. Actual
measurement values can be compared to reference values delivered with the Verification Kit
standards. This should be done from time to time to identify defects.
Air Lines, Precision Adapters and Mismatch Standards can also be used as a faster method for
more frequent checks.

6. Use, Maintenance and Care
6.1 Connector Care
It is of particular importance to note that mechanical damage can be inflicted on a connector while
making a connection or a disconnection.
6.1.1 Connector Cleaning
To ensure a long and reliable connector life, careful and regular inspection of connectors is
necessary and cleaning of connectors is essential to maintain good performance.
Connectors should be inspected initially for dents, raised edges, and scratches on the mating
surfaces. Connectors that have dents on the mating surfaces will usually also have raised edges
around them and will make less than perfect contact; further to this, raised edges on mating
interfaces will make dents in other connectors to which they are mated. Connectors should be
replaced unless the damage is very slight.
Awareness of the advantage of ensuring good connector repeatability and its effect on the overall
uncertainty of a measurement procedure should encourage careful inspection, interface gauging
and handling of coaxial connectors.
Prior to use, a visual examination should be made of a connector or adaptor, particularly for
concentricity of the centre contacts and for dirt on the mating planes. It is essential that the axial
position of the centre contact of all items offered for calibration should be gauged because the
adjoining surfaces of mated centre contacts must not touch. If the centre contacts do touch, there
could be damage to the connector or possibly to other parts of the device to which the connector is
fitted.
Small particles, usually of metal, are often found on the inside connector mating planes and on the
threads. They should be removed to prevent damage to the connector surfaces. The items
required for cleaning connectors and the procedure to be followed is described below.
6.1.2 Cleaning procedure
Items required:
•Low pressure compressed air (solvent free).
•Cotton swabs.
•Lint free cleaning cloth.
•Isopropanol.
•Illuminated magnifier or microscope (factor 5 to 10)
NOTE: Isopropanol that contains additives should not be used for cleaning connectors as
it may cause damage to plastic dielectric support beads in coaxial and microwave
connectors. It is important to take all necessary safety precautions when using
chemicals or solvents.

•Remove loose particles on the mating surfaces and threads etc. using low-pressure
compressed air.
•Clean surfaces using Isopropanol on cotton swabs or lint free cloth. Use only sufficient solvent
to clean the surface. When using swabs or lint free cloth, use the least possible pressure to
avoid damaging connector surfaces. Do not spray solvents directly on to the connector surfaces
or use contaminated solvents.
•Use the low-pressure compressed air once again to remove any remaining small particles and
to dry the surfaces of the connector to complete the cleaning process before using the
connector.
6.1.3 Cleaning connectors on static sensitive devices
Special care is required when cleaning connectors on test equipment containing electrostatic
sensitive devices. When cleaning such connectors always wear at least a grounded wrist strap and
observe correct procedures.
6.2 Interface Dimensions and Gauging
It is of the utmost importance that connectors do not damage the test equipment interfaces to
which they are connected. Poor performance of many coaxial devices and cable assemblies can
often be traced to poor construction and non-compliance with the mechanical specifications. The
mechanical gauging of connectors is essential to ensure correct fit and to achieve the best
performance. This means that all coaxial connectors fitted on all equipment, cables and
terminations etc. should be gauged on a regular basis in order to detect any out of tolerance
conditions that may impair the electrical performance.
6.2.1 Gauging connectors
A connector should be gauged before it is used for the very first time or if someone else has used
the device to which it is connected.
If the connector is to be used on another item of equipment, the connector on the equipment to be
tested should also be gauged.
Connectors should never be forced together when making a connection since forcing often
indicates incorrectness and incompatibility. There are some dimensions that are critical for the
mechanical integrity, non-destructive mating and electrical performance of the connector.
The mechanical gauging of coaxial connectors will detect and prevent the following problems:
Inner conductor protrusion
This may result in buckling of the socket contacts or damage to the internal structure of a
device due to the axial forces generated.
NOTE: At no time should the pin depth of the connector be protruding.

Inner conductor recession
This will result in poor reflection and possibly unreliable contact.
6.2.2 Gauges
The Rosenberger gauges are of screw-on type in plug and jack version. They can be used to
gauge calibration standards as well as test ports, test port cables, adapters and DUTs.
Naming convention:
A “gauge plug” (male) is used to measure a DUT with plug (male) connector. The gauge itself has
a jack (female) connector and needs a gauge block with plug (male) connector. For a “gauge jack”
(female) all gender are vice versa.
Checking devices for protrusion or excessive recession only a single measurement is sufficient.
More precise measurements or checking devices very close to critical limits should be done in
different orientations averaging up to 4 single measurements.
When a gauge block is used to initially adjust the gauge a torque spanner should be used to
tighten up the connection to the correct torque.
6.2.3 Connector gauge measurement resolution
Because of connector gauge measurement resolution uncertainties (one small division on the dial)
and variations in measurement technique from user to user connector dimensions may be difficult
to measure. Dirt and contamination can cause differences of 0.005 mm and, in addition, the way
that the gauge is used can result in larger variations. When using a gauge system for mechanical
compliance testing of connectors carry out the following procedure each time:
•Carefully inspect the connector to be tested and clean it if necessary.
•Clean and inspect the gauge and the gauge block.
•Carefully zero the gauge with the gauge block in place.
•Remove the gauge block.
•Measure the connector using the gauge and note the reading.
•Repeat the process at least once or more times as necessary.
6.2.4 Gauge blocks
Every connector gauge requires a gauge block that is used to zero the gauge before use.
Figure 6-1 shows two sets of gauges and gauge blocks for the RPC-N 75 Ωconnector.

6.3 Mechanical Specifications
Good electrical microwave connections need well-defined mechanical connector dimensions. Pin
depth and excentricity of the center conductor have a significant impact on the electrical
performance.
Pin depth is the distance the centre conductor mating plane differs from being flush with the outer
conductor mating plane (see Figure 7-2). The pin depth of a connector can be in one of two states:
either protruding or recessed.
Protrusion is the condition in which the centre conductor extends beyond the outer conductor
mating plane. This may result in buckling of the socket contacts or damage to the internal structure
of a device due to the axial forces generated.
NOTE: At no time should the pin depth of the connector be protruding.
Recession is the condition in which the centre conductor is set back from the outer conductor
mating plane. The amount of unwanted reflections is directly proportional to the pin depth.
Pin depth limits are defined for all calibration standards in the specific data sheets.

6.4 Handling and Storage
•Install the protective end caps and store the calibration devices in the foam-lined storage case
when not in use.
•Never store connectors loose in a box, or in a desk or bench drawer. This is the most common
cause of connector damage during storage.
•Keep connectors clean.
•Do not touch mating plane surfaces. Natural skin oils and microscopic particles of dirt are easily
transferred to a connector interface and are very difficult to remove.

7. Connections
Good connections require a skilled operator. The most common cause of measurement error is
bad connections. The following procedures illustrate how to make good connections.
Making a Connection
The calibration kit comes with a so-called combi-wrench which is a useful tool to make
connections. This wrench is made of plastic and helps you to hold the device body and prevent it
from rotating while making a connection.
Preliminary Connection
1. Ground yourself and all devices. Always wear a grounded wrist strap and work on a
grounded, conductive table mat.
2. Visually inspect the connectors.
3. If necessary, clean the connectors. Refer to 4.1 Connector Care.
4. Use a connector gage to verify that all centre conductors are within the observed pin depth
values in Table 2-2. Refer to 4.2 Interface Dimensions and Gaging.
5. Carefully align the connectors. The male connector centre pin must slip concentrically into
the contact finger of the female connector.
6. Push the connectors straight together and tighten the connector nut finger tight.
CAUTION:Do not turn the device body. Only turn the connector nut. Damage to the centre
conductor can occur if the device body is twisted.
Do not twist or screw the connectors together. As the centre conductors mate, there is
usually a slight resistance.
7. The preliminary connection is tight enough when the mating plane surfaces make uniform,
light contact. Do not overtighten this connection. A connection in which the outer
conductors make gentle contact at all points on both mating surfaces is sufficient. Very
light finger pressure is enough to accomplish this.
8. Make sure the connectors are properly supported. Relieve any side pressure on the
connection from long or heavy devices or cables.
9. Final Connection Using a Torque Wrench
10. Use a torque wrench to make a final connection. Table 4-2 provides information about the
torque wrench recommended for use with the calibration kit. A torque wrench is included in
the calibration kit.

How to Separate a Connection
To avoid lateral (bending) force on the connector mating plane surfaces, always support the
devices and connections.
CAUTION: Do not turn the device body. Only turn the connector nut. Damage to the centre
conductor can occur if the device body is twisted. When disconnecting a sliding load, leave the
centre conductor pullback handle in the locked position.
•Use the combi-wrench to prevent the device body from turning.
•Use torque wrench to loosen the connecting nut.
•Complete the separation by hand, turning only the connecting nut.
•Pull the connectors straight apart without twisting, rocking, or bending either of the connectors.
