1. General Information
This User Manual is valid for the Calibration Kit
 19CK010-150 (Industrial Version)
1.1 Calibration Kit Normal Use
Calibration Kits are used as an accessory for Vector Network Analyzers (VNA) 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 40 GHz for measurements of components
with SMP connectors.
RPC-2.92 to SMP adapters are included in this calibration kit to interface with standard
2.92 mm, K or 3.5 mm test port cables and VNAs.
1.2 Warnings
The calibration standards of this calibration kit are mechanically extremely sensitive devices.
High accelerations e.g. when falling down or high forces to the connector fingers will damage
them.
When connecting and disconnecting male and female connectors keep them in a straight line as
much as possible. Radial misalignment (more than permitted) stresses the fingers of the female
outer conductor significantly and leads to bent or broken fingers. This results in a very unstable
or bad RF performance.
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 of the RPC-2.92 interfaces to the recommended torque with
a torque wrench (e.g. Rosenberger 03W021-000) while holding the RPC-2.92 female counter-
part with a wrench (e.g. Rosenberger Combi Wrench 03W021-000). 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.

2. Specifications
2.1 Environmental Requirements
The electrical performance of vector network analyzers and test port cables are sensitive to am-
bient 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 in the specific
data sheets.
3. Standard Definitions
3.1 Standard Definitions
Standard definitions provide the data needed to mathematically describe the electrical charac-
teristics of each calibration standard. For this calibration kit 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 meas-
ured 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.
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 man-
ual.
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 meas-
urements.
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 in-
strument to be calibrated. The calibration process employs a technique called vector error cor-
rection, in which error terms are characterized using known standards so that errors can be re-
moved 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 analyz-
er).
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 fol-
lowing 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 tech-
nique 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.
Recommendation:
The TRM calibration is the recommended calibration method to use as two-port calibra-
tion. It can be used in a SMP male-male, female-female and male-female test port config-
uration.
The standard definition files for the VNAs include a special ‘Reflect’ device, please use it
for a TRM calibration. If no file for the specific VNA is available the standard definitions for
all calibration standards have to be entered manually. The ‘Reflect’ device is derived from
the short calibration standard but the L0, L1, L2 and L3 are all set to zero. This keeps the
symmetry of the ‘Reflect’ that is necessary for the TRM calibration.
Calibration Procedure
The procedures to perform a VNA calibration are very different between the VNA models. Mod-
ern 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 or aligned correctly
There might be defects
 VNA, e.g. mechanically overloaded test port
 Instable test port cables
 Mechanically overloaded load
 Bent or broken contact fingers
There is no Verification Kit available for SMP connectors. So additional loads and adpaters can
be used to verify the quality of reflection and transmission measurements or short cable assem-
blies of high quality may be used to check for plausible measurement results. This should be
done from time to time to identify defects.

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 Inspection
Optically check the connector mating planes, contact pins and contact fingers. Specially the
outer conductor of the female SMP connector are very sensitive for bent or broken contact fin-
gers, resulting in very unstable or bad RF performance.
6.1.2 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 edg-
es 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 checked 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.

6.1.3 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 micro-
wave 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 com-
pressed air.
 Clean surfaces using Isopropanol on cotton swabs or lint free cloth. Use only sufficient sol-
vent to clean the surface. When using swabs or lint free cloth, use the least possible pres-
sure to avoid damaging connector surfaces. Do not spray solvents directly on to the con-
nector 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.
6.1.4 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 specifica-
tions. 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 indi-
cates incorrectness and incompatibility. There are some dimensions that are critical for the me-
chanical 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 Gauging
There are no special Rosenberger gauges available for SMP connectors.
It is recommended to use a Caliper (e.g. Mitutoyo ID-F150H)
.
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.

6.3 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 com-
mon cause of connector damage during storage.
 Keep connectors clean.
 Do not touch mating plane surfaces or the contact fingers. Natural skin oils and microscopic
particles of dirt are easily transferred to a connector interface and are very difficult to remove.
The wearing of protective gloves is recommended.

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.
The wearing of protective gloves is strongly recommended for every single connection. Even the
smallest amount of skin lipids/particles that gets into the connector interface can have a strong
influence on the measurements and even make them unusable.
Adapting Test Ports
The calibration kit comes with two RPC-2.92 to SMP adapters to adapt the test port of the VNA
or the 2.92 mm test port cable to SMP interfaces.
How to connect
Pick up the calibration standard. Make sure that the test port cable and the calibration standard are
aligned with each other. Carefully guide it to the test port cable until you are fully centred and you
feel the male and female SMP connectors touching each other. Now the force can be gradually in-
creased until the SMP connection snaps into place.
The test port cable and the calibration standard
are aligned with each other. The test port cable and the calibration standard are not aligned with each other. A strong me-
chanical stress will be caused.

Make sure that the mated connection is kept free of mechanical stress. Even slight me-
chanical stresses can then lead to different contact situations at one or more contact la-
mellae, which in turn can result in different measurement results.

If a mated connection is bent too much, contact lamellae are permanently deformed or in
the worst case they break out. The contact force of the lamellae concerned decreases
considerably or there is no contact at all.

should be taken not to get hurt during this process and to keep the test port cable and the calibra-
tion standard under control.
Take the test port cable with one hand and the calibration standard in the other hand. Touch the
forefingers and the thumbs. Gradually increase the disconnecting force between these fingers.
