1. General Information
This User Manual is valid for the Gauge Kits
• 05GK0KS-010
• P5GK0KS-010
• Customer specific RPC-N 50 Ωand RPC-N 75 Ω Gauge Kits
1.1 Gauge Kit Normal Use
Gauge Kits are used to check or measure the connector gauge of calibration standards, adapters,
test port adapter and cables for protrusion or recession of connector pins with male or female
RPC-N 50 Ωand RPC-N 75 Ω. A protruding connector pin may mechanically damage the
counterpart it is connected to, while significant recession in an RF connection degrades the RF
performance.
Checking connector gauge is a typical application in a production line and can be done very fast.
Carefully measuring connector gauge is more precise and takes some time. It is normally done in
calibration laboratories to estimate the influence of air gaps, during type approval of new products
or statistical process control.
Components with general N 50 Ω and N 75 Ω connector can also be checked or measured but with
respect to the gauge block reference length, see figure 3-2.
1.2 Warnings
The gauges of this gauge kit are mechanically sensitive devices. High accelerations e.g. when
falling down will damage them.
Observe the small gauge pointer when connecting a device. If the counter clockwise mark “0.5” is
reached stop connecting immediately to avoid damage of the gauge.
Tighten the connector coupling nuts to the recommended torque with a torque wrench. Do not over
torque!
Do not connect gauge blocks from other gauge types to the gauges of this kit
Connect the gauge blocks of this kit only to the gauges of this kit, do not connect them to anything
else like calibration standards, adapters, cables, …

3. Gauging connectors
3.1 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.
3.1.1 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.

3.1.2 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.
3.1.3 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 (please avoid overlong sentences). 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 (using several different orientations) at least once or more times as
necessary (averaging the results).

3.1.4 Gauge blocks
Every connector gauge requires a gauge block that is used to zero the gauge before use.
Figure 3-1 shows two sets of gauges and gauge blocks for the RPC-N 50 Ωand RPC-N 75 Ω
connector.

When the gauge block is connected to the gauge a zero reading (both pointers show “0”)
should be indicated.
Minor deviations from a zero reading can be compensated by turning the outer black ring
of the gauge. Significant deviations (> 0.01 mm) are suspicious and might be caused by a
misaligned gauge block or gauge.
3.1.5 Reading the gauge
With the zeroed gauge connector gauge can be measured. Connect the measurement object to
the gauge as described before. The measurement result is a combination of the reading of both
pointers. The small one (B) gives the coarse reading (scaling: 0.1 mm) and the long one (A) the
fine reading (scaling: 0.001 mm).
Small pointer (B)
Every reading above the “0” mark means a recessing centre conductor.
Every reading below the “0” mark means a protruding centre conductor.

3.2 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 3-3). 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.

3.3 Handling and Storage
•Clean and inspect the gauge and the gauge block.
•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 mating plane surfaces of the gauge and gauge block. Do not spray solvents
directly on to the surfaces or use contaminated solvents.
•Use the low-pressure compressed air once again to remove any remaining small particles and
to dry the surfaces to complete the cleaning process before using the gauge and the gauge
block.
•Do not turn the device body. Only turn the connector nut. Otherwise scratches on the mating
plane surfaces of the gauge, gauge block and DUT arise.
•Install the protective end caps and store the gauges and gauge blocks 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.
•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.
