Note the following aspects during actual use:
1) Check of connectors
It is necessary to wear an anti-static wrist strap when checking the connectors. It is recommended to use
a magnifier to check:
1) the electroplated surface for wear and deep scratches;
2) the thread for deformation;
3) the thread and joint surface for metallic particles;
4) the inner conductor for bending and breakage;
5) the screw for improper rotation.
Check the connectors so as not to damage the instrument ports
Any damaged connector may damage the good connector connected to it even for the first time of
measurement. To protect the ports of the USB CW power sensor, the connector to be used shall be
checked before connection.
2) Connection
The connectors should be checked and cleaned before measurement and connection to ensure that
they are clean and undamaged. It is necessary to wear an anti-static wrist strap during connection. The
correct connection methods and procedures are as follows:
Step 1. As shown in Figure 2.3, align the axes of the two interconnected connectors to ensure that the
pin of the male connector slides concentrically into the hole of the female connector.
Fig. 2.3 CoaxialAlignment of Interconnected Connectors
Step 2. As shown in Fig. 2.4, move both connectors straight together, so that they can be connected
smoothly; rotate the threaded sleeve of connector (rather than the connector itself) until it is tightened;
during connection, there can be no relative rotary motion both connectors;
Fig. 2.4 Connection
Step 3. As shown in Fig. 2.5, use a torque wrench to tighten the connectors and finish the connection;
the torque wrench shall not exceed the starting break point and an auxiliary wrench can be used to
prevent the connector rotating.

3) Disconnection
Step 1. Support the connector to prevent any part from being shaken, distorted, or bent;
Step 2. Use an open-end wrench to prevent the main connector from rotating;
Step 3. Use another wrench to loosen the screw on the connector.
Step 4. Loosen the screw by hand until the connection is completely broken.
Step 5. Separate two connectors by pulling them apart in parallel.
4) Use of the torque wrench
The torque wrench should be used as indicated in Figure 2.6. Please pay attention to the following points
when using the torque wrench:
Confirm that the torque of the torque wrench is set correctly before use;
Ensure that the angle between the torque wrench and the other wrench (used to support the
connector or cable) is less than 90obefore applying a force;
Gently grasp the end of the torque wrench handle and apply a force in the direction perpendicular to
the handle until the breakout torque of the wrench is reached.
Fig. 2.6 Use of Torque Wrench
5) Use and preservation of connectors
1) Protect the connectors with a protective sheath when not used;
2) Do not place the connectors, tools, etc. in a same box, which is the most common cause leading to
connector damage;
3) Keep the connector and analyzer at the same temperature. If the connector is held by hand or
cleaned with compressed air, the temperature will be significantly changed. The connector can be
used for calibration only after its temperature is stabilized;
4) Do not touch the joint surface of the connector because it is difficult to remove skin oil and dust
particles from the joint surface;
5) Do not place the contact surface of the connector downwards onto a hard surface; otherwise, the
electroplated layer and joint surface of the connector may be damaged.

6) Wear an anti-static wrist strap and work on a grounded conductive workbench mat to protect the
analyzer and connector against electrostatic discharge.
6) Cleaning of connectors
It is necessary to wear an anti-static wrist strap when cleaning the connectors as per the following steps:
1) Use clean low-pressure air to remove the loose particles on the thread and joint surface of the
connector and check the connectors thoroughly. If further cleaning is required, proceed as follows;
2) Wet (but not soak) a lint-free cotton swab with isopropyl alcohol;
3) Use a cotton swab to remove dirt and debris from the joint surface and thread of the connector.
When cleaning the inner surface, be careful not to apply an external force to the central inner
conductor or leave the cotton swab fibers on the central conductor of the connector;
4) Evaporate the alcohol and then blow the surface clean with compressed air;
5) Check the connectors to confirm that they are free of particles and residues;
6) If the connector still has visible defects after cleaning, it indicates that the connector may be
damaged. Never use a damaged connector, and confirm the causes of damage before
measurement and connection.
7) Use of adapter
When the measuring port of analyzer is different from the type of connector used, an adapter must be
adopted for measurement connection. In addition, even if the measurement port of the analyzer is the
same as the type of connector for the port of tested part, it is also a good idea to use an adapter. Under
these two conditions, the measuring port can be protected, thus extending its service life and reducing
the maintenance cost. Before connecting the adapter to the measuring port of analyzer, it should be
carefully checked and cleaned. A high-quality adapter should be used to reduce the impact of mismatch
on the measurement accuracy.
8) Joint surface of connector
An important concept in microwave measurement is the reference surface for all measurement. In the
case of calibration, the reference surface is defined as the surface on which the measuring port and the
calibration standard are jointed. Proper connection and calibration depend on whether the connectors
can be completely and straightly contact with each other at each point of the joint surface, so as to
ensure minimum power standing-wave ratio, achieve the minimum power loss, and ensure the
measurement accuracy.
