Care and handling instructions for HUBER + SUHNER microwave cables
HUBER + SUHNER microwave cable assemblies of
all types offer a long service life providing they aretreated with the appropriate care and attention.
Microwave cable assemblies are high precisionsystem components and require proper handling inorder to ensure that measuring performance values
are maintained.
To achieve the maximum measuring performance thefollowing guidelines should be followed:
1. Assemblies should remain in their original packaging for delivery and storage. Storage temperature
should be between -50 °C and +80 °C and the relative humidity should not exceed 85%.
2. Carefully unpack assemblies before measurement. Avoid kinking cables when straightening froma coil or reel.
3. Ensure that the surroundings are clean and freeof dust, dirt and any other particles that could enter
unsealed connector interfaces.
4. Use protective caps to prevent contamination
whenever connectors are unmated.

6. Choose the measurement routing using the largest
bend radii possible. Small bend radii may affectelectrical performance. Exceeding the specifiedlimits during the measurement process could cause apermanent degradation.
7. Avoid twisting microwave cable assemblies.
Torsion of this type of assembly can alter the relative
diameters of cable layers and affects the electricalcharacteristics. Exceeding the limit of 10° per metre
during measuring process could cause a permanentdegradation.
8. Examine interfaces for damage and/or contamination before mating.
9. Discharge connectors before mating or ensurethat they are connected to a suitable ground.
10. When mating connectors with a screwed interface always hold the connector bodies and turn only
the coupling nut. This avoids twisting the cable andensures minimum wear on the connector pins.
11. Do not exceed the torque specified.

The HUBER+SUHNER is certified
according to ISO 9001 and ISO 14001.

5. Where interfaces are contaminated, particles canbe removed with dry, oil-free compressed air. Please
use eye-protection. Interfaces can be cleaned withdry cotton swabs. Do not use hard hand-tools or solvents. Do not blow into interfaces or use normal
compressed-air.
