Choose the measurement routing using the largest all types offer a long service life providing they are bend radii possible. Small bend radii may affect treated with the appropriate care and attention. electrical performance. Exceeding the specified Microwave cable assemblies are high precision limits during the measurement process could cause a system components and require proper handling in permanent degradation. order to ensure that measuring performance values are maintained. 7. Avoid twisting microwave cable assemblies. To achieve the maximum measuring performance the Torsion of this type of assembly can alter the relative following guidelines should be followed: diameters of cable layers and affects the electrical characteristics. Exceeding the limit of 10 per metre 1. Assemblies should remain in their original packa- during measuring process could cause a permanent ging for delivery and storage. Storage temperature degradation. should be between -50 C and +80 C and the rela- tive humidity should not exceed 85%. 8. Examine interfaces for damage and/or contami- nation before mating. 2. Carefully unpack assemblies before measure- ment. Avoid kinking cables when straightening from a coil or reel. 9. Discharge connectors before mating or ensure that they are connected to a suitable ground. 3. Ensure that the surroundings are clean and free of dust, dirt and any other particles that could enter 10. When mating connectors with a screwed inter- unsealed connector interfaces. face always hold the connector bodies and turn only the coupling nut. This avoids twisting the cable and ensures minimum wear on the connector pins. 4. Use protective caps to prevent contamination whenever connectors are unmated. 11. Do not exceed the torque specified. 5. Where interfaces are contaminated, particles can be removed with dry, oil-free compressed air. Please use eye-protection. Interfaces can be cleaned with dry cotton swabs. Do not use hard hand-tools or sol- vents. Do not blow into interfaces or use normal compressed-air.
