Maintenance
Calibration
The 2818A should be calibrated periodically to maintain accuracy. The frequency and method of
calibration can vary based on the customer's requirement. AE-TEGAM recommends annual
calibration of the 2818A for typical applications. AE-TEGAM maintains full capability to
calibrate these standards. Contact AE-TEGAM to discuss your specific needs or to set up a
return RMA to have your standard calibrated.
Care and Handling of Assemblies
To ensure accurate measurements and optimal performance of AE-TEGAM products, the
microwave coaxial cable assemblies used in system and test setups must be properly used and
maintained. Proper connections, routine inspection of all cables, and cleaning of the connectors
are extremely important procedures which can prolong the longevity and accuracy of equipment.
Cable Inspection
Routinely check external cables for signs of cracked insulation, dents, twists, flattening, signs of
jacket abrasion, or other signs of abuse. Wrinkles in the jacket indicate that the minimum bend
radius has been exceeded. Most often, this occurs near the marker tubes and connectors.
Also inspect the connector interfaces for the following:
•
Bent pins (male).
•
Bent or missing tines (female).
•
Worn or chipped plating.
•
Damaged or displaced dielectric inserts.
•
Thread damage.
•
Folded or mushroomed outer interface rims.
•
Mushroomed pin shoulders (male) or tine ends (female).
•
Score lines on pins and outer interface rims visible to the unaided eye.
•
Recessed or protruding pins.
It is advisable to clean the connectors prior to inspection to make subtle damage more apparent.
Inspect the connector interface for signs of debris.
Debris may be in the form of:
•
Plating chips or other metal particles.
•
Dust and other miscellaneous foreign particles
