Stability TVAC™ Microwave/RF Cable Assemblies

Description

Thermal Vacuum (TVAC) chambers are used by space component manufacturers to test components, sub-systems and even entire satellites under space-like conditions. It is essential that the T&M components, including cable assemblies, used to test the deviceunder-test (DUT) inside the chamber be specifically designed to accommodate the effects of pressure and temperature created within the TVAC chamber.

Outgassing is the process whereby varying temperature and vacuum conditions cause materials to release free volatiles, which can deposit on other components in a test system and cause significant contamination. StabilityTVAC™ assemblies use low outgassing materials which meet the requirements of ASTM E-595 with a TML less than 1% and CVCM less than 0.1%

Changes in vacuum conditions force air in and out of cable assemblies, which can cause damage if not properly accounted for. Standard connectors require a slower change in pressure or risk damage. StabilityTVAC™ uses vented connectors which allow air to escape much faster, thereby empowering cable assemblies to stabilize and be used with minimal delays, and tests to be performed using rapid pressurization/depressurization cycles.

Like most mechanical components, cable assemblies expand and contract when presented with varying temperatures, which can cause changes in performance and even a permanent degradation. StabilityTVAC™ cable assemblies are thermally conditioned, going through aging and stabilization to relieve mechanical stresses for reliable performance over temperature.
