Sometimes customers like the ability to use the vacuum chamber as a multi-purpose probing solution for a variety of applications – open air and under vacuum. Basic I-V, C-V and HF measurements using coaxial, triaxial, kelvin and HF probe arms, cables and connectors are used for open air and low voltage applications. When vacuum is required, the chamber is cleaned and sealed and operated to vacuum levels as low as 10-6 torr. Similar basic measurements under vacuum can be made as well as high voltage up to 10 KV.
