Brief description

In the satellite sector, components, subsystems and entire satellites must be qualified in a thermal vacuum (TVAC) before they can be used in space.

This increasingly requires highly accurate, reliable power measurements directly on the DUT, i.e. in a TVAC chamber. Power sensors must therefore not only function in a high vacuum but also be able to withstand certain temperature fluctuations. The R&S®NRP33SN-V TVAC-compliant power sensor is specially designed for these requirements. All components are baked in a vacuum chamber during the production process, so outgassing is reduced to a minimum. Venting holes in the housing ensure pressure equalization between the inside of the sensor and the environment.
