Cyclical temperature stress tests
In satellite technology, traveling wave tubes are used as powerful and robust amplification systems for microwave signals. The requirements made of quality and reliability of the tube amplifiers are very high. In orbit their average service life, e.g. in geostationary satellites like Astra, is around 15-18 years.
As early as the preliminary stages, intense functional and stress testing takes place in order to guarantee interference free usage. Cyclical temperature stress tests make sure that signal amplification always remains inside the tolerance range, even with fluctuating external conditions between -40 °C and +90 °C. Extreme testing conditions make special demands of the technical equipment.
Very fast temperature changes and long testing cycles require that the constant temperature equipment performs to the maximum, and does so in continuous operation. LAUDA Integral XT process thermostats meet these requirements perfectly.
