In space product testing environment Test + Measurement support equipment with special features are needed. Devices under test (DUTs) in thermal vacuum chambers have to be connected with the test-equipment outside the chamber. Also satellites under test in vast vacuum test chambers need to be connected with RF-assemblies for testing. Outgassing requirements according to ESA-PSS-01-702 is a must. Contamination of the devices under test from solvents of plastic materials has to be avoided as they can lead to corrosion of the content of the thermal vacuum chamber.
