Abstract
Arrangement to test HF tightness of a junction between two adjacent parts including HF generator ( ), HF line that guides the signal over junction ( ), measuring device ( ) as well as a signal analyzer. HF line includes two waveguides ( ) that have inner conductors ( ) connected all the way through by a connection conductor ( ) and outer conductors ( ) interrupted and each connected with electrodes ( ). A capacitive coupling of the HF signal occurs on one side of the junction and a capacitive decoupling of the HF signal takes place on the other side. By comparing the measured transmission and/or reflection of the HF signal with a transmission or reflection characteristic for the junction, it can be determined if the junction is HF tight. This makes it possible to test HF shielded cases for HF tightness in a non-destructive manner and without interfering with the contents.
