Automotive RF Design Verfication Test System
The system is used for design verification of RF assemblies. By using similar measurement technology and test software as in the production testers, parts of the test procedures developed in development can be reused in production. The DUTs are tested in RF-tight shield boxes and contacted via original plugs. The shield boxes are connected via N-connectors and other typical laboratory contacts. This allows test setups to be easily modified and individual signal paths to be separated.
For switching the signals, LXinstruments has implemented two 19-inch plug-in modules that feature excellent reproducibility of the switched signal paths through the use of high-quality RF relays and semi-rigid cabling. The system has 24 stimulus and 24 response paths. Phantom power levels can be applied to all response paths via a power supply matrix and BiasTs.
Special attention was paid to a low noise level in the rack. The system is therefore supplied via special line filters, and linearly regulated power supplies are used to supply the auxiliary voltages.
