Intelligent Charging Cable: Test Strategy and Test Execution

Automotive Solutions

Over the years, we have acquired profound, specific expertise in a number of areas, especially with respect to RF assembly and antenna technology testing. To give an example, we have acted as general contractor for implementing a number of rotary indexing tables for testing and labelling antenna amplifiers. The implementation as a rotary table has a number of advantages, since all mounting and test processes, as well as the handling of defective parts, are interlocked and concatenated, thereby effectively eliminating possible error sources during these process steps.

RF-Antenna Communication Links Functional Test

LXinstruments GmbH

The application encompasses functional tests of very large quantities of automotive antenna amplifiers, plus parallelization of tests by implementing several test stations in a rotary indexing table. The DUTs are inserted manually and after final assembly, they are loaded into the rotary table; this requires manual triggering by the operator.

Automotive RF Design Verfication Test System

LXinstruments GmbH

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.

IVTS In-Vehicle Test Set

LXinstruments GmbH

The in-vehicle test set was developed to successively measure several active RF amplifiers installed in the vehicle as well as different antenna structures. It offers the possibility to connect 12 DUTs. The DUTs can be connected to an external spectrum analyser via a 1 to 12 RF multiplexer. Each DUT can be individually switched and supplied with an adjustable voltage via a bias-tee integrated in the system. The individual bias voltages and currents are recorded by the IVTS and can be called up on an interactive control panel or via Ethernet and SCPI commands. The complete system can be powered by rechargeable battery and can be operated either via Ethernet, fibre optics or WLAN.

System for Analyzing Door Handles

LXinstruments GmbH

In the production process of a vehicle door handle, the electrical functions of the component are to be tested. The mechanical testing of the operation of the door handle is performed by a PLC-controlled test system. In addition to the mechanical test, the electrical parameters: “serial data stream” and “impedance of the antenna” are to be analysed.
