Signalbox Technology
OTP-based Test System for Railway and General Power Electronics Modules
Application Description
Power electronics assemblies often cannot be tested using conventional technology for their electrical performance. Due to the adaptability of the instrumentation, the OTP concept offers an ideal platform even beyond the space requirements of several control cabinets. In order to achieve high test flexibility with different assemblies, the system was equipped with three-phase AC sources and AC loads as well as a precise three-phase power meter. DC sources and loads with different current and voltage ranges cover the test of frequent DUT operating parameters. Time-dependent voltage or current signals can be stimulated by an arbitrary generator with power amplifier. General measurements such as current, voltage, frequency, resistance can be carried out flexibly at various test points using the matrix concept. An oscilloscope with RF multiplexer is available for high-frequency measurements such as residual ripple, switching processes, etc.
In order to be able to test DUTs with mechanically large dimensions, a worktable was supplied in which the contour of the Virginia Panel table was fully integrated. This means that even heavy DUTs can be easily integrated into the test adapter. The operator safety is guaranteed at all times thanks to specially integrated safety circuits and a positive touch protection on the test adapter. The correct functioning of the system can be checked at any time using a self-test adapter.
Customer specific Software
Special test steps for interactive operator guidance were implemented in LabVIEW.

Testing takes place at the following stations of the rotary table:
- Checks of connector colors and screw lengths
- Functional tests by means of RF transmission measurements, testing of diversity functions, et. al.
- Functional tests, including assessment of the 3-channel radio controlled central locking
- Laser labelling of the DUTs and readout of the labeled data matrix code
- Automatic extraction of DUTs that have failed the test by means of a pneumatic gripper, and disposal of these parts in a bad parts box
Special Features
LXinstruments serves as the general contractor for the entire automation technology. Currently, there are 4 identical rotary indexing tables in use at the customer site, plus a large number of individual test systems.
Customer-specific Software
The test stations were implemented as independent software instances with parallel processing. Communication between the test stations and the PLC controller takes place via serial communication, based on IEEE-1349. All tests are fully retraceable; the test data is stored on a central database server, based on the LXinstruments test database. The entire solution was developed based on the LXinstruments standard software architecture, with additional functions for communicating with the automation technology.

Design Verification
Automotive RF Design Verfication Test System
Application Description
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.

E-Mobility: Function, Safety and Performance Tests for Charging Cables and Wall Boxes
Intelligent Charging Cable: Test Strategy and Test Execution
Application Description
The ICCB takes over the safety and control functions that are otherwise integrated in the stationary charging station. This places increased demands on the function test in production.
Test strategy: Separate function tests for the “operating and control unit” module and the “power electronics”.
The test of combined assemblies usually includes separate pre-tests of the two assemblies as well as the EOL test after assembly. During the functional test of the electronics, the power supply is first checked and the test firmware is programmed. Furthermore, the “internal electronics”, voltages at test points, interfaces such as I2C, SPI, CAN... as well as radio interfaces such as WLAN, Bluetooth are tested.
As instruments for functional testing of the control modules are often used:
- DC voltage sources with current monitoring
- JTAG programming devices
- Test firmware and boundary-scan HW
- Multiplexer/matrices for switching the test points to the measuring instruments
- Multimeter/oscilloscope/counter
- Test interfaces for I2C, SPI, CAN
- Coupling antennas and RF power meters or corresponding remote stations
Frequently performed tests of power electronics:
- Safety or insulation test with HV (5 contacts network to 5 contacts vehicle as well as test RCD/FI protection)
- Communication test e.g. Powerline
- Performance test AC e.g. 3kW, 11kW, 22kW, 42KW and optional DC 10kW-100+ kW
Special Features
Use of automated actors with finger imitations for testing capacitive touch-displays.
