How we implement solutions…

Turn-key solutions

The end-of-line test is the last step in the production chain. The findings of the EOL test can be used to improve the process quality in upstream production steps, if appropriate data records and data analyzes are carried out. A meaningful functional test, therefore, apart from the good/bad selection mainly makes an evaluation of statistical data and trends.

In our solutions we fundamentally consider

  • Accuracy of measurements
  • Stability of measurements
  • Speed optimization for highest throughput

We create high-quality solutions for our customers based on our own hardware concepts. We use suitable and common instruments on the market and integrate them into our solutions. Standard interfaces such as GPIB, PXI, LXI, USB, RS232 but also special interfaces are used. In our Tecap Software Platform, all devices are integrated and can be used on a high-level via the user interface.


Test of a Keyless Entry DCS ECU

Short description

A global supplier for the automotive industry needs to test a door controller with keyless entry functionality.

Kommunikation Keyless Entry

The ECU sends on 433 MHz or 426 MHz. Important while analyzing the signal is the frequency modulation gfsk and encryption. Additionally the transmitted message is manchester encoded. The received and transmitted signals are checked.

The antenna in the RF chamber is calibrated by a golden device.

Application adapter

The DUT is connected with the test rack by a hardware interface. The test rack has 18 slots; six are used for the application. The application is controled by the test rack bus and the DUT is connected to the internal tester instruments. Additionally the test rack contains signal conditioning cards between the PXI instrumentation and the DUT.


Platform is MTQ Hilerion

ECU for keyless entry and another different ECU – application on one platform

Applications based on the test extension rack TEX09 normally don't need too many slots. Therefore there are many slots for further applications available. For our automotive customer we could not only plug in the application for keyless entry but also place another application cost effectively into the same test rack.

The application is without additional changeover effort selectable by loading the appropriate test software package.

MTQ Project

The technological challenge has been the precise measurement of resister networks. The expected quality of the measurement result didn't allow to realize result calculation out of different values. Therefore MTQ developed a guarding concept for the 7 1/2 Digit DMM. That enabled these high accuracy measurements. The guard amplifier is connected via the system matrix to each of the relevant nodes.
