Endurance Test System for Radio Car Key

A fully automated test system for remote keys. With this test the customer can perform durability tests for up to EIGHT different DUTs simultaneously in a climate chamber and at different frequency ranges.

Highlights

  • Possibility of testing up to eight remote keys in the round clock table
  • AM or FM modulated signal transmission
  • Frequency range: 315 MHz to 2,7 GHz
  • Trigger-controlled measurement of transmitting power and frequency with PXI-based RF-test system
  • Button actuation through integrated force- / path-controlled XYZ axis system
  • Testing in a RF-tight climate chamber
  • Temperature range: -40°C ... +85°C at 10% ... 98% RF
  • Mixed-Mode Operation of different key types in a durability test
  • Automatic control of climate parameters (temperature, humidity) in correlation to the test sequencer
  • Development of a customized operator interface
  • Automatic recording of the result data for each DUT

Advantages

  • Highly Scalable architecture that enables the rapid implementation of customer-specific requirements
  • Modular concept
  • Improved error simulation configurations
  • Full configurable by software and hardware based board processors
  • Reduces lead times and overall increase in test coverage within a given time frame
  • 24/7 operating times
  • Real time compatibility

Software

  • NI TestStand: Sequencer, Editor, Debugger
  • NI LabVIEW: Test Step libraries
  • KT-OP: Operator interface, Debugging
  • KT-Project: Test Step library, Functional Test
  • KT-Environment Server: Climate Chamber controller

 

With this durability test system, the end user received a reasonably priced system for continuous testing of up to eight different remote key/radio transmitters simultaneously, in all currently used frequency ranges.

The actuators integrated in the climate chamber make this system extremely compact while the PXI-based RF-measurement system has several analysis capabilities, necessary in today's and future testing; all these features secure the customers investment.
