Radio Microphone ICS-MIC3

The ICS-MIC3 radio microphone and its docking station MICS-MIC3LN are used for the automated testing of the vehicle’s infotainment components:

  • Loudspeaker
  • USB connectors
  • Auxiliary connectors
  • Hands-free kits (in conjunction with GSM tester)

The ICS-MIC3 is connected with the docking station by an IEEE 802.15.4 radio system.The docking station is equipped with a LAN connector which enables the docking station to be controlled by a superordinate diagnostic test system. The commands are transmitted to the radio microphone by IEEE 802.15.4 radio.An audio test signal which is modulated on a VHF carrier is emitted on the loudspeaker group under test. The ICS-MIC3 analyzes the speaker signal and sends the test results to the docking station via IEEE 802.15.4 radio which then transmits the results to the superordinate diagnostic test system.For generating a VHF test signal either a Mobile Signal Generator (MSG) or a stationary HF-generator is used.For testing USB/Auxiliary connections the ICS-MIC3 is connected to the sockets in the vehicle by means of two spiral cables. The spiral cables can be replaced without disassembling the device.

 

Application

  • Central system for testing infotainment components for installation and performance
  • Individual tests
  • Parallel end-of-line tests
  • Integrated tests as subsystem of a DSA electrics/electronics test system

Benefits

  • No additional components such as e.g. PC required. Control can be directly effected by a superordinate diagnostic test system.
  • In contrast to conventional radio microphone systems no transmission of audio data via UHF channel is necessary. So a UHF receiver and analysis PC can be dropped. No licensing of UHF channels required.
  • Any number of ICS-MIC3/MIC3LN systems can be operated simultaneously without conflicting interference.
  • IEEE 802.15.4 radio is globally available and license-free.
  • Objective and repeatable test results
