ETC inspection system for OBE production ME8600

  • Photo:ETC inspection system for OBE production ME8600
    • This is a low cost version automatic test system developed for OBE (on Board Equipment) production lines.
    • It is also good for wireless system tests, protocol tests, dynamic operation tests and communication tests.

Features

  1. All the tests during production of OBE can be conducted.
    • Wireless system test (receiving sensitivity and burst BER measurement in options are included, and it is 12 items.)
    • Protocol test (basic operation test of ARIB)
    • Dynamic operation test
    • Communication test
  2. All the tests are conducted automatically.
  3. Set an OBE in the small-size shielding box ME8661A and click [Test start] on the host computer. All the test items are executed automatically without human intervention.

  4. Test results are printed on an inspection sheet.
  5. Test results are printed on an inspection sheet of the user 's specified format on termination of a test. The customer is requested to give us the specified format at the time of placement of an order. The expenses for creation of inspection sheets are included in the standard system price.

  6. More compact with rack accommodation.
  7. The equipment is accommodated in a rack of height 1080mm (including castors), except for the small-size shielding box ME8661A, host computer and printer.

  8. Low price
  9. Price reduction was materialized by development of RSU simulator in our company and also by narrowing wireless system test items to important ones only.

[*2]Selection of the signal source for signal transmission speed test.

One out of the following can be selected as the signal source for "signal transmission speed" test.

  1. "TxC" signal taken out of the OBE to be tested.
  2. Signal produced by waveform shaping after detection of output signal in the state where the output mode of the OBE to be tested is set at repeating of "0" and "1" ... There is a possibility of dispersion arising in measured values due to noise, if this signal source is used.

[*3]RxC and RxD for receiving sensitivity test

In a "receiving sensitivity" test it is necessary to take "RxC (receiving clock)" and "RxD (receiving data)" out of the OBE to be tested. If RxC and RxD cannot be taken out, a simple method to substitute the test with a communication test is available. Please contact us for such a method.

[*4]Connection of burst BER measurement

The method illustrated below using a circulator is the standard connection for burst BER measurement.
