[Discontinued Product]ETC Automatic Inspection System ME8500

Automatic testing system developed for ETC’s OBE and RSU production or inspection lines.

Category: Tag:

Features

  • This inspection system was developed for ETC ‘s OBE and RSU production lines and inspection lines.
  • To be able of conducting radio system test and dynamic operation test (power profile test) automatically.
  • To be able of testing equipment itself and PCB mounting RF circuit.

  2. Deviation of antenna power
  3. Frequency deviation
  4. Strength of spurious emission
  5. Tolerance of occupied frequency bandwidth
  6. Carrier off leakage power
  7. Modulation factor
  8. Adjacent channel leakage power
  9. Transmission opening eye ratio

Troublesome work of relocation of cable connection is unnecessary

In a wireless system test, it is an extremely troublesome work to change connection of measuring instruments for each test item, as many measuring instruments are used.

With ETC automatic inspection system ME8500, measuring instruments and OBE or RSU signal are switched automatically by microwave signal switching equipment ME8530, signal switching and frequency counter ME8540 and connection and power source controller ME8580.

Furthermore, correction to insertion losses of components such as the microwave coaxial cable and switch is also executed, and more accurate test results can be obtained.
