ETC / ITS Spot Electric Field Strength Measurement System ME9200C

This system measures the electric field strength distribution of ETC / ITS spots with operating waves or CW in a short time and create electric field strength graphs and map diagrams.This is an upgraded version of the conventional ME9200.※Only for Japanese domestic specifications.

  • Measurement with a cart is possible, and the price of the ETC measurement system (9 antennas) is inexpensive.
  • The electric field strength distribution of the roadside machine installed at the ETC gate of the highway is measured accurately in a short time by CW and operation wave.
  • As an option, the electric field strength measurement function of the ITS spot can be added.

System overview

When 9 antennas are attached to the cart type, the 3.2m wide lane can be measured twice.

Comparison with the conventional ME9200

  • ME9200
    Conventional type:ME9200

  • ME9200C
  • Comparison with the conventional ME9200
  • The integrated rear radio wave absorber reduces variations in electric field strength due to reflection.
  • Comparison with the conventional ME9200
  • Since the antenna unit can be directly attached to the antenna fixing bar, the measurement preparation man-hours are reduced.
