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.

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

Conventional type:ME9200

The integrated rear radio wave absorber reduces variations in electric field strength due to reflection.

Since the antenna unit can be directly attached to the antenna fixing bar, the measurement preparation man-hours are reduced.

Standard specifications


The standard is 9 pieces, and 3.2m wide lanes can be measured twice.≪Antenna spacing 20 cm≫.

  • External dimensions:195(W)×105(D)×300(H)mm(excluding protrusions)


Equipped with a speed sensor, the measured distance is calculated automatically.
With 9 antennas installed, 3.2m wide lanes can be measured twice.

  • External dimensions:700(W)×1000(D)×350(H)mm(when folded)
  • External dimensions:700(W)×1000(D)×900(H)mm(when assembled)

Control Unit

It has a start SW and a SW that adjusts the zero point at the roadside machine position.
Requires DC12V or AC100V power supply. An AC/DC converter is included as standard.

  • External dimensions:430(W)×450(D)×101(H)mm(excluding protrusions)

PC Software

It controls the control unit and immediately displays the measured electric field strength value in a graph or map diagram.

Electric field strength measurement example

The ME9200 software running on a PC controls the control unit to perform measurements, and automatically collects, analyzes, and displays data.

※Customization such as vihicle- mounted will be discussed separately.
※CW:Continuous Wave
