ETC / ITS Spot Electric Field Strength Measurement System
ME9200
- The price is inexpensiveness
It is possible to measure by handcart or by in-vehicle, and the price of ETC measurement system (9 antennas) is inexpensive.
- the electric field strength measurement function of the ITS spot
Optionally, the electric field strength measurement function of the ITS spot can be added.
- Automatically measure while driving.
When measuring the plural roadside units on the main line, the measurement is automatically performed even while driving according to the positions of the measurement section and measurement conditions registered in advance if the automatic measurement mode is used.
Antenna
The standard type consists of 9 antennas and the lane of 3.2m width can be measured at two times. <Antenna interval 20cm> The number of antennas can be increased up to 17 units. In addition, using a single antenna, the transmission frequency and power of the roadside unit outputting CW can be measured.
Outside domensions:138(W)×30(D)×101(H)mm (excluding projections)
Frequency accuracy:±20ppm
Handcart
Since the speed sensor is equipped, the measurement distance is automatically calculated. When 17units of antennas are attached, the lane of 3.2 m width can be measured at one time. The ground height of antenna can be set to 1m or 2m.
Outside domensions:700(W)×1000(D)×350(H)mm (when folding)
Outside domensions:700(W)×1000(D)×900(H)mm (when assembled)
Control unit
The start switch and the switch to adjust position of roadside unit to zero point are equipped. When measuring by in-vehicle, the distance is calculated by taking in the vehicle speed pulse of the car. Power supply of 12 VDC is required.
Outside domensions:430(W)×450(D)×101(H)mm (excluding projections)
PC software
It controls the control unit and immediately displays the measured electric field strength as a graph or map diagram. The automatic measurement mode can be used to measure the electric field strength of the plural
roadside units on the main line. This means the labor saving because it’s possible to measure without operating at each point while traveling by registering the spots “kilo-post” of multiple measurement sections and the measurement conditions beforehand.
