Automatic measurement of ETC electric field strength

It is possible to perform measurement and analysis automatically by merely running the measurement point.


The amount of information and diversity to be treated on highway are increasing owing to the wireless information technology every year. Not only the fee payment information at ETC toll gate, but also the various informations are treated with such systems as VICS, ITS spot and FF.

When the program measurement mode of an electric field strength measurement system ME9200 is used, the troublesome changes of such as antenna frequency and modulation type during travel are unnecessary.

That is, when the informations of antenna location, frequency and modulation type are inputted into a program file in advance, the measurement and analysis can be automatically performed during travel of a measurement point.
