Features

Automatic measurement of electric field intensity while the car running at high speed.

Electric field strength such as AM radio, FM radio, business radio (police, firefighting, disaster prevention and etc.) and VICS can be measured automatically while installing in the car and running at high speed.
Multiple frequency bands selected from AM radio (14 ch max.) / FM radio (14 ch max.) / business radio (1 ch) / VICS (1 ch) can be measured at once.
*The minimum measurement interval depends on the number of selected frequency bands as follows.
When traveling 72 km/h : 1 band measurement : 8 meters, 2 bands measurement : 16 meters, 3 bands measurement：24 meters

Display graph in real time

During the measurement, it’s possible to display a line graph of electric field strength in real time on the PC screen.

Linked with Google Maps

By linking with the Google map after measuring, the measured electric field strength can be displayed on the map. However, in case GPS option is installed.

It can be used for application other than radio wave measurement.

As the handheld spectrum analyzer MSA500 series is used for electric field strength measurement, it can be used for application other than radio wave measurement.
(Maximum measuring frequency : 3.3GHz@MSA538, 8.5GHz@MSA558)

Software

Setting & measurement screen

1. Select measurement conditions setting from automatic or manual.

• Automatic
  The optimum setting values for measuring 14ch of AM radio, 14ch of FM radio and 1ch selected from business radio or VICS are automatically set.
• Manual
  The setting of center frequency, frequency span and reference level can be freely performed.

2. Start measurement with individual or batch start button.

• Individual
  1ch or multiple channels selected are measured individually.
• Batch
  All of selected channels are measured at a time.

Measurement result

A line graph of electric field strength is displayed in real time.

Map display function (when GPS option is installed)

By linking measurement data with Google map, the electric field strength can be displayed on the map. Also, the travel distance is accurate as it is interpolated by the vehicle speed pulse.
The color-coded point ● for each electric field strength is displayed on the map, so that you can see at a glance which wave of which route is strong or weak.
