Test & Measurement


Electromagnetic field monitors

22 July 2015 Test & Measurement

From Narda Safety Test Solutions comes the AMB-8059, a wideband area monitor that monitors electromagnetic fields up to 7 GHz in conformance with the ITU-T Recommendation K.83.

The data can be accessed via Ethernet or GSM/UMTS and several monitors can be integrated into a wide area coverage monitoring system through EMF Observatory software.

Depending on the probes used, the units capture electric field strengths in the frequency range 100 kHz to 7 GHz. The lower frequency range from 10 Hz to 5 kHz is covered by probes for electric and magnetic fields. Each monitor is completely autonomous, thanks to power from solar cells, with a reserve of up to 80 days operation in darkness.

The area monitor stores the measurement data internally. This can then be accessed locally using Ethernet, USB or RS-232, or transferred to SD card, or remotely by transmission via a mobile modem. If required, the monitor also transmits its position as GPS coordinates along with the measurement data. The web-based EMF Observatory software automatically collects data, stores it on a server, generates reports and statistics, and reacts immediately to alarms such as when limit values are exceeded or to messages about the operating status of individual stations.
