Audio can be digitally recorded and listened to via the normal telephone network. A large number of channels can be monitored, with a scan rate in excess of 2,000 channels per second. The frequencies monitored and configuration changes can be accessed by dial up modem.
Results are also available by remote transfer.
This approach provides a cost-effective monitoring solution for routine tasks and is easily adapted for more specialised jobs. A library of antenna factors and feeder characteristics are available within the unit which result in field strength statistics being directly stored on disk. This information is invaluable for future planning and frequency management. A purpose built monitoring vehicle is available for spectrum surveillance between 9 kHz and 18 GHz. The vehicle has been optimised for radio spectrum monitoring and is completely self-contained.
