The Field Strength Logger option adds a calibrated signal strength and field strength meter and logger to WiNRADiO G313, G315, G31DDC, G33DDC and G39DDC receivers. It is useful wherever it is necessary to measure absolute signal or field strength levels, and store them in a file in user-definable time intervals.
For use in geographical signal coverage surveys, the Field Strength Logger employs a GPS receiver to display and store geographical co-ordinates of the measured signal.
The signal level can be displayed in µV, dBm or S-units, and field strength can be displayed in µV/m or dBµV/m.
Instantaneous, peak or average values can be shown, calculated over user-definable intervals.
The contents of the logs have a flexible format, defined by the user. A provision also exists to specify the antenna factor of calibrated antennas for various frequencies, to achieve accurate measurements of field strength.
