Until recently, the task of mobile field strength logging required several pieces of conventional equipment interconnected into bulky and expensive systems.

WiNRADiO PFSL-3000 system provides an elegant, fully integrated solution, specifically designed for mobile "drive-by" signal coverage measurements, field strength mapping and related operations.

Portable Field Strength Logger

The PFSL-3000 system employs an integrated GPS receiver to display and store geographical co-ordinates of the measured signal. The logged data include time, date, latitude, longtitude and altitude.

The signal level can be measured in V, dBm or S-units, and field strength can be displayed in V/m or dBV/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, making the data easy to import into popular GIS packages for further processing. A provision also exists to specify the antenna factor of calibrated antennas for various frequencies, to achieve accurate measurements of field strength.

This system is enclosed in a ruggedized easily transported enclosure, which contains the control computer, the receiver and rechargeable battery all of which can be powered from a vehicle's 12V DC power outlet or from mains power. Leads to connect to mains and the vehicle power outlet are included. The enclosure features dual fans for cooling and built-in fuses protect system components. The GPS, radio receiver and power connectors are conveniently located in a recess on the side of the enclosure and can be accessed with the lid closed.

An integrated LED display shows the built-in battery's power reserve at the press of a button.

These systems are currently in use by major emergency service providers, communications providers and testing authorities world wide.


WiNRADiO 3000-Series receivers are at the heart of the PFSL-3000 systems, making it possible to achieve the necessary high level of integration. The receivers are designed to operate in the harsh electromagnetic environment existing inside a computer-based system.
