Field Strength Measurements

To measure the strength of any signal transmitted through the air, an antenna
must be connected to the FieldFox. The Field Strength feature allows you to
enter the frequency response of the receiving antenna (the Antenna Factor)
and associated cabling, and then have amplitude corrections automatically
compensate the displayed trace for that response.
