Use an attenuator between the DUT and the power sensor when
measuring power levels that are higher than +20 dBm. The attenuator
value can be subtracted from the measurement using the Offset feature,

A sequence of status lights are displayed on the base of the power sensor,
when the FieldFox is in Power Meter (LAN Sensor) mode.
