Preparing for Initial Use of Your New FieldFox

Avoid Overpowering the FieldFox

The FieldFox can be damaged with too much power or voltage applied.

Exceeding the maximum RF power levels shown below will cause an ADC Over

Range message to appear on the screen.

Maximum Input Voltages and Power:

– RF Output Connector: 50V DC, +23 dBm RF

– Ext Trig/Ref Connector: 5.5 V DC

DC Input: 19VDC, 4ADC, 60 Watts maximum when charging battery

Learn more about Maximum power and voltages in the FieldFox Data

Sheet. Refer to the C-Series FieldFox Data Sheet and

"Specifications/Data Sheet," on page

Very often, coaxial cables and antennas build up a static charge, which, if

allowed to discharge by connecting to the FieldFox, may damage the

instrument input circuitry. To avoid such damage, it is recommended to

dissipate any static charges by temporarily attaching a short to the cable

or antenna prior to attaching to the FieldFox.
