Preparing for Initial Use of Your New FieldFox 11
Preparing for Initial Use of Your New FieldFox
Check the Shipment
When you receive your FieldFox, check the shipment according to the following
procedure:
1. Inspect the shipping container for damage. Signs of damage may include a
dented or torn shipping container or cushioning material that indicates signs of
unusual stress or compacting. If not damaged, save the packaging material in
case the FieldFox needs to be returned.
2. Carefully remove the contents from the shipping container, and verify that the
standard accessories and your ordered options are included in the shipment
according to the Box Contents List.
3. For any question or problems, refer to Contacting Keysight on page 2.
Meeting Power Requirements for the AC/DC Adapter
Voltage: 100 VAC to 250 VAC
Frequency: 50 Hz to 60 Hz
Current: 1.25 –0.56 A
The AC/DC adapter supplied with the analyzer is equipped with a three-wire power
cord, in accordance with international safety standards. The power cable appropriate
to the original product shipping location is included with the FieldFox.
Various AC power cables are available from Keysight that are unique to specific
geographic areas. You can order additional AC power cables that are correct for use
in different areas. For the power cord part number information please visit:

12 FieldFox User’s Guide
Install the Lithium-Ion Battery
Step
Notes
1. Open the battery door.
Push the button on the battery compartment door while sliding the door
outward.
2. Insert the battery.
The terminals end of the battery is inserted into the compartment.
3. Close the battery door.
Slide the battery compartment door upwards until it latches.
Battery Usage
When you receive your FieldFox, the lithium-ion battery is not installed, and it is
partially charged to approximately 40% to preserve battery life. A lithium-ion battery
has no memory effect, so it can be used partially charged, as shipped.
A fully charged battery will power your FieldFox for about four hours, so if you plan to
use it for this long, you should fully charge the battery.
NOTE The FieldFox will shut down to prevent the battery from discharging to a level that is
damaging. If this occurs, charge the battery either internally or externally.
Learn more about the lithium-ion battery on page 185.
Battery charge status is viewable:
In the upper-right corner of the screen.
On the Battery screen. To access the screen, select System, Service
Diagnostics, and Battery.
On the battery. Open the FieldFox battery compartment door to view the battery
LCD.

Preparing for Initial Use of Your New FieldFox 13
To conserve battery power:
Use Run/Hold to single-trigger a measurement when needed. Hold is shown on
the display.
Press System then Display then Brightness. Use the ▲|▼ arrows, the rotary
knob, or numeric keypad to adjust the brightness to dim the FieldFox display as
much as possible.
Briefly press the power button to switch to Stand By mode when the FieldFox is
not being used. Press again to restore power. All current settings are preserved.
NOTE When powered by the battery only, the FieldFox can stay in Stand By mode for a
maximum of four hours and then it powers off automatically. When the relative
battery charge drops about 20%, the FieldFox will power off to preserve the
remaining charge.
To recharge a battery:
Use ONLY a FieldFox charger to recharge a battery.
The battery can be fully charged while in the FieldFox in about 4 hours with the
FieldFox either ON or OFF.
It can be fully charged externally using the external battery charger (Opt 872) in
about 4 hours.
When the battery is removed, the FieldFox can still be powered by the AC/DC
adapter.
FieldFox ON/OFF Settings
To turn power ON, briefly press the power button. Boot-up takes about 1 minute.
To switch to Stand By mode (low battery drain), briefly press the power button. To
turn power ON, briefly press the power button. Power and settings are restored
instantly. See the Note above concerning Stand By mode.
To turn Power OFF (very low battery drain), press and hold the power button until
power is OFF - about 4 seconds. Data and instrument state are NOT automatically
saved when the FieldFox is powered OFF. Learn how to save data and instrument
state on page 162.
You can make a setting to automatically Power ON the FieldFox when a power
source is connected. Learn how on page 183.
Power button LED status
Solid green –Power is ON
Blinking green –FieldFox in Stand By mode
Blinking amber –Battery charging.
Blinking amber and green –Stand By mode and battery charging.
Not lit –Power is Off and battery is not charging.
FieldFox High-Temperature Protection
The following features prevent degradation or damage in the event of high internal
temperatures in the FieldFox.

14 FieldFox User’s Guide
NOTE Do NOT store the FieldFox in the softcase while powered ON or in Stand By mode.
How to monitor the internal FieldFox temperature:
Press System, then Service Diagnostics.
Then Internal Temperatures.
The temperature at which the following events occur is the average of the RF1,
RF2, SB1, SB2 temperatures. These temperatures come from internal sensors
embedded within FieldFox.
Temperature Control Mode
At approximately 73 °C, the FieldFox enters Temperature Control mode by reducing
display intensity and measurement speed. This should decrease the internal
temperature which preserves measurement accuracy and maintains the long-term
reliability of the FieldFox.
When entering Temperature Control mode, save your instrument state and data that
you want to keep.
When the temperature drops to approximately 71°C, normal operating settings are
restored.
NOTE Measurement speed specifications do NOT apply in Temperature Control Mode.
High-Temp Shutdown
In extreme situations, Temperature Control mode may not stop an increase in the
FieldFox internal temperature. At approximately 75°C, High-Temperature Shutdown
will engage and turn OFF the FieldFox.
Just prior to shutdown, the FieldFox will display a warning of imminent shut down.
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.
WARNING
Maximum Input Voltages and Power:
RF OUT Connector: ±50 VDC, +23 dBm RF
RF IN: ±50 VDC, +27 dBm RF
DC Input: 19 VDC, 4 ADC
Learn more about Maximum power and voltages in the FieldFox Data Sheet on
page 201.
NOTE 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.

CAT (Cable and Antenna Test) Mode
CAT Mode is typically used to test an entire transmission system, from the
transmitter to the antenna. This process is sometimes referred to as Line Sweeping.
CAT Mode is similar to NA (Network Analyzer) Mode. Learn more in the
Supplemental Online Help:
http://na.support.keysight.com/fieldfox/help/FieldFox.htm
CAT Mode Distance to Fault measurements are discussed on page 30.
