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 Agilent 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 Agilent 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:
http://www.agilent.com/find/fieldfox

Preparing for Initial Use of Your New FieldFox 11
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 105.
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.

12 N9923A FieldFox User’s Guide
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. The LED is green. Boot-up
takes about 1 minute.
To switch to Stand By mode (low battery drain), briefly press the power
button. The LED is orange and blinks. 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. The LED is off.
Data and instrument state are NOT automatically saved when the FieldFox is
powered OFF. Learn how to save data and instrument state on page 86.
FieldFox High-Temperature Protection
The following features prevent degradation or damage in the event of high
internal temperatures in the FieldFox.
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.

Preparing for Initial Use of Your New FieldFox 13
Then Internal Temperatures.
The temperature at which the following events occur is the average of the RF1,
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:
Port 1 or Port 2 Connector: ±50 VDC,
+23 dBm RF
Exter Trig/Ref Connector: 5.5 VDC
DC Input: 19 VDC,
4 ADC
Power Sensor Input: +25 dBm (320 mW) average
+33 dBm peak (2 W) <10μs
+ 5 VDC
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.

About S-parameters
S-parameters (scattering parameters) are used to describe the way a device
modifies a signal. The FieldFox can measure four S-parameters. The syntax for
each parameter is described by the following:
S (out | in)
out = FieldFox receiver port
in = FieldFox source port
The FieldFox automatically switches the internal source and receivers to make
both forward and reverse measurements. Therefore, the FieldFox can measure
all four S-parameters with a single connection.
When the source comes from port 1, the measurement is said to be in the
forward direction.
When the source comes from port 2, the measurement is said to be in the reverse
direction, which requires Option 122.
S11 and S22 reflection measurements are used to measure the amount of
reflections off the corresponding DUT port. Low reflections means there is a
good impedance match between the source and DUT.
S21 and S12 transmission measurements are used to measure the loss or gain
through a DUT over a specified frequency range. Both ends of the DUT must be
connected to the FieldFox. The FieldFox signal source is transmitted out one of
the test port connectors, through the DUT, and into the other test port connector.
How to measure S-parameters
1. Press Preset then Preset
2. Press Measure 1 then choose from the following:
oS11 Reflection measurement at port 1.
oS21 Forward 2-port transmission measurement.
oS12 Reverse 2-port transmission measurement. Requires Opt 122.
oS22 Reflection measurement at port 2. Requires Opt 122.
OR select a multi-trace configuration. Learn more on page 21.
3. Press Freq/Dist then either Start and Stop or Center and Span to enter a
Frequency Range for the measurement.
4. Press BW 2then IFBW to select the IF Bandwidth for the measurement.
Narrower bandwidths require more time to sweep, but lowers trace noise.
