Key Measurements
Cableandantennaanalyzer
Fifty to sixty percent of cell site problems
are caused by faulty cables, connectors, and
antennas. Degraded feed lines cause poor
coverage, unnecessary handovers, paging
failures, and access failures on uplink. To
avoid service quality problems, it is critical to
keep cell sites’ cable and antenna systems
in good condition.
Use FieldFox to make return loss, VSWR,
insertion loss/transmission, one-port cable
loss, and distance-to-fault (DTF) measurements.
You can test antennas, cables, ilters, and
ampliiers with a single instrument.

ReturnlossandDTF
measurements
FieldFox can make both return loss and
distance-to-fault measurements at the same
time. This helps you correlate overall system
degradation with speciic faults in the cable
and antenna system.
The built-in cable editor allows you to edit
existing cable types on-site, and save them
as new cable types with user deined names.

FieldFox
Measurements in the field
without the need to manually
calibrate
Each instrument is CalReady at the RF Out
port, immediately following power-on or
preset. This means it’s already calibrated and
ready to make measurements such as oneport cable loss, VSWR, return loss, and DTF
measurements at the test port.
Industry’s first and only
QuickCal
The industry’s irst and only built-in calibration system allows you to calibrate the cable/
antenna tester without carrying a calibration
kit into the ield. As with any test instrument,
when you add an additional device to the test
port, such as a jumper cable or attenuator, you
need to calibrate using a calibration kit (cal kit).
QuickCal eliminates the hassle of carrying
and using a cal kit, plus provides worry-free
accuracy every time.
Broadband calibration
FieldFox allows you to make broadband
calibrations, which means the instrument is
calibrated over the maximum frequency span.
After a broadband calibration, you can change
the frequency range or number of points without recalibrating the instrument.

FieldFox
Built-in spectrum analyzer
Interference is a major source of cell site
problems. Interference can be internal or
external, and uplink or downlink. Downlink
interference reduces coverage, while uplink
interference causes access failure. Interference has a direct impact on the quality of
service of wireless communication services.
RF spectrum monitoring
aided by spectrogram
recording
FieldFox has an optional built-in spectrum
analyzer that covers frequency ranges from
5 kHz to 6 GHz. It provides a fast spectrum
scan to detect interference and RF burst
capture to measure intermittent signals. It
displays four traces at the same time, and
you can choose different detector modes.
Field strength measurements
Field strength characterization is a common
test performed by operators in the field.
To make accurate measurements, the gain
and loss of the antenna and cables need to
be accounted for. With FieldFox, antenna
factors and cable loss data can be loaded
using either the front panel or the Data Link
software.

Interference analyzer
FieldFox interference analyzer is designed
for identifying interference signals quickly
in the ield. It has the best dynamic range
on the market (96 dB) with very fast sweep
times under narrow resolution bandwidths
(RBWs).
FieldFox provides a spectrogram and waterfall display to detect intermittent interference
signals or monitor signals of interest for
longer periods of time. Signal traces can be
recorded into internal memory or external
lash memory devices, the saved traces can
be played back for ofline processing.
FieldFox also allows you to listen to
demodulated AM/FM signals to identify
signal types.

FieldFox
Independent signal source and
tracking generator
FieldFox has a built-in independent signal
source, with a frequency range of 2 MHz to
4/6 GHz. The signal source and spectrum
analyzer can be on at the same time. The
signal source can be tuned to any frequency, independent of the spectrum analyzer
frequency.
The signal source can be used to create a
test signal to measure coverage, antenna
isolation, antenna direction alignment, frequency offset device veriication, and long
cable loss measurement.
FieldFox’sindependentCWsignalsource,coupled,viewedin“NightVision”
display mode
FieldFox’s source can generate both a CW
signal and a swept frequency signal, similar
to a traditional tracking generator. This
feature is standard on FieldFox RF analyzers
with spectrum analyzer Options 230 or 231.
Channelpowermeter
With Option 311, FieldFox is able to make
channel power measurements (CPMs) easily, without the need for an external USB
power sensor. Users can set the center
frequency directly or select from a list of
pre-deined radio standards such as GSM
or LTE. Additionally, with CPM, the channel
bandwidth can be controlled, thereby reducing errors caused by out-of-band signals.

Limit lines simplify testing
Limit lines or masks can be used for quick
pass/fail testing of devices or frequency
spectrums. FieldFox allows you to deine
ixed and relative limit lines, for both the
RF spectrum traces and S-parameters. Additionally, with a single key press, you can
build a limit line table from a current trace,
and add offsets or margins to simplify your
testing process.

Network analyzer time domain
With the time domain Option, FieldFox computes the inverse Fourier transform of the
frequency-domain data to display relection
or transmission coeficients versus time.
Time domain gating can be used to remove
unwanted responses such as connector
mismatch or cable discontinuities, and the
results can be displayed in either time or
frequency domain. FieldFox’s time domain
function supports both low pass mode and
band pass mode, enabling users to measure
both broadband and frequency-selective
devices.
Usetimedomaingatingtoremoveunwantedresponses.Beforegating:
Traces 1 and 3, After gating: Traces 2 and 4.
Network analysis
S11, S11 phase, Smith chart and polar
display are available with Option 303 (Network analysis capability). To obtain S21or
insertion loss/gain, users need to order
Option 110 (transmission measurement),
in addition to Option 303.
For in-ixture measurements, use FieldFox’s
port extension or electrical delay capability to easily extend the reference plane to
the device interface to provide accurate
measurements. You can use the electrical
delay capability to measure deviation from
linear phase by removing the linear portion
of the phase delay.
DeviceinputimpedancedisplayedonaSmithchart
If you need to measure the magnitude and
phase of all four S-parameters, consider the
N9923A FieldFox RF VNA. Please refer to
Agilent FieldFox RF Vector Network Analyzer, literature part number 5990-5087EN.
The marker bandwidth/Q factor function simplifies filter testing and tuning.

power sensors to make average power measurements up to 40 GHz. Using USB peak power
sensors, users can measure both the average
and the peak power of a modulated signal.
Pulsemeasurements
FieldFox’s pulse measurement option allows users to eficiently characterize pulsed-RF signals
such as those used in radar and electronic
warfare systems, leveraging Agilent’s USB peak
power sensors (available in 18 and 40 GHz models). Measurements include peak power, peak
to average ratio, and pulse proiling.
Transmission measurement
Pulsemeasurement
FieldFox provides a 2-port transmission
measurement that measures insertion loss,
ampliier gain, ilter passband, and loss. It also
makes a S21 scalar measurement if Option 303
is enabled.
Vectorvoltmeter
Transmission measurement
Using FieldFox’s vector voltmeter (VVM), the
phase shift and electrical length of a device can
be measured.
By utilizing the “Zero” function, the phase and
electrical length of one device can be measured
relative to a “golden device”. View results on
the large display which can be seen as far as
ten feet away.
FieldFox offers much of the VVM functionality
of the popular HP/Agilent 8508A, in a handheld
portable form factor, and without the need for
the source/bridge/accessories required with
the 8508A.

Vectornetworkanalyzertimedomain(Option010)
Using time domain, data from transmission or relection measurements in the frequency domain are converted to the time domain. The
time-domain response shows the measured parameter value versus time.
Time stimulus modes
Low-pass step
This stimulus, similar to a traditional time domain relectometer (TDR) stimulus waveform, is
used to measure low-pass devices. The frequency-domain data should extend from DC
(extrapolated value) to a higher value.
Low-pass impulse
This stimulus is also used to measure low-pass devices.
Bandpass impulse
The bandpass impulse stimulates a pulsed RF signal and is used to measure the time-domain
response of band-limited devices.
Windows
The windowing function can be used to ilter the frequency-domain data and thereby reduce overshoot and ringing in the timedomain response.
Gating
The gating function can be used to selectively remove relection or transmission time-domain responses. In converting back to
the frequency domain the effects of the responses outside the gate are removed.

Independent signal source or tracking generator
The independent source or tracking generator is included with either spectrum analyzer option 230 or 231. The source can be used in
continuous wave (CW) or stimulus/response (S/R) mode. In CW mode, the source frequency is independent of the receiver frequency.
The source can be tuned to a frequency that is different from the receiver. In stimulus/response mode, the source operates the same
as a traditional tracking generator - the receiver tracks the source.

PowermetermeasurementwithUSBsensor(Option302)
Support for Agilent USB average and peak power sensors. Frequency and power range dependent on sensor.
List of supported sensors: http://www.agilent.com/ind/usbsensorsforieldfox
PulsemeasurementswithUSBpeakpowersensor(Option330)
FieldFox’s pulse measurement option can be used to characterize RF pulses such as those used in radar and electronic warfare systems.
Measurements are made using FieldFox and Agilent’s UBS peak power sensors.
Performance speciications such as frequency, dynamic range and minimum pulse width depend on the peak power sensor. Supported
peak power sensors: www.agilent.com/ind/usbsensorsforieldfox.
RemotecontrolcapabilitywithiPadoriPhone(Option030)
Users can now remotely monitor and control their FieldFox using their iOS device such as an iPad, iPhone, or iPod Touch. FieldFox’s
Remote Viewer iOS app emulates the front panel of the unit, so users can simply press any FieldFox key right from their iOS device,
including the hardkeys or softkeys.
With this technology, FieldFox can now be placed in areas where users do not wish to stay long due to extremely harsh or unsafe conditions. Additionally, if one technician or engineer has trouble making a measurement or determining the source of a problem, another
can step in to remotely troubleshoot and solve the problem, which helps minimize rework and multiple trips.
When the application is launched, users can access the FieldFox demo videos and technical literature such as user guides, application
notes, and datasheets. Accessing this information via the FieldFox app helps engineers and technicians in the ield quickly ind the
data they need to resolve issues as they arise. Such capabilities also make the app ideal for training and educational purposes.
The iOS device and FieldFox communicate via a WLAN or broadband data connection. Without Option 030, users can remotely view
the live display screen of their FieldFox, but cannot control the instrument.
