13 | Keysight | FieldFox Handheld Analyzers – Technical Overview
Cable and Antenna Analyzer
Fifty to sixty percent of microwave-link
equipment issues are related to cables,
antennas and connectors. Degraded
feeder lines cause poor coverage, link
failures, and reduced sensitivity in the
receive path. To maintain the quality of a
microwave link, it is critical to keep cable
and antenna systems in good working
condition. FieldFox is uniquely qualified to
provide all the necessary measurements to
troubleshoot and maintain these systems.
Insertion loss and cable loss
Insertion loss or cable loss characterizes
the loss of a jumper cable, feeder cable,
diplexer, or gain of a tower-mounted
amplifier (TMA). With FieldFox, you can
measure both the 1-port cable loss and
2-port insertion loss. Also, FieldFox’s ERTA
option, described on page 16, is useful for
measuring long, lossy in-situ cables.
Return loss/VSWR
Return loss (RL) or VSWR is the
single most important parameter used to
measure and verify a cable and antenna
system. This measurement reflects the
power transfer efficiency of a given
system.
Distance-to-fault (DTF) and
time-domain reflectometry (TDR)
DTF helps you determine the location
of discontinuities in feeder lines. TDR
helps you determine the nature of the
discontinuities, for example, short, open,
or water ingress.
With FieldFox, you can make RL and
DTF measurements at the same time.
This helps you correlate overall system
degradation with specific faults in the
cable and antenna system. The built-in
cable editor lets you edit existing cable
types onsite, and save them as new cable
types with user-defined names.
View return loss and DTF simultaneously
Measure both DTF and TDR in
single sweep
FieldFox’s TDR complements RL and DTF
measurements. TDR measures impedance
changes along the cable and helps identify
specific faults, RL exposes mismatch
issues, and DTF indicates faults and poor
connections. FieldFox is the only handheld
instrument that can measure both DTF
and TDR in a single sweep.
Characterize filter insertion loss
Gain insight into faults with TDR measurements
14 | Keysight | FieldFox Handheld Analyzers – Technical Overview
Cable and Antenna Analyzer (continued)
CalReady-calibrated at power
on and ready to go
Save time and get right to work with
FieldFox’s CalReady feature. With CalReady, the analyzer is already calibrated
and ready to make measurements such as
S11, S22, 1-port cable loss, and DTF/TDR
measurements without having to connect
and disconnect additional calibration
devices.
Hassle-free calibration in the
field with QuickCal
FieldFox comes with a built-in calibration
capability that allows you to calibrate
the network analyzer without carrying a
cal kit into the field. With any other test
instrument, when you add additional
devices to the test port, such as jumper
cables or adapters, you need to recalibrate
using a cal kit.
FieldFox’s QuickCal supports measurements such as insertion loss/gain, 1-port
cable loss, return loss, and DTF/TDR.
Note: N995xA does not support QuickCal.
Broadband calibration
FieldFox allows you to make broadband
calibrations, which means the instrument
is calibrated over the maximum frequency
range. After a broadband calibration,
you can change the frequency range or
number of points without recalibrating the
instrument. The calibration is interpolated,
and accuracy is maintained.
User cal kit support
Use FieldFox’s QuickCal capability and perform
calibrations without carrying a cal kit
For users who wish to use traditional
mechanical calibration kits, FieldFox
supports most Keysight/Agilent/HP
cal kits, and also allows you to define
your own custom calibration kits.
Fast and accurate calibration
with ECal
The FieldFox calibration engine supports
Keysight’s USB ECal modules. ECal
support reduces calibration time and the
need to make multiple connections during
testing, while also providing for greater
consistency between measurements. For
FieldFox users, that translates into fewer
human errors and increased accuracy.
Perform fast and accurate calibrations using ECal
15 | Keysight | FieldFox Handheld Analyzers – Technical Overview
Spectrum Analyzer
In microwave, radar, and satellite communications, and commercial microwave
backhaul, you may be responsible not only
for hardware installation and maintenance,
but also over-the-air signal quality.
You may also need to regularly monitor
unexpected signals and perform signal
surveillance.
FieldFox’s spectrum analyzer is
optimized to excel in a dynamic spectral
environment. You may face measurement
challenges such as the need to detect
a low-level signal under strong signal
conditions (requiring high dynamic range),
or close-in small interference signals
(requiring excellent phase noise).
FieldFox’s superior dynamic range
(TOI > +15 dBm), close in phase noise
(—111 dBc/Hz at 10 kHz offset), and fast
sweep time make these challenging tasks
easier. FieldFox’s spectrum analyzer also
provides a full power measurement suite
and complete trace and state control.
Unprecedented amplitude
accuracy without instrument
warm-up
With FieldFox’s InstAlign capability,
internal amplitude alignments occur
automatically as environmental conditions
change, without any user intervention.
This provides unprecedented amplitude
accuracy of ± 0.5 dB for spectrum analysis
and power measurements. Better yet,
FieldFox provides this accuracy
immediately upon instrument turn on—
no warm-up required.
Monitor frequency spectra up to 50 GHz with
FieldFox
Spectrum analyzer time gating
The testing of RF pulses is always
challenging because so many instrument
settings interact. With Option 238, gated
FFT with time gating, FieldFox behaves like
a spectrum analyzer and an oscilloscope.
This enables you to quickly detect pulses
in the time and frequency domains. A gate
time of 6 µs to 1.8 s enables simultaneous
examination of one or more pulses, or
pulse rise and fall times, revealing the
effects of spectrum growth due to various
pulse shapes. Functions such as video
trigger, external trigger and RF burst
ensure reliable pulse detection. Automatic
trigger-delay and bandwidth settings
enhance characterization of RF pulses.
Analyze pulsed RF signals using the time-gating
option
16 | Keysight | FieldFox Handheld Analyzers - Technical Overview
Real-time spectrum
analyzer (RTSA)
With the widespread increase of wireless
technologies in commercial and military
networks, the spectral environment is
filled with intentional and unintentional
interference.
The spectrum density view displays three
dimensional data on a two dimensional
display. It uses color to show the number
of times a frequency and amplitude point
is detected during a capture interval.
The interfering signals result in network
quality deterioration and communication-link breakdowns. Additionally, the
prevalent use of digital modulation and
burst-transmission methods have made
it difficult to reliably detect interference
sources.
This is an excellent way to understand and
visualize the spectral occupancy of the
frequency band. For example, with RTSA
you can detect a low-level signal in the
presence of a high power transmitter using
the spectrum density view.
This is where RTSA in FieldFox can help.
With the combination of a fast, overlapping FFT processing technique, gap-free
measurement, and a 10 MHz real-time
bandwidth, FieldFox is able to detect
signals as short as 12 µs with 100% POI
with full amplitude accuracy.
In some applications, detecting signals is
the critical factor, independent of amplitude accuracy. In such cases, FieldFox can
detect signals as short as 22 ns.
Density display with settable persistence
Finding an elusive signal can typically take
hours or days. With FieldFox’s recording
and playback, data can be saved for
further analysis offline at a later date.
With RTSA in FieldFox, you can now
eliminate the need for a separate,
dedicated instrument. When needed, just
shift to real-time capabilities in the same
unit with one key press.
Identify multiple types of signals in the same band
(Bluetooth and Wifi)
Multi-pulse detection with the density display
17 | Keysight | FieldFox Handheld Analyzers – Technical Overview
Spectrum Analyzer (continued)
Interference analyzer
Channel scanner
Interference can be internal or external,
uplink or downlink, and has a direct
impact on the quality of service (QoS)
of a communication network. FieldFox’s interference analyzer is designed to identify
interfering signals quickly. Spectrogram
and waterfall displays detect intermittent
signals or monitor signals over a period
of time. You can record signal traces into
internal memory or external flash memory
devices, and play back the saved traces
for offline processing. It has excellent
dynamic range.
Channel scanner allows users to make
multiple channel power measurements
simultaneously. It is used to verify
wireless network coverage, path loss
and potential interference issues. It also
can be used to measure primary carriers
and their intermodulated products. Each
instrument state can be a custom set of
frequencies with each frequency having a
unique integrating bandwidth. Users can
record and playback the data with data
logging. Using time interval logging along
with geotagging, files can be exported
to Google Earth for network coverage
analysis.
AM/FM analog demodulation
Using FieldFox’s analog demodulation,
users maintaining AM/FM radio transmitters can demodulate and characterize
AM and FM transmitters. They can tune
to the signal and listen to the audio tones
using FieldFox’s built-in speakers or a
headphone. They can also measure the
RF spectrum, the demodulated waveform
and AM/FM metrics such as carrier power,
modulation rate, and SINAD.
Waterfall display makes interference hunting easier
Characterize AM/FM signals using AM/FM demodulation
Scan up to 20 channel simultaneously with the
channel scanner option
18 | Keysight | FieldFox Handheld Analyzers - Technical Overview
Spectrum Analyzer (continued)
IF signal output
FieldFox provides a spectrum analyzer
IF output with 25 MHz bandwidth. This
enables use as a frequency downconverter
and digitize the signal using external test
equipment like real time scope, or VSA to
do deep signal analysis.
Field strength measurements
To characterize the electric and magnetic
fields, the gain and loss of the antenna
and cables must be accounted for. With
FieldFox, you can load antenna factors and
cable loss data using either the front panel
or the complimentary Data Link software.
Independent signal source
FieldFox has a built-in independent signal
source, with a frequency range of up to
50 GHz. The signal source can be tuned
to any frequency, independent of the
spectrum analyzer frequency. You can
use the signal source to create a test
signal to measure coverage, antenna
isolation, antenna direction alignment,
and shielding effectiveness, and to verify
frequency-offset devices.
Extended range transmission
analysis (ERTA)
Measuring long in-situ microwave cables
such as those on ships is a challenging
task, and requires instruments with high
dynamic range and fast measurement
speed. These measurements were traditionally done using benchtop scalar
analyzers, which are cumbersome to
operate in the field. Using FieldFox’s
ERTA, users can measure dynamic
ranges of 108 dB (at 6 GHz) or 77 dB
(at 26.5 GHz), with a portable analyzer
that requires no calibration and no
warm-up. ERTA uses two FieldFoxes,
one deployed at each end of the cable.
One FieldFox acts as a source, while
the other acts as a receiver. By taking
advantage of Keysight’s proprietary
InstAlign technique, this configuration
can be used to make cable loss measurements with accuracy of ± 0.7 dB.
Use the internal microwave signal source for
transponder testing
Measure long, lossy cables using ERTA
19 | Keysight | FieldFox Handheld Analyzers – Technical Overview
Vector Network Analyzer
FieldFox can be configured with VNA
transmission/reflection (T/R) capability
for S11 and S21 measurements, or with
full 2-port capability for measurements
of all four S-parameters and full 2-port
calibration.
With a full 2-port network analyzer, you
can measure the forward and reverse
characteristics of your component without
having to disconnect, turn around, and
reconnect it to the analyzer. Additionally,
the full 2-port calibration gives you the
best measurement accuracy possible.
Calibration
FieldFox’s guided Cal Wizard takes guessing out of calibration and allows you to
easily perform the following calibrations:
–– Full 2-port unknown thru
–– Full 2-port QSOLT
–– OSL, response, enhanced response
–– TRL, LRL, offset short
Simultaneously measure and view all four
S-parameters, with a single connection
FieldFox’s four independent, sensitive
receivers provide 94 dB of dynamic
range for measurement of high rejection,
narrowband devices such as cavity filters.
The receivers also enable full 2-port error
correction with the unknown thru method,
allowing users to measure non-insertable
devices accurately and easily.
FieldFox’s calibration engine is the same
engine that powers the well-respected
Keysight ENA and PNA network analyzers.
FieldFox leverages Keysight microwave
expertise to deliver consistent measurements with Keysight benchtop VNAs.
Use the marker bandwidth/Q factor function to
simplify filter testing and tuning
20 | Keysight | FieldFox Handheld Analyzers – Technical Overview
Vector Network Analyzer (continued)
Network analyzer time domain
Vector voltmeter
With the time-domain option, FieldFox
computes the inverse Fourier transform
of the frequency-domain data to display
reflection or transmission coefficients
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.
Using FieldFox’s vector voltmeter (VVM),
you can measure the phase shift and
electrical length of a device. You can
view results on the large display as far as
ten feet or three meters away. VVM also
provides ratio measurements of magnitude
and phase of two channels, A/B or B/A.
You can use this capability to verify the
magnitude and phase differences between
multiple signal paths such as in an antenna
or phased array.
Waveguide support
Waveguides are widely used to provide
transmission links between microwave
transmitters and antennas, as waveguides
have less loss than coax. Keysight
offers both high-performance and also
economical waveguide calibration kits.
The economical kits are ideal for field
maintenance and troubleshooting because
they provide good measurement results at
a lower cost.
Easily use waveguides with FieldFox
FieldFox offers all the key functionalities
of the HP 8508A in a handheld form factor,
and without the need for the source,
bridge and accessories required with the
8508A.
Mixed-mode S-parameters
With FieldFox, you can measure the common- and differential-mode reflections of
a device. Mixed-mode S-parameters are
also known as balanced measurements.
This measurement requires the full 2-port
VNA and 2-port cal functionality.
Simplify cable trimming with the vector voltmeter
capability
Characterized common and differential mode reflections with mixed-mode S-parameter measurements
21 | Keysight | FieldFox Handheld Analyzers – Technical Overview
USB power measurements
USB power sensor support
Pulse measurements
FieldFox can connect with Keysight USB
power sensors to make RF and microwave
power measurements. Using USB peak
power sensors, you can measure both
the average and the peak power of a
modulated signal.
FieldFox’s pulse measurement option
allows you to efficiently characterize
pulsed RF signals such as those used in
radar and electronic warfare systems,
leveraging the Keysight USB peak power
sensors. Measurements include peak
power, peak to average ratio, and pulse
profile parameters such as rise time, fall
time and pulse repetition frequency.
USB power measurements
versus frequency
Simplify power measurements with USB power
sensors
In addition to power measurements at a
single CW frequency, you can measure
power versus frequency - a swept measurement. FieldFox’s source frequency
can be set equal to the sensor/receiver
frequency, or with an offset. The frequency
of both the source and receiver are swept,
and the two track each other. The offset
frequency can be negative, zero, or

software provides data transfer, data
definition and report generation. You can
add markers and limit lines to traces,
and you can load cable files and antenna
factors using Data Link.
Remote control via LAN and
FieldFox programming
Built-in variable voltage DC bias
FieldFox has a built-in variable voltage
DC bias source. The DC bias source can
provide DC power to amplifiers under test

separately).
Built-in GPS
Control and view your FieldFox via your iPad
A built-in GPS receiver provides
geo-location tags to measurements.
The geo data—time, latitude, longitude,
and elevation—can be displayed and
saved in data files. In addition to location
information, the GPS provides an external
reference to improve FieldFox frequency
accuracy.
USB keyboard and mouse
support
Obtain geolocation data with the built-in GPS
capability
FieldFox supports use of USB keyboards
and mice to simplify the input of text such
as file names while working in the field.

Notes:
Base model means that the functionality listed is the primary function of that instrument. For example, on the N991xA or N995xA combo analyzers, cable and
antenna analysis is the standard function included with every N991xA or N995xA.
1. Option 305 is not available on the N993xA or N996xA. However, a subset of cable and antenna analyzer measurements, return loss and VSWR, is available
as Option 320.
2. Option 320 is not applicable to N991xA, N995xA, or N992xA. The reflection measurements of return loss and VSWR are included with every N991xA,
N995xA, and N992xA. So there is no need for an Option 320 on these analyzers.
3. On the N991xA or N995xA analyzers, order Options 233 and 210 to obtain a tracking generator with the spectrum analyzer. There is no Option 220 on the
N991xA or N995xA analyzers. To obtain tracking generator capability, you need Options 233 and 210. Option 233 provides the spectrum analyzer capability
and Option 210 the “tracking” capability.
