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 on the receive path. To maintain the quality of a microwave link, it is critical
to keep the cable and antenna systems in good working condition. FieldFox is uniquely
qualiied to provide all the necessary measurements to troubleshoot and maintain these
systems.
Measurements:
– Insertion loss (2-port, when both ends are accessible) and cable loss (1-port, when
only a single port is easily accessible)
– Insertion loss or cable loss characterizes the loss of a jumper cable, feeder cable,
diplexer, or gain of a tower-mounted ampliier (TMA). Also, FieldFox’s ERTA option,
described on page 11, is useful for measuring long lossy in-situ cables.
Return loss and DTF display
– Return loss or VSWR
– Return loss / VSWR is the single most important parameter to measure and verify
a cable and antenna system. This measurement relects the power transfer
eficiency of a given system.
– Distance-to-fault (DTF) and time-domain relectometry (TDR)
– DTF helps users determine the location of discontinuities in feeder lines. TDR
helps users determine the nature of the discontinuities, for example, a short,
open, or water ingress.
With FieldFox, users can make both RL and DTF measurements at the same time. This
helps technicians correlate overall system degradation with speciic faults in the cable
and antenna system. The built-in cable editor allows users to edit existing cable types
on-site, and save them as new cable types with user deined names.
Filter insertion loss display
Measure both DTF and TDR in single sweep
Additionally, FieldFox’s TDR complements RL and DTF measurements. TDR measures
impedance changes along the cable and helps identify speciic faults, while 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.
Gain insight into faults with TDR measurements

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 measurements without having to connect/disconnect additional calibration
devices.
Hassle-free calibration in the ield with the industry’s irst and only
QuickCal
FieldFox is the industry’s irst and only handheld network analyzer with a built-in calibration
capability that allows you to calibrate the network analyzer without carrying a calibration
kit (cal kit) into the ield.
Step 1. FieldFox’s QuickCal allows you to
perform calibrations without carrying a cal
kit
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.
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
Step 2
For users who wish to use traditional mechanical calibration kits, FieldFox supports most
HP/Agilent/Keysight cal kits, and also allows you to deine 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.
Step 3

Spectrum Analyzer
Spectrum analyzer
In microwave, radar, and satellite communications, and commercial microwave backhaul,
engineers are responsible not only for hardware installation and maintenance, but also
over-the-air signal quality. They need to regularly monitor for rogue signals and perform
signal surveillance.
FieldFox’s spectrum analyzer is optimized to excel in the dynamic spectral environment
seen commonly in the ield. In the ield, users 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).
Monitor the spectrum using the FieldFox
analyzers
FieldFox’s superior dynamic range (TOI > +15 dBm), close in phase noise (—111 dBc/Hz at
10 kHz), 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 –
InstAlign
With FieldFox InstAlign, internal amplitude alignments occur automatically as the environmental conditions change, without any user intervention. This provides unprecedented amplitude accuracy up to ± 0.5 dB for spectrum analysis and power measurements.
Better yet, FieldFox provides this accuracy immediately upon instrument turn on – no
warm up required.
Spectrum analyzer time gating
FieldFox’s time gating is designed for engineers testing the pulse characteristics of their
radar systems. FieldFox’s gated FFT time gating allows for signals with pulse widths as
narrow as 8 μs to be measured. Triggering functions such as burst trigger and pre-trigger delay further ease pulse signal measurements.
IF signal output
FieldFox provides a spectrum analyzer IF output with 25 MHz bandwidth for use as a
frequency down-converter, and to perform wideband signal analysis.
Analyze pulsed-RF signals using the
spectrum analyzer time gating option

Spectrum Analyzer (continued)
Field strength measurements
To characterize the electric and magnetic ields, 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 complimentary Data Link software.
Interference analyzer
Interference can be internal or external, uplink or downlink, and has a direct impact on
the Quality of Service 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. Signal traces can be
recorded into internal memory or external lash memory devices, and the saved traces
can be played back for ofline processing. It has excellent dynamic range with very fast
sweep times under narrow resolution bandwidths (RBWs).
Use the internal microwave signal source
for transponder testing
Independent signal source
FieldFox has a built-in independent signal source, with a frequency range of 30 kHz to
26.5 GHz. 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, shielding effectiveness, and
frequency offset device veriication.
Extended range transmission analysis (ERTA)
Waterfall display makes interference hunting easier
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 ield. 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 coniguration can be used to make cable loss measurements
with accuracy of ± 0.7 dB.
Measure long lossy cables using ERTA

Vector Network Analyzer
Vector network analyzer
FieldFox’s Option 210 provides vector transmission and relection measurement (T/R), or
S11 and S21, with magnitude and phase. Adding Option 211 (full 2-port S-parameters)
brings new levels of accuracy and convenience for testing microwave components.
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. The full 2-port calibration gives you the best measurement accuracy
possible.
FieldFox’s four independent, sensitive receivers provide 94 dB of dynamic
range for measurement of high rejection, narrowband devices such as
cavity ilters. 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.

Vector Network Analyzer (continued)
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 coeicients 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.
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 ield maintenance and troubleshooting, as they provide good measurement
results at lower costs.
Time domain measurements provide insight
into the device under test
Vector voltmeter
Using FieldFox’s vector voltmeter (VVM), the phase shift and electrical length of a device
can be measured. 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.
FieldFox offers all the key functionalities of the HP 8508A, in a handheld form factor, and
without the need for the source/bridge/accessories required with HP 8508A.
Vector voltmeter used for cable trimming
Mixed-mode S-parameters
With FieldFox, you can measure the common and differential mode relections 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.

Built-in power meter
By leveraging InstAlign technology, FieldFox is able to make very accurate channel power
measurements. The channel bandwidth can be set wide to simulate average power meter
measurements. This measurement function provides the lexibility to make user deinable
channel power measurements with accuracy up to ± 0.5 dB.
USB power sensor support
FieldFox can connect with the Keysight USB power sensors to make microwave power
measurements. Using USB peak power sensors, users can measure both the average and
the peak power of a modulated signal.
Easily measure power levels using the builtin channel power meter
USB power measurements versus frequency
In addition to power measurements at a single CW frequency, users 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 positive.
This capability is useful for characterization of the scalar transmission response of devices such as mixers and converters. The FieldFox source stimulates the DUT and the power
sensor is used as the measurement receiver.

USB power sensor
Use FieldFox to characterize pulses
Pulse measurements
FieldFox’s pulse measurement option allows users to eficiently characterize pulsedRF signals such as those used in radar and electronic warfare systems, leveraging the
Keysight USB peak power sensors (available in 18 and 40 GHz models). Measurements
include peak power, peak to average ratio, and pulse proile parameters such as rise
time, fall time and pulse repetition frequency.

latitude, longitude, and elevation – can be displayed and saved in data iles. In addition
to location information, the GPS provides an accurate frequency reference to improve
accuracy.
Use the complimentary Data Link software
to generate reports
Built-in variable voltage DC bias
FieldFox has a built-in variable voltage DC bias source. The source provides 1 to 32 VDC
with maximum current of 650 mA and 8 W maximum power.
The DC bias source can provide DC power to ampliiers under test and bias tower
mounted ampliiers (TMA) when engineers need to sweep through the TMA to reach the
antenna (bias-tees available separately).
