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 ever y 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, N995x A, or N992xA. The reflection measurements of return loss and VSWR are included with every N991xA,
N995xA, and N992x A. 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 capabilit y, you need Options 233 and 210. Option 233 provides the spectrum analyzer capability
and Option 210 the “tracking” capability.

FieldFox RF and Microwave (Combination) Analyzer FAQs (continued)
QuestionAnswer
10. What are the requirements for
Option 209?
Extended Range Transmission Analysis (ERTA) or Option 209 is a scalar measurement system based on the use of
two FieldFoxes. One FieldFox acts as the source and reference receiver, while the second FieldFox acts as the
measurement receiver. When different frequency models are used in an ERTA pair, the ERTA system frequency
range is limited to the lowest of the pair.
Required hardware
A. Two FieldFoxes. FieldFoxes can be any of these models:
ERTA requires the following options on SA FieldFoxes.
(N9935A, N9936A, N9937A, N9938A, N9960A, N9961A, N9962A)
– Option 220, tracking generator
11. What is included with
Option 355?
12. What is included with
Option 350?
13. How do I determine if my
FieldFox has CPU2 fast
processor?
Both FieldFoxes (the one used as the source, and the other used as the receiver) must have the options listed
above. The ERTA option (209) cannot be installed unless 210 and 233 are present on a combo analyzer, or 220 is
present on an SA analyzer.
With either the Combo or SA FieldFoxes, the following options are highly recommended:
– Option 235, preamplifier – this option increases the measurement dynamic range by increasing the received
signal power.
– Option 307, GPS receiver – this option increases the dynamic range by increasing the frequency accuracy
and permitting the use of a narrower RBW.
B. Power splitter, two-resistor model, Keysight 11667A, 11667B, or 11667C. Other power splitters can be used but the
specifications listed are based on the match and tracking performance of 11667A, 11667B, or 11667C. Three-resist-
er power splitters are not recommended.
C. N9910X-712, Trigger/Reference-in cable, SMA (m) to BNC(f), 1 m, quantity two
D. N9910X-713, Trigger/Reference-out cable, SMB (m) to BNC (m), 1 m, quantity two
E. LAN connection – For ERTA, the two FieldFoxes communicate via a LAN connection. For a direct connection, a
cross-over LAN cable is required. Alternately, both analyzers can be on a local area network.
Recommended accessory
F. N9910X-825, GPS Antenna
FieldFox analog demodulation has two parts: (1) Tune and listen, and (2) AM/FM metrics. Tune and listen is available
with the purchase of the spectrum analyzer option 233. AM/FM metrics becomes available when Option 355 is
purchased. AM/FM metrics provides the user with RF spectrum view, demodulated baseband signal waveform,
carrier power, frequency deviation, SINAD and more.
Real-time spectrum analyzer (RTSA) or Option 350 provides real-time measurements on a FieldFox. The FieldFox
must be equipped with spectrum analysis capability. The preamplifier option is recommended, as elusive signals
often have low power levels. The maximum real-time bandwidth for option 350 is 10 MHz. RTSA includes trace
recording and playback capabilities. It does not include a frequency-mask trigger (FMT).
All N995xA and N996xA analyzers include CPU2. On other FieldFox models, if the serial number starts with
MY5607/SG5607/US5607, then it has CPU2. If the serial number prefix is dif ferent, then the analyzer firmware
needs to be checked to see if the instrument has been upgraded with N9910HU-100/200/300/400 to have CPU2.

– Spectrum Analyzer mode (Option 233) does not include Trace Recording and Playback by default. To obtain
this capability in SA mode, Option 236 Interference Analyzer and Spectrogram needs to be purchased.
– RTSA mode (Option 350) does include Trace Recording and Playback by default in RTSA mode.
– Purchasing RTSA mode (Option 350) does not enable Trace Recording and Playback in SA mode (Option 233).

bandwidth
No warm-up time required
measurement is within a certain frequency channel or bandwidth,
to make an accurate measurement, the user needs to know the
exact center frequency and the signal’s bandwidth and set those
accurately.
The measurement point needs to be connected to FieldFox’s RF
input port. If a RF jumper cable is used, the user needs to account
for the loss of the cable with an offset value (can be entered into
the analyzer).

(1) The recommended GPS solution is to order:
– Option 307 - built-in GPS receiver
– A GPS antenna such as N9910X-825– Other GPS antennas can also be used– The GPS connector on the instrument is SMA (f)
(2) Alternatively, you can purchase a USB-based GPS receiver. You do not need to purchase any FieldFox options
for the USB-based GPS to work. However, the USB-based GPS only provides time and location data, and time
synchronization capability. It cannot be used to increase the frequency accuracy of the instrument.
The DC output has a SMB (m) connector. Recommend ordering N9910X Option 713 bias-tee power cable SMB (f)
to BNC (m).
The connector for the Ref/Trig In is SMA (f). Recommend ordering N9910X Option 712 Trig/Ref in SMA (m) to BNC

(1) Option 030 provides a license for FieldFox to allow remote control via an iOS device.
(2) Not supplied by user, but necessary for operation of Option 030 are:
– iOS device: iPad, iPhone, or iPod Touch with iOS 6.1 or higher with free FieldFox app
– A WiFi or 3G/4G network connection between FieldFox and iOS device
Option 330 or pulse measurements requires a Keysight USB peak power sensor. Visit
www.keysight.com/find/usbsensorsforfieldfox for a list of supported peak power sensors. Average power sensors
cannot be used with Option 330, only peak power sensors. The peak power sensor needs to be purchased
separately.

Analog gauge display and digital display, dBm and watts
Relative/absolute measurements, dB or %, minimum and maximum limits
Trace graph for pulse profiling with gating
Rise time, fall time, pulse width, pulse period, pulse repetition frequency
Option 208 added, you can make swept-frequency power measurements. You can plot source power, gain, and
receive power versus frequency. Additionally, the source frequency can be offset from the receiver frequency. The
power sensor needs to be purchased separately.

1. 209 is a system based on two FieldFoxes. See page 6, FAQ #10, for a detailed description of the system requirements.
2. On N9938A, Option 320 is only available as a sof tware upgrade if the spectrum analyzer is already equipped with Option 100, which is 3.5 mm connectors
on the test por t. Option 100 must have been ordered at the time of original purchase. It cannot be upgraded later.
3. Requires CPU2 fast processor. See page 6, FAQ #13.

1. Upgrades are not available for FieldFox analyzers with serial number prefix starting with MY5607/SG5607/US5607, as these analyzers already have the
improved hardware.
2. Please contact your local Keysight Ser vice Center for instructions on how and where to send the instrument, and how to order the factory upgrades.
FieldFox analyzers support most standard HP/Agilent/Keysight mechanical calibration kits and all Keysight USB ECal modules.
Custom calibration kits can be created and uploaded to FieldFox using Data Link software.
