Note: A/B and B/A measurements require an external source
9. 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 (2) FieldFox units. 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 system frequency range is limited to the lowest of the pair.
Required hardware
A. Two (2) FieldFox units. FieldFox units can be any of these models:
- FieldFox combination analyzers: N9913/14/15/16/17/18/50/51/52/53B
- FieldFox signal analyzers: N9933/34/35/36/37/38/60/61/62/63B
The two FieldFox units used in ERTA do not have to be the same model.
- ERTA requires the following options on Combo FieldFox models
(N9913/14/15/16/17/18/50/51/52/53B):
- Option 210, VNA transmission/reflection
- Option 233, spectrum analyzer
ERTA requires the following options on SA FieldFox models (N9933/34/35/36/37/38/60/61/62/63B)
- Option 220, tracking generator
Both FieldFox units (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 a SA analyzer.
With either the Combo or SA FieldFox units, 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-resistor 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 FieldFox units communicate via a LAN connection. For a
direct connection, a LAN cable is required. Or, both analyzers can be on a local area network.
Recommended accessory:
F. N9910X-825, GPS Antenna. Necessary if Option 307 is ordered.

Question
Answer
10. What is included with Option
355?
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.
11. What is included with Option
350?
Real-time spectrum analyzer (RTSA) or Option 350 provides real-time measurements. The
FieldFox must be equipped with spectrum analysis capability. The preamplifier option is
recommended, as elusive signals often have low power levels. The real-time bandwidth options
include 10 MHz (standard), 40 MHz (Option B04), or 120 MHz (Option B10). RTSA includes trace
recording and playback capabilities. It does not include a frequency-mask trigger (FMT).
12. Is Spectrum Analyzer Trace
Recording and Playback
standard or an option?
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).

13. What are the requirements for
Noise figure (NF) Option 356?
Requires spectrum analyzer mode (Option 233 on combination models), internal preamplifier
(Option 235) and DC bias variable voltage source (Option 309). An external noise source is also
required and FieldFox supports Keysight noise source models 346A/B/C/K40/K01. Also
recommended to improve accuracy is an external preamplifier Keysight models U7227A/C/F or
U7228A/C/F. Requires accessory item N9910X-713 BNC to SMB cable for DC bias variable
voltage source to noise source connection.
14. What is required for phased array
antenna support (Option 360)
and 5GTF over-the-air (OTA)
measurements (Option 377)?
Requires spectrum analyzer mode (Option 233 on combination models) and GPS receiver (Option
307). Highly recommend internal preamplifier (Option 235). N991x/3xB (x>5) models require
external mixer since phased array antenna and 5GTF operates at 28 GHz. See FAQ #16 for more
OML mixer information. No external mixer required for N995x/6xB models.
15. What is included with indoor and
outdoor mapping (Option 352)?
The FieldFox mapping function is available in the following modes: Channel Scanner (312),
Phased-Array Antenna (360), and OTA LTE (370), OTA 5G TF (377), OTA 5G NR (378). Mapping
is currently not available in SA or RTSA modes. Outdoor mapping requires the availability of GPS
(Option 307). Maps can be saved to the FieldFox internal memory, SD card or USB drive. Using a
direct wired LAN connection, FieldFox will automatically access OpenStreetMap (OSM) once
location coordinates (latitude and longitude) and zoom levels have been entered the Map Explorer
menu. If using the l FieldFox Map Support Tool , OSM map files can be downloaded to a .zip
file and imported to FieldFox internal memory. If the FieldFox GPS receiver is enabled and OSM
maps have been previously saved to FieldFox with those GPS coordinates, FieldFox can
automatically load the corresponding map to match the current GPS coordinates.
16. What is required for EMF
measurements (Option 358)?
Requires triaxial antenna. Supported antenna is AGOS advanced technologies Triaxial Isotropic
Antenna model SDIA-6000 30 MHz to 6 GHz. It can also be ordered as Keysight 85572A-006.
EMF measurements are supported with spectrum analyzer mode (Option 233 on combination
models) and OTA 5G NR (Option 378).

FAQs – Applicable to all FieldFox RF and Microwave Analyzers
Question
Answer
A. What USB power sensors work
with Option 302?
All Keysight U2000x Series USB power sensors are supported with FieldFox.
Visit: www.keysight.com/find/fieldfoxsupport for an up-to-date listing.
B. What is the difference between
USB power sensor (Option 302)
and built-in power meter (Option
310)?
Option 302
USB power sensor
Option 310
Built-in power meter (or channel power meter)
Description
Option 302 allows users to
connect a USB power
sensor to FieldFox's USB
port and make broadband
power measurements
Option 310 is a channelized power measurement
capability built into FieldFox analyzers. Maximum
bandwidth is 100 MHz.
External hardware
USB power sensor
required
None. Uses internal receiver.
Power measurement
Broadband diode detector
measures all frequencies
Tuned receiver, so measures frequencies within defined
channel bandwidth
Frequency range
Depends on USB sensor
Frequency range of the analyzer
Settings
Set CW frequency
Set CW frequency, set channel width/span
Power range
Depends on USB sensor
Depends on channel width and attenuator setting
Warm-up time
30 minutes to meet
accuracy specifications
No warm-up time required
Accuracy
Depends on USB sensor
InstAlign accuracy: ± 0.5 dB typical for a CW signal.
Since the 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.
Programmable
Yes, via SCPI
Yes, via SCPI
Physical connection
The power sensor can
easily be moved to the
measurement point, with a
USB cable connecting the
detector to FieldFox.
The measurement point needs to be connected to
FieldFox's RF input port. If an 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).
FieldFox source control
Yes, on/off, and nominal
power level control
No access to FieldFox's source from the built-in power
meter mode

Question
Answer
C. What do I need to get GPS
information?
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 connector for GPS antenna 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.
D. What is the connector for
Option 309, DC output?
The DC output has a SMB (m) connector. Recommend ordering N9910X Option 713 bias-tee power
cable SMB (f) to BNC (m).
E. What are the connectors for the
Reference/Trigger In and
Reference/ Trigger Out?
The connector for the Ref/Trig In is SMA (f). Recommend ordering N9910X Option 712 Trig/Ref in
SMA (m) to BNC (f) cable.
The connector for the Ref/Trig Out is SMB (m). Recommend ordering N9910X Option 713 bias-tee
power cable SMB (f) to BNC (m).
F. What is Option 030 remote
control capability?
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 Wi-Fi or 3G/4G network connection between FieldFox and iOS device
G. What USB sensor is required
for Option 330?
Option 330 or pulse measurements requires Option 302 and 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.
H. What measurement capabilities
are included with Option 330?
Average power, peak power, and peak to average ratio
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
I. What is included with Option
208?
Option 302, USB power sensor measurements, includes CW power measurements (one frequency at
a time). With 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.
