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.
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.

Question
Answer
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
5G NR over-the-air (OTA)
measurements (Option 378)?
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, which can be ordered as Keysight 85571A-028 or directly from Anokiwave as
AWMF-0129, operates at 28 GHz. See FAQ #18 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 FDD/TDD (370/371), 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 or an Android device.
2. Not supplied by user, but necessary for operation of Option 030 are:
• iOS device with iOS 6.1 or higher, or an Android device, with free FieldFox app
• A Wi-Fi or 3G/4G network connection between FieldFox and iOS device or an Android 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.
