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.
2
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.
3
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.
4
On the N991xA or N995xA analyzers, order Options 233 and 210 to obtain a tracking generator with the spectrum analyzer. Option 220
is not available on the N 991xA or N995xA analyzers. Option 233 provides the spectrum analyzer capability and Option 210 the “tracking”
capability.

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 ERTA 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 microwave combination analyzers: N9913A, N9914A, N9915A, N9916A, N9917A,
N9918A, N9950A, N9951A, N9952A
- FieldFox microwave spectrum analyzers: N9935A, N9936A, N9937A, N9938A, N9960A,
N9961A, N9962A
- ERTA cannot use N9912A, N9923A, N9925A, N9926A, N9927A or N9928A
The two FieldFox units used in ERTA do not have to be the same model.
ERTA requires the following options on Combo FieldFox models (N9913A, N9914A, N9915A,
N9916A, N9917A, N9918A, N9950A, N9951A, N9952A):
- Option 210, VNA transmission/reflection
- Option 233, spectrum analyzer
ERTA requires the following options on SA FieldFox models (N9935A, N9936A, N9937A, N9938A,
N9960A, N9961A, N9962A)
- 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 pow er 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

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 elusiv e 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 different, 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.

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).
SA and Interference Analyzer
Options 233 and 236
Record and playback spectrum traces Yes Yes

Requires spectrum analyzer mode (Option 233 on combination models), internal preamplifier (Option
235) and DC bias variable voltage source (Option 309) as well as CPU2 processor. 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.
Requires spectrum analyzer mode (Option 233 on combination models). Recommend GPS receiver
(Option 307) and internal preamplifier (Option 235). Supported only on N995xA and N996xA models,
since phased array antenna operates at 28 GHz.
Array Antenna (360), OTA LTE (370), and OTA 5GTF (377). 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 OSM once location coordinates (latitude and longitude) and zoom
levels have been entered the Map Explorer menu. If using the l
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.

technologies Triaxial Isotropic Antenna model SDIA-6000 30 MHz to 6 GHz. EMF measurements are
supported with spectrum analyzer mode (Option 233 on combination models).
Recommend 32, 44 or 50 GHz FieldFox model (N995xA and N996xA) to support 5GTF FR2
frequency of 28 GHz. Requires spectrum analyzer mode (Option 233 on combination models). Also
recommend GPS receiver (Option 307) and internal preamplifier (Option 235). FieldFox models 26.5
GHz and below will require external mixer to down convert millimeter wave frequency to intermediate
frequency (IF). For Keysight direct sales, mixer is orderable as Keysight model N9910XM28-H2A. For
indirect sales, the mixer is orderable as OML Inc. model M28H2ADC-K, please see website
www.omlinc.com for more information or contact a Keysight representative. OML mixer RF input
interface is 2.92 mm (f).
Surveyor 4D software connected to FieldFox spectrum analyz er mode offers a versatile, truly
portable spectrum monitoring system that covers VLF to 50 GHz, including 5G millimeter wave
bands. The software runs on an external PC or tablet. FieldFox required options include spectrum
analyzer mode (Option 233 on combination models), preamplifier (Option 235) and built-in GPS
receiver (Option 307). Core Surveyor 4D software for Windows (Option N6820ES-114) is required to
run the Surveyor 4D software. Other Surveyor 4D software optional licenses that are supported
include basic modulation recognition application (N6820ES-MR1) and universal signal detection
(N6820ES-USD). Requires Surveyor 4D software version 4.3 or later (May 2019).

RTSA trace recordings can be recalled and played back in SA mode Spectrogram. This has the added benefit that the measurements are
shown ‘slower’, making it easier for the human eye to decipher the signal content.
