Definitions
All specifications and characteristics apply over a 25 ±5 °C range (unless otherwise stated) and 90 minutes
after the instrument has been turned on.
Specification (spec.)
Warranted performance. Specifications include guardbands to account for the expected statistical
performance distribution, measurement uncertainties, and changes in performance due to environmental
conditions. The following conditions must be met:
-
FieldFox has been turned on at least 90 minutes
-
FieldFox is within its calibration cycle
-
Storage or operation at 25 ±5 °C range (unless otherwise stated)
Typical (typ.)
Expected performance of an average unit over a 20 °C to 30 °C temperature range after being at ambient
temperature for two hours, unless otherwise indicated; does not include guardbands. It is not covered by the
product warranty. The FieldFox must be within its calibration cycle.
Nominal (nom.)
A general, descriptive term or design parameter. It is not tested, and not covered by the product warranty.
Calibration
The process of measuring known standards to characterize an instruments systematic (repeatable) errors.
Corrected (residual)
Indicates performance after error correction (calibration). It is determined by the quality of calibration
standards and how well "known" they are, plus system repeatability, stability, and noise.
Uncorrected (raw)
Indicates instrument performance without error correction. The uncorrected performance affects the stability of
a calibration.

Time Domain
Using time domain, data from transmission or reflection measurements in the frequency domain are converted to the time
domain. The time-domain response shows the measured parameter value versus time.
Time stimulus modes
Low-pass step
Similar to a traditional time domain reflectometer (TDR) stimulus waveform, Low-pass step
is used to measure low-pass devices. The frequency-domain data should extend from DC
(extrapolated value) to a higher value.
Low-pass impulse
Also used to measure low-pass devices
Bandpass impulse
Stimulates a pulsed RF signal and is used to measure the time-domain response of bandlimited devices
Windowing
The windowing function is used to filter the frequency-domain data and thereby reduce overshoot and ringing in the timedomain response.
Gating
The gating function is used to selectively remove reflection or transmission time-domain responses. When converted back to
the frequency domain, the effects of the responses outside the gate are removed.

Tracking Generator or Independent Signal Source
The independent source or tracking generator is included with either spectrum analyzer option. The source can be used in
continuous wave (CW) or stimulus/response (S/R) mode. In CW mode, the source frequency is independent of the receiver
frequency. The source can be tuned to a frequency that is different from the receiver. In stimulus/response mode, the
source operates the same as a traditional tracking generator - the receiver tracks the source.

Radio Standards
With a Radio Standard applied, pre-defined frequency bands, channel numbers or Uplink / Downlink selections can be used
instead of manual frequency entry. The pre-defined FieldFox Radio Standards include bands such as W-CDMA, LTE, and GSM.

Power Sensor Measurements vs. Frequency
This feature allows the FieldFox source frequency to be set independently from the power sensor (receiver) frequency. With
frequency-offset using power sensor (FOPS), 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.
FOPS can be used to characterize the scalar transmission response of devices such as mixers and converters. This
frequency-offset capability is necessary for conversion loss/gain measurements on frequency-translating devices, since by
definition, the input and output frequencies of the DUT are different. The FieldFox source stimulates the DUT and the power
sensor is used as the measurement receiver.
Since power sensors are inherently broadband devices (not frequency-selective), the user should ensure that only the signal
of interest is present at the power sensor input and that all others signals are filtered appropriately.

Number of points

Combination of number of points and frequency step size limited by span.
Dwell time/point:

Source frequency span must be equal to receiver frequency span.
Receiver sweep direction: forward (default setting) or reverse.
For some DUTs, the output frequency may sweep in a reverse direction, as compared to the source frequency. The basic
relationships between the source, receiver and offset frequencies are shown in the table below. The FieldFox analyzer
includes an offset calculator that ensures a fast measurement setup.
Src sweep direction
Rx sweep direction
Frequency calculations
Forward f2rc > f1src
Forward f2rx > f1rx
Receiver frequency = Source frequency ± Offset
Forward f2src > f1src
Reverse f2rx < f1rx
Receiver frequency = Offset – Source frequency Offset > Source

Description
Measurements
Source power, gain/loss and receiver (Rx) power
Gain = Rx power / source power (memory). Source power (memory) is measured during
setup.
Output power
Refer to the test port output power typical data on page 5
Dynamic range
The dynamic range with FOPS is dependent on FieldFox’s output power and the power
sensor’s dynamic range. Supported USB power sensors:

Power Sensor Measurements vs. Frequency (continued)
Description
Measurements
Source power, gain/loss and receiver (Rx) power
Gain = Rx power / source power (memory). Source power (memory) is measured during
setup.
Output power
Refer to the test port output power typical data on page xx
Dynamic range
The dynamic range with FOPS is dependent on FieldFox’s output power and the power
sensor’s dynamic range. Supported USB power sensors:
www.keysight.com/find/fieldfoxsupport
The graph below shows a filter measurement using two different power sensors, the U2002A (-60 to +20 dBm) and the
U2021XA (-45 to +20 dBm).
While a filter is not commonly measured using FOPS, it is a useful device for demonstrating dynamic range.
For both measurements, the FieldFox source power was set to 0 dBm, the maximum available in the selected frequency
range of 150 to 450 MHz.
26
Pulse Measurements
The FieldFox pulse measurement option can be used to characterize RF pulses such as those used in radar and electronic
warfare systems. Measurements are made using FieldFox and Keysight's UBS peak power sensors.
Performance specifications such as frequency, dynamic range and minimum pulse width depend on the peak power sensor.

Remote Control Capability
Option 030 adds remote control capability to FieldFox analyzers, so that FieldFox can be controlled via an iOS device. The
FieldFox app, running on the iOS device, combined with Option 030 on the FieldFox analyzer provides full control of the
instrument from a remote location. The app emulates the front panel of FieldFox, so users can press the FieldFox hardkeys or
softkeys using their iPhone or iPad, and make measurements remotely.
-
iOS device requirements
iPhone, iPad, or iPod Touch
iOS of 6.1 or higher
A WiFi or 3G/4G connection
The FieldFox app communicates with FieldFox via a network connection, so both the iOS device and FieldFox need to be on a
network where both devices can reach the other. For example, a company intranet or a site installation using a wireless
router. FieldFox can directly be connected to a LAN cable, or if wired LAN is not available, a user supplied wireless router can
be configured to work with FieldFox.
FieldFox app without Option 030
The FieldFox app can be installed on an iOS device independent of the presence of Option 030 on the analyzer. Without
Option 030, users can view the live display screen of their FieldFox remotely, but cannot control the instrument. With 030
purchased and installed on their FieldFox, users can both view and control their FieldFox.
Option 030 and the FieldFox app are not applicable to Android, BlackBerry, or Windows phone/tablet devices.
