CAT and VNA mode calibrations
FieldFox analyzers offer three tiers of calibrations, thus providing users with different levels of calibration
CalReady is the most basic calibration and is sufficient for a quick pass/fail or go/no go verification. Every
FieldFox is calibrated at the factory, at test ports
1 and 2, at room temperature. CalReady can be applied
either as an “enhanced response CalReady” or a “2-port CalReady.” The default setting is
2-port
CalReady, so correction is applied to both ports. A user preference allows user to change the CalReady
methodology to enhanced response CalReady
A 30-minute warm-up period is recommended for a quick test. A
60-minute warm-up is necessary for
more stringent 测试要求
If CalReady is the basis for most measurements, the annual cal cycle must be followed, as the CalReady
Standard calibrations
Standard calibrations are the most accurate calibrations offered in FieldFox. FieldFox’s calibration engine
is based on Keysight’s flagship PNA calibration engine, and as such, offers many of the standard
calibrations. FieldFox supports both coaxial and waveguide calibrations. The table below lists the
commonly used calibrations
Keysight recommends a 30-minute warm-up period for standard calibrations. For ultimate in stability and
accuracy, a
90-minute warm-up period is necessary.
（含） 和（不含） 隔离度
条件：errors. 1-port OSL (Port 1) Open, short, and load 1-port OSL (Port 2) Traditional 1-port calibration for reflection measurements. Corrects for directivity, source match, and frequency response errors.
SSL (for waveguide) For waveguide calibrations, depending on the calibration kit definition, this is
Simultaneous magnitude and phase correction of frequency response errors for
either reflection or transmission measurements. Isolation corrects for crosstalk
Reverse enhanced response
Corrects for frequency response and source match. Partial correction for load
match for low-loss reciprocal devices
QSOLT (2-port) QSOLT or Quick short-open-load-thru is FieldFox’s default recommended
calibration for insertable devices. Full
12-term error correction. Requires fewer
connections, compared to traditional SOLT (4 compared to 7). Corrects for
directivity, source match, reflection frequency response, load match, and
transmission 频率响应
Full
2-port (unknown thru
FieldFox’s default recommended calibration for non-insertable devices. Full
12-
term error correction. Beneficial for characterizing non-insertable devices such
as Type-N to 3.5 mm, or female-female devices. Corrects for directivity, source
match, reflection frequency response, load match, and transmission frequency
TRL TRL or thru-reflect-line compensates for directivity, reflection, and transmission
frequency response in both the forward and reverse directions.
Note: FieldFox does not offer the traditional SOLT calibration. Instead, it offers the more accurate Full
2- port (unknown thru), and
FieldFox’s guided calibration wizard
条件：kit. FieldFox’s calibration wizard ensures a valid calibration selection.
FieldFox’s calibration wizard recommends a calibration type and calibration kit based on selected
parameters and connector types. Alternatively, users can select their own calibration type and calibration
Interpolation error correction
With any type of accuracy enhancement applied, interpolated mode recalculates the error coefficients
when the test frequencies are changed. The number of points can be increased or decreased, and the
start/stop frequencies can be changed, but the resulting frequency span must be a subset of the original

215)
The performance listed in TDR cable measurements, VNA time domain, mixed-mode S-parameters and
FieldFox microwave (combination) analyzers N9916D, N9917D, N9918D
条件：The TDR cable option adds time domain reflectometry (TDR) measurements to FieldFox’s CAT mode.
FieldFox’s TDR measurements are based on an inverse Fourier transform of the frequency-domain data.
TDR measurements are useful in not only identifying the location of faults along cables, but also the
nature of the fault. Resistive, inductive and capacitive faults will each have a different response. These
differences help engineers and technicians’ trouble-shoot line faults.
X-axis: distance (meters or feet)
VNA Time Domain (Option
010)
In time-domain mode, FieldFox computes the inverse Fourier transform of the frequency-domain data to
Gating Start, stop, center, span, and on/off
Numbers of points, velocity vector, line loss, window shape, independent control for all four traces
时间 stimulus 模式
条件：domain data should extend from DC (extrapolated value) to a higher value.
Low-pass impulse Low-pass impulse response is used to measure low-pass devices.
Low-pass step Low-pass step is similar to a traditional time domain reflectometer (TDR)
stimulus waveform. It is used to measure low-pass devices. The frequency-
Bandpass impulse The bandpass impulse simulates a pulsed RF signal and is used to measure
The windowing function can be used to filter the frequency domain data and thereby reduce overshoot and ringing
in the time domain response
Windows Minimum, medium and maximum, manual entry of Kaiser Beta and impulse
The gating function can be used to selectively remove reflection or transmission time domain responses. In
converting back to the frequency domain, the effects of the responses outside the gate are removed. The results
Gate shapes 最大值, wide, 正常, 最小值
Mixed-Mode S-Parameters (Option
212)
Mixed-mode S-parameters are also known as balanced measurements.
Scc11 Common mode reflection
Sdd11 Differential mode reflection
Scd11 Differential mode stimulus, common mode response
Sdc11 Common mode stimulus, differential mode response
FieldFox’s mixed-mode S-parameter measurements require the use of the default factory calibration or a
user 2-port calibration. So, the FieldFox analyzer must be equipped with 2-port measurement functionality
to measure mixed-mode S-parameters. Mixed-mode S-parameters are an extension of the VNA
条件：device measurements. The results are shown on a large display in digital format.
Vector Voltmeter (VVM) (Option
308)
With vector voltmeter mode, you can characterize the difference between two measurements easily. The
zeroing function allows you to create a reference signal and characterize the difference between two

不确定度 contributions
Jitter Random independent events (fluctuations) within the bandwidth
occurring during the noise measurement
ENR Excess noise ratio of the hot noise source connected to the DUT
during the measurement
Mismatch Errors resulting from reflections due to impedance differences
User calibration
Errors due to the optional user calibration which is performed with a
defined noise standard (ENR source) connected to the input of an
LNA, and fixturing/cables used in the DUT measurement, and port

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. Alternately, users can create custom standards and
import them into FieldFox analyzers
条件：With time gating, you can measure the spectrum of a periodic signal during a specified time interval.
Pulsed-RF signals are an example of a periodic signal that can be measured with time gating. For
components that would otherwise be hidden. FieldFox’s time gating method is a Gated FFT.
Spectrum Analyzer Time Gating (Option
238)
example, you can measure the pulse during the on period, not the transition or the off period. Or you can
exclude interfering signals such as a periodic transient. Time gating allows you to view spectral

系统说明
条件：InstAlign technique, ERTA can be used to make accurate gain or loss measurements.
ERTA can be used to measure the scalar transmission gain or loss of an RF system. It is useful when
measuring long lossy cables where the two ends cannot easily be brought together, such as those bolted
in on ships or aircrafts. It is also useful in measuring the insertion loss of waveguide systems, or using the
frequency-offset feature, devices such as mixers and converters.
ERTA measurements are based on two FieldFox units; one at each end of the measured DUT. One
FieldFox is the source and reference receiver (R), while the other is the measurement receiver (B). The
two FieldFox units are synchronized using hardware triggering. By taking advantage of FieldFox’s
