三、测试端口输出规格
High power in the N991xC refers to the analyzer’s target output power level when the Power Setting is
High. An example
• N991xC: For a 58.4 MHz to 10 GHz frequency sweep, the analyzer achieves an
8 dBm power level
across the band
Low power level for N991xC analyzers flattens at -50 dBm across the entire frequency band and is the
分析仪’s 输出 when 功率设置低
Max leveled power in the N991xC refers to the maximum leveled (flattened) power achieved across the
designated frequency range. An example
• N991xC: For a
58.4 MHz to 10 GHz frequency sweep with the analyzer configured to measure all four
S-parameters, needing both ports 1 and 2, the maximum power the analyzer can be set to is
7 dBm.

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.

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)
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

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.
