Mode” column), the desired 1st LO harmonic is higher than the tuned frequency by the 1st IF.
Frequency and Time a. In the band overlap regions, for exam ple, 3.5 to 3.6 GHz, the analyzer may use either band for measurements, in this example Band 0 or Band 1. The analyzer gives preference to the band with the better overall specifications (which is the lower numbered band for all frequencies below
26 GHz), but will choose the other band if doing so is
necessary to achieve a sweep having minimum band crossings. For example, with CF =
3.58 GHz, with a span of
40 MHz or less, the analyzer uses Band 0, because the stop frequency is
3.6 GHz or less, allowing a span without
band crossings in the preferred band. If the span is between 40 and 160 MHz, the analyzer uses Band
1, because
the start frequency is above 3.5 GHz, allowing the sweep to be done without a band crossing in Band
1, though
the stop frequency is above 3.6 GHz, preventing a Band
0 sweep without band crossing. With a span greater than
160 MHz, a band crossing will be required: the analyzer sweeps up to 3.6 GHz in Band
0; then executes a band
crossing and continues the sweep in Band
1.
Specifications are given separately for each band in the band overlap regions. One of these specifications is for the
preferred band, and one for the alternate band. Continuing with the example from the previous paragraph
(3.58 GHz), the preferred band is band 0 (indicated as frequencies under
3.6 GHz) and the alternate band is band
1 (3.5 to 8.4 GHz). The specifications for the preferred band are warranted. The specifications for the alternate
band are not warranted in the band overlap region, but performance is nominally the same as those warranted
specifications in the rest of the band. Again, in this example, consider a signal at 3.58 GHz. If the sweep has been
configured so that the signal at 3.58 GHz is measured in Band 1, the analysis behavior is nominally as stated in the
Band
1 specification line (3.5 to 8.4 GHz) but is not warranted. If warranted performance is necessary for this sig-
nal, the sweep should be reconfigured so that analysis occurs in Band
0. Another way to express this situation in
this example Band 0/Band 1 crossing is this: The specifications given in the “Specifications” column which are
from 3.6 to 8.4 GHz.

a. The warranted performance is only the sum of all errors under autocoupled conditions. Under non-autocoupled

c. Specifications apply to traces in most cases, but ther e are exceptions. Specifications always apply to the peak
detector. Specifications apply when only one detector is in use and all active traces are set to Clear Write. Spec-
points, the errors in excess of the bucket quantization limitation were negligible.
readout accuracy is 2% of RBW for RBWs from 1 Hz to 390 kHz, 4% of RBW from 430 kHz through
3 MHz (the
First example: a 120 MHz span, with autocoupled RBW. The autocoupled ratio of span to RBW is
106:1, so
the RBW selected is 1.1 MHz. The 5% × RBW term contributes only
55 kHz to the total frequency readout accu-
Second example: a 20 MHz span, with a
4 MHz RBW. The specification equation does not apply because the
Span: RBW ratio is not autocoupled. If the equation did apply, it would allow
20 kHz of error (0.10%) due to the
span and 200 kHz error (5%) due to the RBW. For this non-autocoupled RBW, the RBW error is nominally
30%
or 1200 kHz.
b. Horizontal resolution is due to the marker reading out one of the trace points. The points are spaced by
span/(Npts – 1), where Npts is the number of sweep points. For example, with the factory preset value of 1001
sweep points, the horizontal resolution is span/1000. However, there is an exception: When both the detector
mode is “normal” and the span > 0.25 × (Npts – 1) × RBW, peaks can occur only in even-numbered points, so
the effective horizontal resolution becomes doubled, or span/500 for the factory preset case. When the RBW is
autocoupled and there are 1001 sweep points, that exception occurs only for spans
>750 MHz
ifications also apply when only one detector is in use in all active traces and the "Restart" key has been pressed
since any change from the use of multiple detectors to a single detector. In other cases, such as when multiple
simultaneous detectors are in use, additional errors of 0.5
1.0 or 1.5 sweep points will occur in some detectors
depending on the combination of detectors in use. d. In most cases, the frequency readout accuracy of the an alyzer can be exceptionally good. As an example, Key- sight has characterized the accuracy of a span commonly used for Electro-Magnetic Compatibility (EMC) testing using a source frequency locked to the analyzer. Ideally, this sweep would include EMC bands C and D and thus
sweep from 30 to 1000 MHz. Ideally, the analysis bandwidth would be
120 kHz at −6 dB, and the spacing of the
points would be half of this (60 kHz). With a start frequency of 30 MHz and a stop frequency of 1000.2 MHz and
a total of 16168 points, the spacing of points is ideal. The detector used was the Peak detector. The accuracy of
frequency readout of all the points tested in this span was with ±0.0032% of the span. A perfect analyzer with
this many points would have an accuracy of ±0.0031% of span. Thus, even with this large number of display

Frequency and Time b. The noise marker, band power marker, channel power a nd ACP all compute their results using the power band- width of the RBW used for the measurement. Power bandwidth accuracy is the power uncertainty in the results of these measurements due only to bandwidth-related errors. (The analyzer knows this power bandwidth for
each RBW with greater accuracy than the RBW width itself, and can therefore achieve lower errors.) The war-
ranted specifications shown apply to the Gaussian RBW filters used in swept and zero span analysis. There are
four different kinds of filters used in the spectrum analyzer: Swept Gaussian, Swept Flattop, FFT Gaussian and
tolerance shown. The RBW can also be annotated by its noise bandwidth instead of this

accuracy of this annotated value is similar to that shown in the power bandwidth

The wide range of conditions of RBW, signal level, VBW, reference level and display scale are discussed in foot-
parameters. To that rss we add the environmental effects of temperature variations across the 20 to 30°C range.
note a. There are 44 quasi-random combinations used, tested at a
50 MHz signal frequency. We compute the
95th percentile proportion with 95% confidence for this set observed over a statistically significant number of
instruments. Also, the frequency response relative to the
50 MHz response is characterized by varying the signal
across a large number of quasi-random verification frequencies that are chosen to not correspond with the fre-
quency response adjustment frequencies. We again compute the
95th percentile proportion with 95% confi-
dence for this set observed over a statistically significant number of instruments. We also compute the
95th
percentile accuracy of tracing the calibration of the
50 MHz absolute amplitude accuracy to a national standards
organization. We also compute the 95th percentile accuracy of tracing the calibration of the relative frequency
response to a national standards organization. We take the root-sum-square of these four independent Gaussian
These computations and measurements are made with the mechanical attenuator only in circuit, set to the refer-
ence state of 10 dB.
A similar process is used for computing the result when using the electronic attenuator under a wide range of
settings: all even settings from 4 through 24 dB inclusive, with the mechanical attenuator set to 10 dB. The
95th
percentile result was
0.21 dB.
c. Same settings as footnote a, except that the signal level at the preamp input is

The errors due to S/N ratio can be further reduced by averaging results. For large S/N (20 dB or better), the
3-sigma level can be reduced proportional to the square root of the number of averages taken.

f. The stability of the analyzer gain can be an error term of importance when no settings have changed. These have
been studied carefully in the UXA. One source of instability is the variation in analyzer response with time when
fully warmed up in a stable lab environment. This has been observed to be well modeled as a random walk pro-
cess, where the difference in two measurements spaced by time t is given by a × sqrt(t), where a is
0.0019 dBrms
per root minute. The other source of instability is updated alignments from running full or partial alignments in the
background or invoking an alignment. Invoked alignments (Align Now, All) have a standard deviation of
0.0018 dB, and performing these will restart the random walk behavior. Partial alignments (Auto Align set to "Par-
tial") have a standard deviation that is, coincidentally, also
0.0018 dBrms, and only occurs once every ten min-
utes. The standard deviation from full background alignment (Auto Align set to "Normal") is
0.015 dBrms; with
these alignments on, there is no additional random walk behavior. (Keysight recommends setting alignments
(Auto Align) to Normal in order to make the best measurements over long periods of time or in environments
without very high temperature stability. For short term measurements in highly stable environments, setting
alignments to Partial can give the best stability. Setting Alignments to Off is not recommended where stability
matters.) g. Slope error will nominally be well within the range of ±0.0004 × (P1 − P2). P1 and P2 are defined in footnote e. h. A small additional error is possible. In FFT sweeps, this error is possible for spans under
4.01 kHz. For non-FFT measurements, it is possible for RBWs of 3.9 kHz or less. The error is well within the range of ±0.0021 × (P1 - P2)

Dynamic Range c. Reference level and off-screen performance: The referenc e level (RL) behavior differs from some earlier analyz- ers in a way that makes this analyzer more flexible. In other analyzers, the RL controlled how the measurement was performed as well as how it was displayed. Because the logarithmic amplifier in these analyzers had both
range and resolution limitations, this behavior was necessary for optimum measurement accuracy. The logarith-
mic amplifier in this signal analyzer, however, is implemented digitally such that the range and resolution greatly
exceed other instrument limitations. Because of this, the analyzer can make measurements largely independent
of the setting of the RL without compromising accuracy. Because the RL becomes a display function, not a mea-
surement function, a marker can read out results that are off-screen, either above or below, without any change
in accuracy. The only exception to the independence of RL and the way in which the measurement is performed
is in the input attenuation setting: When the input attenuation is set to auto, the rules for the determination of
the input attenuation include dependence on the reference level. Because the input attenuation setting controls
the tradeoff between large signal behaviors (third-order intermodulation, compression, and display scale fidel-
ity) and small signal effects (noise), the measurement results can change with RL changes when the input atten-
uation is set to auto. d. Mixer power level (dBm) = input power (dBm) − input attenuation (dB). e. The ADC clipping level declines at low frequencies (bel ow 50 MHz) when the LO feedthrough (the signal that appears at 0 Hz) is within 5 times the prefilter bandwidth (see table) and must be handled by the ADC. For
example, with a
300 kHz RBW and prefilter bandwidth at 966 kHz, the clipping level reduces for signal frequen-
cies below 4.83 MHz. For signal frequencies below
2.5 times the prefilter bandwidth, there will be additional
reduction due to the presence of the image signal (the signal that appears at the negative of the input signal fre-

When spectrum analyzers were not as good as they are now, these distortion products were easily mea-
sured. As spectrum analyzers improved, the measurement began to be made at higher levels and extrapo-
lated to the industry-standard
−30 dBm test level. This extrapolation was justified by excellent conformance
with the third-order model, wherein distortion in dBc was given by twice the difference between the test
tone level and the intercept, both given in dBm units. In UXA, we no longer make that extrapolation in this

Nominal Dynamic Range vs. Offset Frequency vs. RBW [Plot]
One reason we don’t extrapolate is that the model does not work as well as it had with higher levels of dis-
tortion in older and less capable analyzers, so that the computation is misleading; distortions at low test lev-
els will be modestly higher than predicted from the formula. The second reason is that the distortion

should be used. When the setting is changed to Best Spur s, the maximum spurious response is held to –90 dBc,

d. Specifications are given with the internal frequency reference. The phase noise at offsets below
100 Hz is
impacted or dominated by noise from the reference. Thus, performance with external references will not follow the
curves and specifications. When using an external reference with superior phase noise, we recommend setting
the external reference phase-locked-loop bandwidth to wide (60 Hz), to take advantage of that superior perfor-
mance. When using an external reference with inferior phase noise performance, we recommend setting that
bandwidth to narrow (15 Hz). In these relationships, inferior and superior phase noise are with respect to

e. Keysight measures 100% of the signal analyzers for phase noise at 10 Hz offset from a
1 GHz carrier in the factory
production process. This measurement requires a signal of exceptionally low phase noise that is characterized
with specialized processes. It is impractical for field and customer use. Because field verification is impractical,
Keysight only gives a typical result. More than
80% of prototype instruments met this "typical" specification; the
factory test line limit is set commensurate with an on-going
80% yield to this typical. Like all typical specifications
there is no guardbanding for measurement uncertainty. The factory test line limit is consistent with a warranted
specification of –89 dBc/Hz.
f. Analyzer-contributed phase noise at the low levels of this offset requires advanced verification techniques
because broadband noise would otherwise cause excessive measurement error. Keysight uses a high level low
phase noise CW test signal and sets the input attenuator so that the mixer level will be well above the normal
top-of-screen level (-10 dBm) but still well below the
1 dB compression level. This improves dynamic range (car-
rier to broadband noise ratio) at the expense of amplitude uncertainty due to compression of the phase noise
sidebands of the analyzer. (If the mixer level were increased to the "1 dB Gain Compression Point," the compres-
sion of a single sideband is specified to be
1 dB or lower. At lower levels, the compression falls off rapidly. The
compression of phase noise sidebands is substantially less than the compression of a single-sideband test signal,
further reducing the uncertainty of this technique.) Keysig ht also measures the broadband noise of the analyzer
without the CW signal and subtracts its power from the measured phase noise power. The same techniques of

date the RBW filter. The effectiveness of this compensation is summarized in three ways:
Power Suite Measurements i. ACPR accuracy at 10 MHz offset is warranted when the in put attenuator is set to give an average mixer level of
−14 dBm.
j. In order to meet this specified accuracy, the mixer leve l must be optimized for accuracy when measuring node B
Base Transmission Station (BTS) within 3 dB of the required −45 dBc ACPR. This optimum mixer level is
−18
dBm, so the input attenuation must be set as close as possible to the average input power − (−18 dBm). For
example, if the average input power is
−6 dBm, set the attenuation to 12 dB. This specification applies for the
normal 10 dB peak-to-average ratio (at 0.01% probability) for Test Model 1. Note that, if the mixer level is set to
k. Accuracy can be excellent even at low ACPR levels assu ming that the user sets the mixer level to optimize the
dynamic range, and assuming that the analyzer and UUT distortions are incoherent. When the errors from the
UUT and the analyzer are incoherent, optimizing dynamic range is equivalent to minimizing the contribution of
analyzer noise and distortion to accuracy, though the higher mixer level increases the display scale fidelity
errors. This incoherent addition case is commonly used in the industry and can be useful for comparison of
analysis equipment, but this incoherent addition model is rarely justified. This derived accuracy specification is
based on a mixer level of −14 dBm.
l. The dynamic range shown with Noise Correction = Off a pplies with Noise Floor Extension On. (Noise Correction
is the process within the measurement of making a calibration of the noise floor at the exact analyzer settings
used for the measurement. Noise Floor Extension is the factory calibration of the noise floor.)
m. Keysight measures 100% of the signal analyzers for dynamic range in the factory production process. This mea-
surement requires a near-ideal signal, which is impractical for field and customer use. Because field verification
is impractical, Keysight only gives a typical result. More than
80% of prototype instruments met this “typical”
The ACPR dynamic range is verified only at 2 GHz, where Keysight has the near-perfect signal available. The
dynamic range is specified for the optimum mixer drive level, which is different in different instruments and dif-

3GPP requires the use of a root-rai sed-cosine filter in evaluating the ACLR of a device. The accuracy of the
passband shape of the filter is not specified in standards, nor is any method of evaluating that accuracy. This
footnote discusses the performance of the filter in this instrument. The effect of the RRC filter and the effect of
the RBW used in the measurement interact. The analyzer compensates the shape of the RRC filter to accommo-
− White noise in Adj Ch: The compensated RRC filter nominally has no errors if the adjacent channel has a
spectrum that is flat across its width
条件：worst error for RBWs between 27 and 390 kHz is 0.05 dB for a 330 kHz RBW filter.
− TOI−induced spectrum: If the spectrum is due to third−order intermodulation, it has a distinctive shape. The
computed errors of the compensated filter are −0.001 dB for the
100 kHz RBW used for UE testing with the
IBW method. It is 0.000 dB for the
27 kHz RBW filter used for BTS testing with the Filtered IBW method. The

by computing the root of the mean of the square of the power error across all frequencies within the adjacent
channel. The computed rms error of the compensated filter is 0.012 dB for the
100 kHz RBW used for UE test-
ing with the IBW method. It is 0.000 dB for the
27 kHz RBW filter used for BTS testing. The worst error for
RBWs between 27 kHz and 470 kHz is 0.057 dB for a

a. The dynamic range specification is the ratio of the ch annel power to the power in the offset specified. The
dynamic range depends on the measurement settings, such as peak power or integrated power. Dynamic range
specifications are based on default measurement settings, with detector set to average, and depend on the
mixer level. Default measurement settings include
