Agilent EXA Signal Analyzer
Definitions and Requirements
Definitions and Requirements
This book contains signal analyzer specifications and supplemental information. The distinctio n amon g
specifications, typical performance, and nominal values are described as follows.
Definitions
•Specifications describe the performance of parameters covered by the product warranty (temperature
1
= 0 to 55°C
•95th percentile values indicate the breadth of the population (≈2σ) of performance tolerances
expected to be met in 95% of the cases with a 95% confidence, for any ambient temperature in the
range of 20 to 30°C. In addition to the statistical observations of a sample of instruments, these values
include the effects of the uncertainties of external calibration references. These values are not
warranted. These values are updated occasionally if a significant change in the statistically observed
behavior of production instruments is observed.
•Typical describes additional product performance information that is not covered by the product
warranty. It is performance beyond specification that 80% of the units exhibit with a 95% confidence
level over the temperature range 20 to 30°C. Typical performance does not include measurement
uncertainty.
•Nominal values indicate expected performance, or describe product performance that is useful in the
application of the product, but is not covered by the product warranty.
also referred to as "Full temperature range" or "Full range", unless otherwise noted).
Conditions Required to Meet Specifications
The following conditions must be met for the analyzer to meet its specifications.
•The analyzer is within its calibration cycle. See the General section of this chapter.
•Under auto couple control, except that Auto Sweep Time Rules = Accy.
•For signal frequencies < 10 MHz, DC coupling applied.
•Any analyzer that has been stored at a temperature range inside the allowed storage range but outside
the allowed operating range must be stored at an ambient temperature within the allowed operating
range for at least two hours before being turned on.
•The analyzer has been turned on at least 30 minutes with Auto Align set to Normal, or if Auto Align
is set to Off or Partial, alignments must have been run recently enough to prevent an Alert message. If
the Alert condition is changed from “Time and Temperature” to one of the disabled duration choices,
the analyzer may fail to meet specifications without informing the user.
Certification
Agilent Technologies certifies that this product met its published specifications at the time of shipment
from the factory. Agilent Technologi es further certifies that its calibration measurements are traceable to
the United States National Institute of Standards and Technology, to the extent allowed by the Institute’s
calibration facility, and to the calibration facilities of other International Standards Organization

Agilent EXA Signal Analyzer
Frequency and Time
c. In the band overlap regions, for example, 3.5 to 3.6 GHz, the analyzer may use either band for mea-
surements, 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 signal,
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 described as “3.5 to 7.0 GHz” represent nominal performance from 3.5 to 3.6 GHz,
and warranted performance from 3.6 to 7.0 GHz.

a. Calibration accuracy depends on how accurately the frequency standard was adjusted to 10 MHz. If the
adjustment procedure is followed, the calibration accuracy is given by the specification “Achievable
Initial Calibration Accuracy.”
b. The specification applies after the analyzer has been powered on for four hours.
c. Narrow temperature range performance is nominally linear with temperature. For example, for
25±3º C, the stability would be only three-fifths as large as the warranted 25±5º C, thus ±0.9 × 10
d. Standby mode does not apply power to the oscillator. Therefore warm-up applies every time the power
is turned on. The warm-up reference is one hour after turning the power on. Retracing also occurs
every time warm-up occurs. The effect of retracing is included within the “Achievable Initial Calibra-
tion Accuracy” term of the Accuracy equation.
e. The achievable calibration accuracy at the beginning of the calibration cycle includes these effects:
1) Temperature difference between the calibration environment and the use environment
2) Orientation relative to the gravitation field changing between the calibration environment and the
use environment
3) Retrace effects in both the calibration environment and the use environment due to turning the
instrument power off.

horizontal resolution
Example for EMC
a. The warranted performance is only the sum of all errors under autocoupled conditions. Under
non-autocoupled conditions, the frequency readout accuracy will nominally meet the specification
equation, except for conditions in which the RBW term dominates, as explained in examples below.
The nominal RBW contribution to frequency readout accuracy is 2% of RBW for RBWs from 1 Hz to
390 kHz, 4% of RBW from 430 kHz through 3 MHz (the widest autocoupled RBW), and 30% of RBW
for the (manually selected) 4, 5, 6 and 8 MHz RBWs.
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 accuracy, compared to 300 kHz for the 0.0.25% × span term, for a total of 355 kHz. In
this example, if an instrument had an unusually high RBW centering error of 7% of RBW (77 kHz) and
a span error of 0.20% of span (240 kHz), the total actual error (317 kHz) would still meet the computed
specification (355 kHz).
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 50 kHz of
error (0.25%) 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 sweep 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.
c. Specifications apply to traces in most cases, but there are exceptions. Specifications always apply to the
peak detector. Specifications apply when only one detector is in use and all active traces are s et to Clear
Write. Specifications 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 analyzer can be exceptionally good. As an exam-
ple, Agilent 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

in excess of the bucket quantization limitation were negligible.

a. Instrument conditions: RBW = 1 kHz, gate time = auto (100 ms), S/N ≥ 50 dB, frequency = 1 GHz
b. If the signal being measured is locked to the same frequency reference as the analyzer, the specified
count accuracy is ±0.100 Hz under the test conditions of footnote a. This error is a noisiness of the
result. It will increase with noisy sources, wider RBWs, lower S/N ratios, and source frequencies >
1 GHz.

a. The noise marker, band power marker, channel power and ACP all compute their results using the
power bandwidth 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 warranted 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 FFT Flattop. While the warranted performance only applies to the swept Gaussian filters, because only they are kept under statistical process
control, the other filters nominally have the same performance.
b. The ratio of the noise bandwidth (also known as the power bandwidth) to the RBW has the nominal
value and tolerance shown. The RBW can also be annotated by its noise bandwidth instead of this 3 dB
bandwidth. The accuracy of this annotated value is similar to that shown in the power bandwidth
accuracy specification.

Frequency and Time
c. Resolution Bandwidth Accuracy can be observed at slower sweep times than auto-coupled conditions.
Normal sweep rates cause the shape of the RBW filter displayed on the analyzer screen to widen by
nominally 6%. This widening declines to 0.6% nominal when the Swp Time Rules key is set to Accuracy instead of Normal. The true bandwidth, which determines the response to impulsive signals and
noise-like signals, is not affected by the sweep rate.

a. Signal frequencies between 18 and 26.5 GHz are prone to additional response errors due to modes in the
T ype-N connector used with frequency Option 526. With the use of Type-N to APC 3.5 mm adapter part
number 1250-1744, there are nominally six such modes. The effect of these modes with this connector
are included within these specifications.
b. See the Electronic Attenuator (Option EA3) chapter for Frequency Response using the electronic atten-
uator.
c. For Sweep Type = FFT, add the RF flatness errors of this table to the IF Frequency Response errors. An
additional error source, the error in switching between swept and FFT sweep types, is nominally ±0.01
dB and is included within the “Absolute Amplitude Error” specifications.
d. Specifications apply with DC coupling at all frequencies. With AC coupling, specifications apply at fre-
quencies of 50 MHz and higher. Statistical observations at 10 MHz show that most instruments meet the
specifications, but a few percent of instruments can be expected to have errors exceeding 0.5 dB at 10
MHz at the temperature extreme. The effect at 20 to 50 MHz is negligible, but not warranted.
e. Specifications for frequencies > 3.5 GHz apply for sweep rates ≤100 MHz/ms.

c. This column applies to the instantaneous analysis bandwidth in use. In the Spectrum Analyzer Mode,
this would be the FFT width.
d. The maximum error at an offset (f) from the center of the FFT width is given by the expression
± [Midwidth Error + (f × Slope)], but never exceeds ±Max Error. Here the Midwidth Error is the error at
the center frequency for a given FFT span. Usually, the span is no larger than the FFT width in which
case the center of the FFT width is the center frequency of the analyzer. When using the Spectrum Analyzer mode with an analyzer span is wider than the FFT width, the span is made up of multiple concatenated FFT results, and thus has multiple centers of FFT widths; in this case the f in the equation is the
offset from the nearest center. Performance is nominally three times better at most center frequencies.
e. The specification does not apply for frequencies greater than 3.6 MHz from the center in FFT widths of
7.2 to 8 MHz.
f. The “rms” nominal performance is the standard deviation of the response relative to the center fre-
quency , integrated across the span. This performance measure was observed at a center frequency in
each harmonic mixing band, which is representative of all center frequencies; it is not the worst case frequency.

Amplitude Accuracy and Range
a. Absolute amplitude accuracy is the total of all amplitude measurement errors, and applies over the fol-
lowing subset of settings and conditions: 1 Hz ≤ RBW ≤ 1 MHz; Input signal −10 to −50 dBm (details
below); Input attenuation 10 dB; span < 5 MHz (nominal additional error for span ≥ 5 MHz is
0.02 dB); all settings auto-coupled except Swp Time Rules = Accuracy; combinations of low signal
level and wide RBW use VBW ≤ 30 kHz to reduce noise. When using FFT sweeps, the signal must be
at the center frequency.
This absolute amplitude accuracy specification includes the sum of the following individual specifications under the conditions listed above: Scale Fidelity, Reference Level Accuracy, Display Scale
Switching Uncertainty, Resolution Bandwidth Switching Uncertainty, 50 MHz Amplitude Reference
Accuracy, and the accuracy with which the instrument aligns its internal gains to the 50 MHz Amplitude Reference.
The only difference between signals within the range ending at –50 dBm and those signals below that
level is the scale fidelity. Our specifications show the pos sibility of increased errors below –80 dBm at
the mixer, thus –70 dBm at the input. Therefore, one reasonably conservative approach to estimating
the Absolute Amplitude Uncertainty below –70 dBm at the mixer would be to add an additional
±0.10 dB (the difference between the above –80 dBm at the mixer scale fidelity at the lower level scale
fidelity) to the Absolute Amplitude Uncertainty.
b. Absolute Amplitude Accuracy for a wide range of signal and measurement settings, covers the 95th
percentile proportion with 95% confidence. Here are the details of what is covered and how the computation is made:
The wide range of conditions of RBW, signal level, VBW, reference level and display scale are discussed in footnote 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 instru ments. 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 frequency response adjustment frequencies. We
again compute the 95th percentile proportion with 95% confidence 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
parameters. To that rss we add the environmental ef fects of temperature vari ations across the 20 to
30°C range. These computations and measurements are made with the mechanical attenuator only in
circuit, set to the reference 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. Then the worst of the two computed 95th percentile results (they ere very close) is shown.
c. Same settings as footnote a, except that the signal level at the preamp input is −
power at preamp (dBm) = total power at input (dBm) minus input attenuation (dB). This specification
applies for signal frequencies above 100 kHz.

a. Supplemental information: The amplitude detection linearity specification applies at all levels below
−10 dBm at the input mixer; however, noise will reduce the accuracy of low level measurements. The
amplitude error due to noise is determined by the signal-to-noise ratio, S/N. If the S/N is large (20 dB or
better), the amplitude error due to noise can be estimated from the equation below, given for the
3-sigma (three standard deviations) level.
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.
b. The scale fidelity is warranted with ADC dither set to Medium. Dither increases the noise level by
nominally only 0.1 dB for the most sensitive case (preamp Off, best DANL frequencies). With dither
Off, scale fidelity for low level signals, around −60 dBm or lower, will nominally degrade by 0.2 dB.
c. Mixer level = Input Level − Input Attenuation
d. The relative fidelity is the error in the measured difference between two signal levels. It is so small in
many cases that it cannot be verified without being dominated by measurement uncertainty of the veri-
fication. Because of this verification difficulty, this specification gives nominal performance, based on
numbers that are as conservatively determined as those used in warranted specifications. We will con-
sider one example of the use of the error equation to compute the nominal performance.
Example: the accuracy of the relative level of a sideband around −60 dBm, with a carrier at −5 dBm,
using attenuation = 10 dB, RBW = 3 kHz, evaluated with swept analysis. The high level term is evalu-
ated with P1 = −15 dBm and P2 = −70 dBm at the mixer. This gives a maximum error within
±0.025 dB. The instability term is ±0.018 dB. The slope term evaluates to ±0.050 dB. The prefilter term
applies and evaluates to the limit of ±0.005 dB. The sum of all these terms is ±0.098 dB.
e. Errors at high mixer level s will nom inally be well within the range of ±0.045 dB × {exp[(P1 −
Pref)/(8.69 dB)] − exp[(P2 − Pref)/(8.69 dB)]} (exp is the natural exponent function, e
x
). In this expression, P1 and P2 are the powers of the two signals, in decibel units, whose relative power is being measured. Pref is −10 dBm (−10 dBm is the highest power for which linearity is specified). All these levels
are referred to the mixer level.
Chapter 1 41

f. Slope error will nominally be well within the range of ±0.0009 × (P1 − P2). P1 and P2 are defined in
footnote e.
g. 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) subject to a maximum of ±0.005 dB. (The maximum dominates for all but very
small differences.) P1 and P2 are defined in footnote e.

a. Large signals, even at frequencies not shown on the screen, can cause the analyzer to incorrectly mea-
sure on-screen signals because of two-tone gain compression. This specification tells how large an
interfering signal must be in order to cause a 1 dB change in an on-screen signal.
b. Specified at 1 kHz RBW with 100 kHz tone spacing. The compression point will nominally equal the
specification for tone spacing greater than 5 times the prefilter bandwidth. At smaller spacings, ADC
clipping may occur at a level lower than the 1 dB compression point.

c. Reference level and off-screen performance: The reference level (RL) behavior differs from some ear-
lier analyzers 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 logarithmic 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 measurement 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 fidelity) and small signal effects (noise), the measurement results can
change with RL changes when the input attenuation is set to auto.
d. The ADC clipping level declines at low frequencies (below 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 frequencies 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 frequency) at the ADC.

a. DANL for zero span and swept is measured in a 1 kHz RBW and normalized to the narrowest available
RBW, because the noise fig ure do es not depend on RBW and 1 kHz measurements are faster.
b. DANL below 10 MHz is affected by phase noise around the LO feedthrough signal. Specifications
apply with the best setting of the Phase Noise Optimization control, which is to choose the “Best
Close-in φ Noise" for frequencies below 25 kHz, and “Best W ide Offset φ Noise" for frequencies above
25 kHz.
c. Setting the IF Gain to Low is often desirable in order to allow high er power into the mi xer without
overload, better compression and better third-order intermodulation. When the Swept IF Gain is set to
Low, either by auto coupling or manual coupling, there is noise added above that specified in this table
for the IF Gain = High case. That excess noise appears as an additional noise at the input mixer. This
level has sub-decibel dependence on center frequency. To find the total displayed average noise at the
mixer for Swept IF Gain = Low, sum the powers of the DANL for IF Gain = High with this additional
DANL. To do that summation, compute DANLtotal = 10 × log (10^(DANLhigh/10) + 10^(AdditionalDANL / 10)). In FFT sweeps, the same behavior occurs, except that FFT IF Gain can be set to autorange, where it varies with the input signal level, in addition to forced High and Low settings.

a. The nominal performan ce of the phase noise at center frequencies different than the one at which the
specifications apply (1 GHz) depends on the center frequency, band and the offset. For low offset fre-
quencies, offsets well under 100 Hz, the phase noise increases by 20 × log[(f + 0.3225)/1.3225]. For
mid-offset frequencies such as 10 kHz, band 0 phase noise increases as 20 × log[(f + 5.1225)/6.1225].
For mid-offset frequencies in other bands, phase noise changes as 20 × log[(f + 0.3225)/6.1225] except
f in this expression should never be lower than 5.8. For wide offset frequencies, offsets above about
100 kHz, phase noise increases as 20 × log(N). N is the LO Multiple as shown on page 21; f is in GHz
units in all these relationships; all increases are in units of decibels.
b. Noise sidebands for lower offset frequencies, for example, 10 kHz, apply with the phase noise optimi-
zation (
PhNoise Opt) set to Best Close-in φ Noise. Noise sidebands for higher offset frequencies, for
example, 1 MHz, as shown apply with the phase noise optimization set to
c. 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. The internal 10 MHz reference phase noise is about
–120 dBc/Hz at 10 Hz offset; external references with poorer phase noise than this will cause poorer
performance than shown.

d. Expressed in decibels.
e. An ACP measurement measures the power in adjacent channels. The shape of the response versus fre-
quency of those adjacent channels is occasionally critical. One parameter of the shape is its 3 dB bandwidth. When the bandwidth (called the Ref BW) of the adjacent channel is set, it is the 3 dB bandwidth
that is set. The passband response is given by the convolution of two functions: a rectangle of width
equal to Ref BW and the power response versus frequency of the RBW filter used. Measurements and
specifications of analog radio ACPs are often based on defined bandwidths of measuring receivers, and
these are defined by their −6 dB widths, not their −3 dB widths. To achieve a passband whose −6 dB
width is x, set the Ref BW to be x − 0.572 × RBW.
f. Most versions of adjacent channel power measurements use negative numbers, in units of dBc, to refer
to the power in an adjacent channel relative to the power in a main channel, in accordance with ITU
standards. The standards for W-CDMA analysis include ACLR, a positive number represented in dB
units. In order to be consistent with other kinds of ACP measurements, this measurement and its specifications will use negative dBc results, and refer to them as ACPR, instead of positive dB results
referred to as ACLR. The ACLR can be determined from the ACPR reported by merely reversing the
sign.
g. The accuracy of the Adjacent Channel Power Ratio will depend on the mixer drive level and whether
the distortion products from the analyzer are coherent with those in the UUT. These specifications
apply even in the worst case condition of coherent analyzer and UUT distortion products. For ACPR
levels other than those in this specifications table, the optimum mixer drive level for accuracy is
approximately −37 dBm − (ACPR/3), where the ACPR is given in (negative) decibels.
h. To meet this specified accuracy when measuring mobile station (MS) or user equipment (UE) within
3 dB of the required −33 dBc ACPR, the mixer level (ML) must be optimized for accuracy. This optimum mixer level is −22 dBm, so the input attenuation must be set as close as possible to the average
input power − (−22 dBm). For example, if the average input power is −6 dBm, set the attenuation to
16 dB. This specification applies for the normal 3.5 dB peak-to-average ratio of a single code. Note
that, if the mixer level is set to optimize dynamic range instead of accuracy, accuracy errors are nominally doubled.
i. ACPR accuracy at 10 MHz offset is warranted when the input attenuator is set to give an average mixer
level of −14 dBm.
j. In order to meet this specified accuracy, the mixer level must be optimized for accuracy when measur-
ing node B Base Transmission Station (BTS) within 3 dB of the required −45 dBc ACPR. This optimum mixer level is −19 dBm, so the input attenuation must be set as close as possible to the average
input power −
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 optimize dynamic range instead of accuracy, accuracy errors are nominally doubled.
k. Accuracy can be excellent even at low ACPR levels assuming that the user sets the mixer level to opti-
mize 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.
(−19 dBm). For example, if the average input power is −7 dBm, set the attenuation to

l. Agilent measures 100% of the signal analyzers for dynamic range in the factory production process.
This measurement requires a near-ideal signal, which is impractical for field and customer use.
Because field verification is impractical, Agilent only gives a typical result. More than 80% of proto-
type instruments met this “typical” specification; the factory test line limit is set commensurate with an
on-going 80% yield to this typical.
The ACPR dynamic range is verified only at 2 GHz, where Agilent has the near-perfect signal avail-
able. The dynamic range is specified for the optimum mixer drive level, which is different in different
instruments and different conditions. The test signal is a 1 DPCH signal.
The ACPR dynamic range is the observed range. This typical specification includes no measurement
uncertainty.
m.ML is Mixer Level, which is defined to be the input signal level minus attenuation.
n. 3GPP requires the use of a root-raised-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 th e filter in this instrument. The ef fect of the RRC
filter and the effect of the RBW used in the measurement interact. The analyzer compens ates the shape
of the RRC filter to accommodate the RBW filter. The effectiveness of this compensation is summa-
rized in three ways:
− 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.
− 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 worst error for RBWs between 27 and 390 kHz is 0.05 dB for a 330 kHz
RBW filter.
− rms CW error: This error is a measure of the error in measuring a CW−like spurious component. It is
evaluated 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 testing 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 430 kHz RBW
filter.

a. The dynamic range specifi cation is the ratio of the channel 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 30 kHz RBW.
b. This dynamic range specification applies for the optimum mixer level, which is about −18 dBm. Mixer
level is defined to be the average input power minus the input attenuation.
c. The sensitivity is specified wit h 0 dB inp ut attenuation. It represents the noise limitations of the ana-
lyzer. It is tested without an input signal. The sensitivity at this offset is specified in the default 30 kHz
RBW, at a center frequency of 2 GHz.
d. The relative accuracy is a measure of the ratio of the power at the offset to the main channel power. It
applies for spectrum emission levels in the offsets that are well above the dynamic range limitation.
e. The absolute accuracy of SEM measurement is the same as the absolute accuracy of the spectrum ana-
lyzer. See “Absolute Amplitude Accuracy” on page 37 for more information. The numbers shown are

Noise Density at Mixer
at center frequency
a. This specification is defined to be the ratio of the clipping level (also known as “ADC Over Range”) to
the noise density. In decibel units, it can be defined as clipping_level [dBm]
− noise_density [dBm/Hz]; the result has units of dBFS/Hz (fs is “full scale”).
b. The noise density depends on the input frequency. It is lowest for a broad range of input frequencies
near the center frequency, and these specifications apply there. The noise de nsity can increase toward
the edges of the span. The effect is nominally well under 1 dB.
c. The primary determining element in the noise density is the “Displayed Average Noise Level” on
page 46.
d. DANL is specified with the IF Gain set to High, which is the best case for DANL but not for Clip-
ping-to-noise dynamic range. The core specifications “Displayed Average Noise Level” on page 46,
gives a line entry on the excess noise added by using IF Gain = Low, and a footnote explaining how to
combine the IF Gain noise with the DANL.
e. DANL is specified for log averaging, not power averaging, and thus is 2.51 dB lower than the true
noise density. It is also specified in the narrowest RBW, 1 Hz, which has a noise bandwidth slightly
wider than 1 Hz. These two effects together add up to 2.25 B.
f. As an example computation, consider this: For the case where DANL = −151 dBm in 1 Hz, IF Gain is
set to low, and the “Additional DANL” is −160 dBm, the total noise density computes to
−148.2 dBm/Hz and the Clipping-to-noise ratio for a −10 dBm clippi ng level is −138.2 dBFS/Hz.

3 VXA Vector Signal and WLAN
Modulation Analysis Application
This chapter contains specifications for the N9064A1 VXA vector signal and WLAN modulation
analysis measurement application.
Additional Definitions and Requirements
Because digital communications signals are noise-like, all measurements will have variations. The
specifications apply only with adequate averaging to remove those variations.
The specifications apply in the frequency range documented in In-Band Frequency Range.
The specifications for this chapter apply only to instruments with Frequency Option 503, 507, 513 or
526. For Instruments with higher frequency options, the performance is nominal only and not subject to
any warranted specifications.
Specs & Nominals
These specifications summarize the performance for the X-Series Signal Analyzer and apply to the VXA
measurement application inside the analyzer. Values shown in the column labeled "Specs & Nominals"
are a mix of warranted specifications, guaranteed-by-design parameters, and conservative but not
warranted observations of performance of sample instruments.
1. In software versions prior to A.06.00, the VXA measurement application product number was 89601X. Software
versions A.06.00 and beyond have renamed 89601X to N9064A.

a. DANL is specified in the narrowest resolution bandwidth (1 Hz) with log averaging, in accordance with
industry and historic standards. The effect of log averaging is to reduce the noise level by 2.51 dB. The
effect of using a 1 Hz RBW is to increase the measured noise because the noise bandwidth of the 1 Hz
RBW filter is nominally 1.056 Hz, thus adding 0.23 dB to the level. The combination of these effects
makes the sensitivity, in units of dBm/Hz, 2.27 dB higher than DANL in units of dBm in a 1 Hz RBW.

a. The IF frequency response includes effects due to RF circuits such as input filters, that are a function of
RF frequency, in addition to the IF passband effects.
b. Signal frequencies between 18 and 26.5 GHz are prone to additional response errors due to modes in the
T ype-N connector used with frequency Option 526. With the use of Type-N to APC 3.5 mm adapter part
number 1250-1744, there are nominally six such modes. These modes cause nominally up to −0.35 dB
amplitude change, with phase errors of nominally up to ±1.2
c. This column applies to the instantaneous analysis bandwidth in use. In the Spectrum analyzer Mode,
this would be the FFT width.
d. The maximum error at an offset (f) from the center of the FFT width is given by the expression ± [Mid-
width Error + (f × Slope)], but never exceeds ±Max Error. Here the Midwidth Error is the error at the
center frequency for the given FFT span. Usually, the span is no lar ger than the FFT width in which case
the center of the FFT width is the center frequency of the analyzer. In the Spectrum Analyzer mode,
when the analyzer span is wider than the FFT width, the span is made up of multiple concatenated FFT
results, and thus has multiple centers of FFT widths so the f in the equation is the offset from the nearest
center. These specifications include the effect of RF frequency response as well as IF frequency
response at the worst case center frequency. Performance is nominally three times better at most center
frequencies.
e. The specification does not apply for frequencies greater than 3.6 MHz from the center in FFT widths of
7.2 to 8 MHz.
f. The “RMS” nominal performance is the standard deviation of the response relative to the center fre-
quency , integrated across the span. This performance measure was observed at a center frequency in
each harmonic mixing band, which is representative of all center frequencies; it is not the worst case
frequency.

level experimentally. A SCPI command is also available for that purpose.
b. Mixer level is signal level minus input attenuation.
c. The available gain to reach the predicted mixer level will vary with center frequency. Combinations of
high gains and high frequencies will not achieve the gain required, increasing the full scale level.

revised-version of the table on page 48, modified to reflect the
effect of Option B40, is shown in its place in this chapter. The
image responses part of that table have the same warranted
limits, but apply at different frequencies as shown in the table.
The "higher order RF spurs" line is slightly degraded. Also,
