Agilent CXA Signal Analyzer

Definitions and Requirements

Definitions and Requirements
This book contains signal analyzer specifications and supplemental information. The distinction among specifications, typical performance, and nominal values are described as follows.

Definitions

Specifications describe the performance of parameters covered by the product warranty (temperature = 5 to 50°C, unless otherwise noted).
95th percentile values indicate the breadth of the population (> 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.
2σ) of performance tolerances

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.
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 Technologies 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 members.

Frequency and Time
a. In the band overlap regions, for example, 2.95 to 3.0 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, but will choose the other band if doing so is necessary to achieve a sweep having minimum band crossings. For example, with CF = 2.98 GHz, with a span of 40 MHz or less, the analyzer uses Band 0, because the stop frequency is 3.0 GHz or less, allowing a span without band crossings in the preferred band. If the span is between 40 and 60 MHz, the analyzer uses Band 1, because the start frequency is above 2.95 GHz, allowing the sweep to be done without a band crossing in Band 1, though the stop frequency is above 3.0 GHz, preventing a Band 0 sweep without band crossing. With a span greater than 60 MHz, a band crossing will be required: the analyzer sweeps up to
3.0 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 (2.98 GHz), the preferred band is band 0 (indicated as frequencies under
3.0 GHz) and the alternate band is band 1 (2.95 to 3.8 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 2.98 GHz. If the sweep has been configured so that the signal at
2.98 GHz is measured in Band 1, the analysis behavior is nominally as stated in the Band 1 specification line (2.95 – 3.8 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 “2.95 to 3.8 GHz” represent nominal performance
from 2.95 to 3.0 GHz, and warranted performance from 3.0 to 3.8 GHz.

Single detector only

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 4% of RBW for RBWs from 1 Hz to 3 MHz (the widest autocoupled RBW), and 30% of RBW for the (manually selected) 4, 5, 6 and 8 MHz RBWs. 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 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.
c. In most cases, the frequency readout accuracy of the analyzer can be exceptionally good. As an example, 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 ±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 points, the errors in excess of the
bucket quantization limitation were negligible.

a. Horizontal resolution is due to the marker reading out one of the trace points. The points are spaced by span/(Npts

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. 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.
c. The RBW filters are implemented digitally, and the Selectivity is defined to be 4.1:1. Verifying the selectivity with
RBW’s above 100 kHz becomes increasing problematic due to SNR affecting the 60 dB measurement.

a. Reference level and off-screen performance: The reference level (RL) behavior differs from previous analyzers
(except PSA) in a way that makes the Agilent CXA Signal Analyzer more flexible. In previous analyzers, the RL controlled how the measurement was performed as well as how it was displayed. Because the logarithmic ampli­fier in previous analyzers had both range and resolution limitations, this behavior was necessary for optimum mea­surement accuracy. The logarithmic amplifier in the CXA signal analyzer, however, is implemented digitally such that the range and resolution greatly exceed other instrument limitations. Because of this, the CXA signal 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 and compression) and small signal effects (noise), the measurement results can change with RL changes when the
input attenuation is set to auto.

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 pass-band effects.
b. 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. 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 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 than the
maximum error at most center frequencies.
c. The specification does not apply for frequencies greater than 3.6 MHz from the center in FFT Widths of 7.2 to 8
MHz.
d. The "RMS" nominal performance is the standard deviation of the response relative to the center frequency, integrated
across a 10 MHz span. This performance measure was observed at a single center frequency in each harmonic mixing band, which is representative of all center frequencies; the observation center frequency is not the worst case center
frequency.

a. Absolute amplitude accuracy is the total of all amplitude measurement errors, and applies over the following sub-
set of settings and conditions: 1 Hz RBW 1 MHz; Input signal 10 to 50 dBm; 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.
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.
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 108 quasirandom 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 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
effects of temperature variations across the 20 to 30°C range.
c. Same settings as footnote a, except that the signal level at the preamp input is 40 to 80 dBm. Total power at preamp
(dBm) = total power at input (dBm) minus input attenuation (dB). This specification applies for signal frequencies above 100 kHz.

a. Reference level and off-screen performance: The reference level (RL) behavior differs from previous analyzers
(except PSA) in a way that makes the Agilent CXA Signal Analyzer more flexible. In previous analyzers, the RL controlled how the measurement was performed as well as how it was displayed. Because the logarithmic amplifier in previous analyzers had both range and resolution limitations, this behavior was necessary for optimum measurement accuracy. The logarithmic amplifier in the CXA signal analyzer, however, is implemented digitally such that the range and resolution greatly exceed other instrument limitations. Because of this, the CXA signal 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 and compression) and small signal effects (noise),
the measurement results can change with RL changes when the input attenuation is set to auto.
b. Because reference level affects only the display, not the measurement, it causes no additional error in measurement
results from trace data or markers.

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.

σ

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 On. Dither increases the noise level by nominally only 0.24 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. Reference level and off-screen performance: The reference level (RL) behavior differs from some earlier 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 attenuator setting: When the input attenuator 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 and compression) and small signal effects (noise), the measurement results can
change with RL changes when the input attenuation is set to auto. d. Mixer level = Input Level Input Attenuator e. 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 verification. 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 consider 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 attenuator
= 10 dB, RBW = 3 kHz, evaluated with swept analysis. The high level term is evaluated with P1 = 15 dBm and P2 =
70 dBm at the mixer. This gives a maximum error within ±0.039 dB. The instability term is ±0.018 dB. The slope
term evaluates to ±0.050 dB. The sum of all these terms is ±0.107 dB.

a. DANL for zero span and swept is normalized in two ways and for two reasons. DANL is measured in a 1 kHz
RBW and normalized to the narrowest available RBW, because the noise figure does not depend on RBW and 1 kHz measurements are faster. The second normalization is that DANL is measured with 10 dB input attenuation and normalized to the 0 dB input attenuation case, because that makes DANL and third order intermodulation test
conditions congruent, allowing accurate dynamic range estimation for the analyzer.
b. DANL below 10 MHz is dominated by phase noise around the LO feedthrough signal.

e. An ACP measurement measures the power in adjacent channels. The shape of the response versus frequency 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 .
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 deter-
mined 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. The Fast method has a slight decrease in accuracy in only one case: for BTS measurements at 5 MHz offset, the
accuracy degrades by ±0.01 dB relative to the accuracy shown in this table.
i. 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 −20 dBm, so the input attenuation must be set as close as possible to the average input power − (−20 dBm). For example, if the average input power is 6 dBm, set the attenuation to 14 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.
j. ACPR accuracy at 10 MHz offset is warranted when the input attenuator is set to give an average mixer level
of 10 dBm.
k. In order to meet this specified accuracy, the mixer level 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 5 dBm, set the attenuation to 13 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.
l. Accuracy can be excellent even at low ACPR levels assuming 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 13 dBm.
m.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 prototype 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 available. 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.

a. The RBW method measures the power in the adjacent channels within the defined resolution bandwidth. The noise
bandwidth of the RBW filter is nominally 1.055 times the 3.01 dB bandwidth. Therefore, the RBW method will nominally read 0.23 dB higher adjacent channel power than would a measurement using the integration bandwidth method, because the noise bandwidth of the integration bandwidth measurement is equal to that integration band­width. For cmdaOne ACPR measurements using the RBW method, the main channel is measured in a 3 MHz RBW, which does not respond to all the power in the carrier. Therefore, the carrier power is compensated by the expected under-response of the filter to a full width signal, of 0.15 dB. But the adjacent channel power is not com­pensated for the noise bandwidth effect. The reason the adjacent channel is not compensated is subtle. The RBW method of measuring ACPR is very simi­lar to the preferred method of making measurements for compliance with FCC requirements, the source of the specifications for the cdmaOne Spur Close specifications. ACPR is a spot measurement of Spur Close, and thus is best done with the RBW method, even though the results will disagree by 0.23 dB from the measurement made
with a rectangular passband.
b. The specified ACPR accuracy applies if the measured ACPR substantially exceeds the analyzer dynamic range at
the specified offset. When this condition is not met, there are additional errors due to the addition of analyzer spec­tral components to UUT spectral components. In the worst case at these offsets, the analyzer spectral components are all coherent with the UUT components; in a more typical case, one third of the analyzer spectral power will be coherent with the distortion components in the UUT. Coherent means that the phases of the UUT distortion com­ponents and the analyzer distortion components are in a fixed relationship, and could be perfectly in-phase. This coherence is not intuitive to many users, because the signals themselves are usually pseudo-random; nonetheless, they can be coherent. When the analyzer components are 100% coherent with the UUT components, the errors add in a voltage sense. That error is a function of the signal (UUT ACPR) to noise (analyzer ACPR dynamic range limitation) ratio, SN, in decibels.
The function is error = 20 × log(1 + 10 For example, if the UUT ACPR is −62 dB and the measurement floor is −82 dB, the SN is 20 dB and the error due
to adding the analyzer distortion to that of the UUT is 0.83 dB.

c. As in footnote b, the specified ACPR accuracy applies if the ACPR measured substantially exceeds the analyzer
dynamic range at the specified offset. When this condition is not met, there are additional errors due to the addition of analyzer spectral components to UUT spectral components. Unlike the situation in footnote tral components from the analyzer will be non-coherent with the components from the UUT. Therefore, the errors
add in a power sense. The error is a function of the signal (UUT ACPR) to noise (analyzer ACPR dynamic range limitation) ratio, SN, in decibels.
The function is error = 10 × log(1 + 10 For example, if the UUT ACPR is 75 dB and the measurement floor is 85 dB, the SN ratio is 10 dB and the error
due to adding the analyzer's noise to that of the UUT is 0.41 dB.

a. The dynamic range specification 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 measure-
ment settings include 30 kHz RBW.
b. This dynamic range specification applies for the optimum mixer level, which is about 16 dBm. Mixer level is
defined to be the average input power minus the input attenuation.
c. The sensitivity is specified with 0 dB input attenuation. It represents the noise limitations of the analyzer. 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 offset s 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 analyzer. See
“Amplitude Accuracy and Range” on page 19 for more information. The numbers shown are for 0 - 3.0 GHz, with
attenuation set to 10 dB.

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 density 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
29.
d. 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 dB.

a. This does not include the effect of system noise floor. This error is a function of the signal (phase noise
of the DUT) to noise (analyzer noise floor due to phase noise and thermal noise) ratio, SN, in decibels.
The function is: error = 10 × log(1 + 10
SN/10
) For example, if the phase noise being measured is 10 dB above the measurement floor, the error due to adding the analyzer’s noise to the UUT is 0.41 dB.
b. Offset frequency errors also add amplitude errors. See the Offset frequency section, below. c. The phase noise density accuracy is derived from warranted analyzer specifications. It applies with
default settings and a 0 dBm carrier at 1 GHz. Most notable about the default settings is that the Over­drive (in the advanced menu of the Meas Setup menu) is set to Off.
d. The accuracy of an RMS marker such as “RMS degrees” is a fraction of the readout. That fraction, in per-
cent, depends on the phase noise accuracy, in dB, and is given by 100 × (10
PhaseNoiseDensityAccuracy / 20
1). For example, with +0.30 dB phase noise accuracy, and with a marker reading out 10 degrees RMS, the accuracy of the marker would be +3.5% of 10 degrees, or +0.35 degrees.

a. The figures given in the table are for the uncertainty added by the CXA Signal Analyzer instrument
only. To compute the total uncertainty for your noise figure measurement, you need to take into account other factors including: DUT NF, Gain and Match, Instrument NF, Gain Uncertainty and Match; Noise source ENR uncertainty and Match. The computations can be performed with the uncertainty calculator included with the Noise Figure Measurement Personality. Go to Mode Setup then select Uncertainty Calculator. Similar calculators are also available on the Agilent web site; go to http://www.agilent.com/find/nfu.
b. Uncertainty performance of the instrument is nominally the same in this frequency range as in the
higher frequency range. However, performance is not warranted in this range. There is a paucity of available noise sources in this range, and the analyzer has poorer noise figure, leading to higher uncertainties as computed by the uncertainty calculator.
c. “Instrument Uncertainty” is defined for noise figure analysis as uncertainty due to relative amplitude
uncertainties encountered in the analyzer when making the measurements required for a noise figure computation. The relative amplitude uncertainty depends on, but is not identical to, the relative display scale fidelity, also known as incremental log fidelity. The uncertainty of the analyzer is multiplied within the computation by an amount that depends on the Y factor to give the total uncertainty of the noise figure or gain measurement. See Agilent App Note 57-2, literature number 5952-3706E for details on the use of this specification. Jitter (amplitude variations) will also affect the accuracy of results. The standard deviation of the measured result decreases by a factor of the square root of the Resolution Bandwidth used and by the square root of the number of averages. This application uses the 4 MHz Resolution Bandwidth as default since this is the widest bandwidth with uncompromising accuracy.

the higher frequency range. However, performance is not warranted in this range. There is a paucity of available noise sources in this range, and the analyzer has poorer noise figure, lead­ing to higher uncertainties as computed by the uncertainty calculator.

a. The Noise Figure Uncertainty Calculator requires the parameters shown in order to calculate the total
uncertainty of a Noise Figure measurement.
b. Nominally, the noise figure of the spectrum analyzer is given by
NF = D (K L + N B)
where D is the DANL (displayed average noise level) specification, K is kTB (173.98 dB in a 1 Hz bandwidth at 290 K) L is 2.51 dB (the effect of log averaging used in DANL verifications) N is 0.24 dB (the ratio of the noise bandwidth of the RBW filter with which DANL is specified to an ideal noise bandwidth) B is ten times the base-10 logarithm of the RBW (in hertz) in which the DANL is specified. B is 0 dB for the 1 Hz RBW. The actual NF will vary from the nominal due to frequency response errors.

7 VXA Measurement Application

This chapter contains specifications for the VXA 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.
Specifications
These specifications summarize the performance for the CXA Signal Analyzer and apply to the VXA measurement application inside the analyzer. Unless stated otherwise, these are typical values, not warranted. Please refer to the signal analyzer specification guide for spectrum analysis performance.
