Keysight CXA Signal Analyzer

Specification Guide

1 Keysight CXA Signal Analyzer

This chapter contains the specifications for the core signal analyzer. The specifications and characteristics for the measurement applications and options are covered in the chapters that follow.

Keysight 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 =

0 to 55°C, also referred to as "Full temperature range" or "Full range", unless otherwise noted.

• 95th percentile values indicate the breadth of the population (»2s) 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.

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 (Option 513/526 only).

• 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. If Auto Align is set to Light, performance is not warranted, and nominal performance will degrade to become a factor of 1.4 wider

for any specification subject to alignment, such as amplitude tolerances.

Certification

Keysight Technologies certifies that this product met its published specifications at the time of shipment from the factory. Keysight 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.

a. N is the LO multiplication factor. b. In the band overlap regions, take option 513/526 for example, 2.95 to 7.5 GHz, the analyzer may use either band for measure-

ments, 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 7.5 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 to 7.5 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 Band0/Band 1 crossing is this: The specifications given in the “Specifications” column which are described as “2.95 to 7.5 GHz” represent nominal performance from 2.95 to 3.0 GHz, and warranted performance from 3.0 to 7.5 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 15 minutes. c. 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 the power is applied. The effect of

retracing is included within the “Achievable Initial Calibration Accuracy” term of the Accuracy equation. d. 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.

4) Settability

Frequency Readout Accuracy

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 domi-

nates, 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 auto-

coupled. 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 fac-

tory 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, Keysight has character-

ized 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

bandwid th 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. 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 bandwid th 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 designed to be 4.1:1. Verifying the selectivity with RBWs 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 Keysight 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. Signal frequencies between 18 and 26.5 GHz are prone to additional response errors due to modes in the Type-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. 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. Perfor-

mance is nominally three times better than the maximum error at most center frequencies. d. The specification does not apply for frequencies greater than 3.0 MHz from the center in FFT Widths of 7.2 to 8 MHz. e. 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 repre-

sentative 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 subset 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 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 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 organiza-

tion. 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. The nominal performance of the phase noise at center frequencies different than the one at which the specifica-

tions apply (1 GHz) depends on the center frequency, band and the offset. For low offset frequencies, 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 11; 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 optimization

PhNoise Opt) set to Best Close-in  Noise. Noise sidebands for higher offset frequencies, for example, 1 MHz, as

( shown apply with the phase noise optimization set to Best Wide-offset  Noise.

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.

Power Suite Measurements

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 .

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 prod-

ucts 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 nomi-

nally 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 ana-

lyzer are incoherent, optimizing dynamic range is equivalent to minimizing the contribution of analyzer noise and distor-

tion 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.

Keysight measures 10

requires a near-ideal signal, which is impractical for field and customer use. Because field verification is impractical, Key-

sight 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 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 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.

Method

ACPR Relative Accuracy

Offsets < 750 kHz

Offsets > 1.98 MHz

a. The RBW method measures the power in the adjacent channels within the defined resolution bandwidth. The noise band width 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 bandwid th measurement is equal to that integration bandwidth. For cdmaOne 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 b, though, the spectral 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 measurement 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 emis-

sion 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

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 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 30. 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. Large signals, even at frequencies not shown on the screen, can cause the analyzer to incorrectly measure 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

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. Mixer power level (dBm) = input power (dBm)  input attenuation (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.

excitation is described so the user can distinguish whether a questionable response is due to these mechanisms or is subject to the specifications in “Spurious Responses” in the core specifications. f is the apparent frequency of the spurious, fc is the measurement center frequency.

b. The spurious response specifications only apply with the preamp turned off. When the preamp is turned on, performance is

nominally the same as long as the mixer level is interpreted to be Mixer Level = Input Level  Input Attenuation  Preamp Gain

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. Signal frequencies between 18 and 26.5 GHz are prone to additional response errors due to modes in the Type-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. 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 cen-

ter 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 spec-

ifications include the effect of RF frequency response as well as IF frequency response at the worst case center frequency. Perfor-

mance is nominally three times better than the maximum error at most center frequencies. d. The specification does not apply for frequencies greater than 3.6 MHz from the center in FFT Widths of 7.2 to 8 MHz. e. 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 repre-

sentative of all center frequencies; the observation center frequency is not the worst case center frequency.

where, D is the DANL (displayed average noise level) specification (Refer to page 83 for DANL with Preamp),

K is kTB (.173.98 dBm 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. b. The effect of AC coupling is negligible for frequencies above 40 MHz. Below 40 MHz, DC coupling is recommended for the best

measurements. The instrument NF nominally degrades by 0.2 dB at 30 MHz and 1 dB at 10 MHz with AC coupling.
