Keysight X-Series MXE EMI Receiver N9038B Specification Guide
1 Keysight MXE EMI Receiver
This chapter contains the specifications for the EMI receiver. The specifications and characteristics for the measurement applications and options are covered in the chapters that follow.

Keysight MXE EMI Receiver Definitions and Requirements
Definitions and Requirements
This book contains EMC receiver 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 (2) 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 receiver to meet its specifications. � The receiver 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 receiver 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 receiver 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 receiver 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.

Mode" column), the desired 1st LO harmonic is higher than the tuned frequency by the 1st IF (5.1225 GHz for band 0, 322.5 MHz for all other bands).

Keysight MXE EMI Receiver Frequency and Time
c. In the band overlap regions, for example, 3.5 to 3.6 GHz, the receiver may use either band for measurements, in this example Band 0 or Band 1. The receiver 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 receiver 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 receiver 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 receiver scans 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 8.4 GHz" represent nominal performance from 3.5 to 3.6 GHz, and warranted performance from 3.6 to 8.4 GHz.

a. For periods of one year or more. b. Calibration accuracy depends on how accurately the frequency standard was adjusted to 10 MHz. If the adjust-
ment procedure is followed, the calibration accuracy is given by the specification "Achievable Initial Calibration Accuracy." c. The specification applies after the receiver has been powered on for four hours. 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 Calibration 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. 4) Settability f. N is the LO multiplication factor.

Example for EMCd
�0.0032% (nominal)
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 set 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 receiver can be exceptionally good. As an example, Keysight has characterized the accuracy of a span commonly used for Electro-Magnetic Compatibility (EMC) testing using a source frequency locked to the receiver. 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 receiver 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. 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 receiver 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 receiver: 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 receiver 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. 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 above 18 GHz are prone to additional response errors due to modes in the Type-N connector used. 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 � [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 frequency, 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.
g. The Frequency Response with the RF Preselector on is verified at the analyzer center frequency in zero span. When the RF Preselector is a fixed filter (for frequencies up through 30 MHz), the effect of the RF Preselector is included in this Frequency Response specification. When the RF Preselector is a tracking filter, its effect at analysis frequencies away from the center frequency, such as can be measured with FFT-based measurements, can be significant but is not included in this expression of Frequency Response. The nominal response of the RF Preselector relative to its response at the center frequency is �20� log ((f/f0)2+1), where f0 in this equation is half of the �6 dB bandwidth of the RF preselector filter.

a. Signal frequencies above 18 GHz are prone to additional response errors due to modes in the Type-N connector used. With the use 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�.
b. The listed performance is the standard deviation of the phase deviation relative to the mean phase deviation from a linear phase condition, where the rms is computed across the span shown and over the range of center frequencies shown.

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. 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. When using Time Domain scan, only the 95th percentile specification applies.

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. 3 = 3(20dB)log(1+10�((S/N+ 3dB)/ 20dB)) 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. 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 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 attenuation = 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 �0.025 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.

Keysight N9038B MXE Specification Guide

e. Errors at high mixer levels will nominally 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, ex). 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.
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 receiver 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 change in an on-screen signal.
b. Specified at 1 kHz RBW with 100 kHz tone spacing. Time Domain scan nominal values verified using a 1 kHz RBW with 50 MHz 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 earlier receivers in a way that makes this receiver more flexible. In other receivers, the RL controlled how the measurement was performed as well as how it was displayed. Because the logarithmic amplifier in these receivers had both range and resolution limitations, this behavior was necessary for optimum measurement accuracy. The logarithmic amplifier in this receiver, however, is implemented digitally such that the range and resolution greatly exceed other instrument limitations. Because of this, the receiver 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. When using Time Domain scan, all indicated values shown here are nominal values. e. Mixer power level (dBm) = input power (dBm) - input attenuation (dB) (�9 dB for RF Input 2). f. RF Input 2 operates to 1 GHz. The 1 dB gain compression is nominally 9 dB higher.

a. Mixer power level (dBm) = input power (dBm) - input attenuation (dB) (�9 dB for RF Input 2). b. The ADC clipping level declines at low frequencies (below 50 MHz) when the LO feed through (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. The nominal performance 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 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 changes 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 14; 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.
d. Analyzer-contributed phase noise at the low levels of this offset requires advanced verification techniques because broadband noise would otherwise cause excessive measurement error. Keysight uses a high level low phase noise CW test signal and sets the input attenuator so that the mixer level will be well above the normal top-of-screen level (-10 dBm) but still well below the 1 dB compression level. This improves dynamic range (carrier to broadband noise ratio) at the expense of amplitude uncertainty due to compression of the phase noise sidebands of the analyzer. (If the mixer level were increased to the "1 dB Gain Compression Point," the compression of a single sideband is specified to be 1 dB or lower. At lower levels, the compression falls off rapidly. The compression of phase noise sidebands is substantially less than the compression of a single-sideband test signal, further reducing the uncertainty of this technique.) Keysight also measures the broadband noise of the analyzer without the CW signal and subtracts its power from the measured phase noise power. The same techniques of overdrive and noise subtraction can be used in measuring a DUT, of course.

a. The effect of scale fidelity on the ratio of two powers is called the relative scale fidelity. The scale fidelity specified in the Amplitude section is an absolute scale fidelity with �35 dBm at the input mixer as the reference point. The relative scale fidelity is nominally only 0.01 dB larger than the absolute scale fidelity.
b. See Amplitude Accuracy and Range section. c. See Frequency and Time section. d. Expressed in decibels. 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 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 measuring 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 - (-19 dBm). For example, if the average input power is -7 dBm, set the attenuation to 12 dB. This specification applies for the normal 10 dB peak-to-average ratio (at 0.01% probability) for Test Model 1. Note that, if the mixer level is set to 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 optimize the dynamic range, and assuming that the analyzer and UUT distortions are incoherent. When the errors from the UUT and the analyzer are incoherent, optimizing dynamic range is equivalent to minimizing the contribution of analyzer noise and distortion to accuracy, though the higher mixer level increases the display scale fidelity errors. This incoherent addition case is commonly used in the industry and can be useful for comparison of analysis equipment, but this incoherent addition model is rarely justified. This derived accuracy specification is based on a mixer level of -14 dBm.

l. Keysight 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, Keysight only gives a typical result. More than 80% of prototype instruments met this "typical" specification; the factory test line limit is set commensurate with an on-going 80% yield to this typical. 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.
m. ML is Mixer Level, which is defined to be the input signal level minus attenuation. n. All three production units hand-measured had performance better than 88 dB with a test signal even better
than the "near-ideal" one used for statistical process control in production mentioned in the footnotel above. Therefore, this value can be considered "Nominal" not "Typical" by the definitions used within this document. These observations were done near 2 GHz because that is a common W-CDMA operating region in which the analyzer third-order dynamic range is near its best. o. 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 the filter in this instrument. The effect of the RRC filter and the effect of the RBW used in the measurement interact. The analyzer compensates the shape of the RRC filter to accommodate the RBW filter. The effectiveness of this compensation is summarized 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. Coher = no means that the specified accuracy only applies when the distortions of the device under test are not coherent with the third-order distortions of the analyzer. Incoherence is often the case with advanced multi-carrier amplifiers built with compensations and predistortions that mostly eliminate coherent third-order effects in the amplifier.
b. Optimum mixer level (MLOpt). The mixer level is given by the average power of the sum of the four carriers minus the input attenuation.

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 -18 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 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 analyzer. See "Absolute Amplitude Accuracy" on page 35 for more information. The numbers shown are for 0 to 3.6 GHz, with attenuation set to 10 dB.

Examplef
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 44.
d. DANL is specified with the IF Gain set to High, which is the best case for DANL but not for Clipping-to-noise dynamic range. The core specifications "Displayed Average Noise Level" on page 44, 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 clipping level is -138.2 dBfs/Hz.

a. The level of these spurs is not warranted. The relationship between the spurious response and its excitation is described in order to make it easier for the user to distinguish whether a questionable response is due to these mechanisms. f is the apparent frequency of the spurious signal, 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.
c. Mixer Level = Input Level - Input Attenuation.

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 above 18 GHz are prone to additional response errors due to modes in the Type-N connector used. 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�. The effect of these modes is not included within the Max Error specification. The effect on the RMS is negligible, except to note that the modes make the ratio of worst-case error to RMS error unusually high.
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 the 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. 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 frequency, 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.
g. For information on the microwave preselector which affects the passband for frequencies above 3.6 GHz, see "Microwave Preselector Bandwidth" on page 26.

Information See specifications in this chapter. See specifications in this chapter. There are three effects of the use of Option B85/B1X on spurious responses. Most of the warranted elements of the Spurious Responses on page 52 still apply without changes, but the revised-for-B85/B1X table 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, spurious-free dynamic range specifications are given in this chapter, as well as IF Residuals. See specifications in this chapter. This bandwidth option can create additional TOI products to those that are created by other instrument circuitry. These products do not behave with typical analog third-order behavior, and thus cannot be specified in the same manner. Nominal performance statements are given in this chapter, but they cannot be expected to decrease as the cube of the voltage level of the signals. The performance of the analyzer will degrade by an unspecified extent when using wideband analysis. This extent is not substantial enough to justify statistical process control. Nominally 0.5 dB degradation from base instrument absolute amplitude accuracy. (Refer to Absolute Amplitude Accuracy on page 35.) Specifications on this bandwidth only apply with center frequencies of 100 MHz and higher.

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 above 18 GHz are prone to response errors due to modes in the Type-N connector. Only analyzers with frequency Option 526 that do not also have input connector Option C35 will have these modes.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 listed performance is the rms of the amplitude deviation from the mean amplitude response of a span/CF combination. 50% of the combinations of prototype instruments, center frequencies and spans had performance better than the listed values.
d. The passband shape will be greatly affected by the microwave preselector. See "Microwave Preselector Bandwidth" on page 26.

b. The noise level is specified in the table above, "Displayed Average Noise Level." Please consider these details and additional information: DANL is, by Keysight and industry practice, specified with log averaging, which reduces the measured noise level by 2.51 dB. It is specified for a 1 Hz resolution bandwidth, which will nominally have a noise bandwidth of 1.056 Hz. Therefore, the noise density is 2.27 dB above the DANL.

b. Preamp Gain directly affect distortion and noise performance, but it also affects the range of levels that are free of final IF overload. The user interface has a designed relationship between input attenuation and reference level to prevent on-screen signal levels from causing final IF overloads. That design is based on the maximum preamp gains shown. Actual preamp gains are modestly lower, by up to nominally 5 dB for frequencies from 100 kHz to 3.6 GHz, and by up to nominally 10 dB for frequencies from 3.6 to 26.5 GHz.

a. Large signals, even at frequencies not shown on the screen, can cause the receiver 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 change in an on-screen signal.

b. Specified at 1 kHz RBW with 100 kHz tone spacing. Time Domain scan nominal values verified using a 1 kHz RBW with 50 MHz 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 earlier receivers in a way that makes this receiver more flexible. In other receivers, the RL controlled how the measurement was performed as well as how it was displayed. Because the logarithmic amplifier in these receivers had both range and resolution limitations, this behavior was necessary for optimum measurement accuracy. The logarithmic amplifier in this receiver, however, is implemented digitally such that the range and resolution greatly exceed other instrument limitations. Because of this, the receiver 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. When using Time Domain scan, all indicated values shown here are nominal values. e. Mixer power level (dBm) = input power (dBm) - input attenuation (dB) (�9 dB for RF Input 2). f. RF Input 2 operates to 1 GHz. The 1 dB gain compression is nominally 9 dB higher. g. Total power at the preamp (dBm) = total power at the input (dBm) � input attenuation (dB).

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. 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. When using Time Domain scan, only the 95th percentile specification applies.
b. Same settings as footnote a, except that the signal level at the preamp input is �40 to �80 dBm. Total power at the preamp (dBm) = total power at the input (dBm) minus input attenuation (dB).
c. Same settings as footnote a, except that the signal level at the preamp input is �40 to �80 dBm. Total power at the preamp (dBm) = total power at the input (dBm) minus input attenuation (dB) � 9 dB.

a. Signal frequencies above 18 GHz are prone to response errors due to modes in the Type-N connector used. 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. For FFT based measurements, Frequency Response errors are more complicated. One case is where the input signal is at the center frequency of the FFT measurement. In this case, the Frequency Response errors are given by this table. The total absolute amplitude accuracy is given by the combination of the absolute amplitude accuracy at 50 MHz with the Frequency Response from this table. The other case is when the input signal is not at the center frequency of the FFT measurement. In this case, the total frequency response error is computed by adding the RF flatness errors of this table to the IF Frequency Response. The total absolute amplitude accuracy is given by the combination of the absolute amplitude accuracy at 50 MHz with this total frequency response error. An additional error source, the relative error in switching between swept and FFT-based measurements, is nominally �0.01 dB. The effect of this relative error on absolute measurements is included with the "Absolute Amplitude Accuracy" specifications.
c. Specifications apply with DC coupling at all frequencies. With AC coupling, specifications apply at frequencies 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.

a. This statement on the improvement in DANL is based on the accuracy of the fit of the noise floor model to the measured values of that noise. This measure of the performance correlates well with improvement versus frequency. The improvement actually measured and specified in "Examples of Effective DANL" usually meet these limits as well, but not with the confidence in some cases. Does not apply to Time Domain scan.
b. DANL of the preamp is specified with a 50 source impedance. Like all amplifiers, the noise varies with the source impedance. When NFE compensates for the noise with an ideal source impedance, the variation in the remaining noise level with the actual source impedance is greatly multiplied in a decibel sense.

a. The dynamic range is given by this computation: -10 dBm - DANL - 10�log(RBW) where DANL is the displayed average noise level specification, normalized to 1 Hz RBW, and the RBW used in the measurement is in hertz units. The dynamic range can be increased by reducing the RBW at the expense of increased sweep time.
b. The following footnotes discuss the biggest contributors to amplitude accuracy. c. One amplitude accuracy contributor is the linearity with which amplitude levels are detected by the analyzer.
This is called "scale fidelity" by most spectrum analyzer users, and "dynamic amplitude accuracy" by most network analyzer users. This small term is documented in the Amplitude section of the Specifications Guide. It is negligibly small in most cases. d. The amplitude accuracy versus frequency in the source and the analyzer can contribute to amplitude errors. This error source is eliminated when using normalization in low band (0 to 3.6 GHz). In high band the gain instability of the YIG-tuned microwave preselector in the analyzer keeps normalization errors nominally in the 0.25 to 0.5 dB range. e. In the worst case, the center frequency of the YIG-tuned microwave preselector can vary enough to cause very substantial errors, much higher than the nominal 0.25 to 0.5 dB nominal errors discussed in the previous footnote. In this case, or as a matter of good practice, the microwave preselector should be centered. See the user's manual for instructions on centering the microwave preselector. f. VSWR interaction effects, caused by RF reflections due to mismatches in impedance, are usually the dominant error source. These reflections can be minimized by using 10 dB or more attenuation in the analyzer, and using well-matched attenuators in the measurement configuration.

a. The errors in the output can be described as offset and gain errors. An offset error is a constant error, expressed as a fraction of the full-scale output voltage. The gain error is proportional to the output voltage. Here's an example. The reference level is -10 dBm, the scale is log, and the scale is 5 dB/division. Therefore, the top of the display is -10 dBm, and the bottom is -60 dBm. Ideally, a -60 dBm signal gives 0 V at the output, and -10 dBm at the input gives 1 V at the output. The maximum error with a -60 dBm input signal is the offset error, �1% of full scale, or �10 mV; the gain accuracy does not apply because the output is nominally at 0 V. If the input signal is -20 dBm, the nominal output is 0.8 V. In this case, there is an offset error (�10 mV) plus a gain error (�1% of 0.8 V, or �8 mV), for a total error of �18 mV.

a. There is an interruption in the tracking of the video output before each sweep. During this interruption, the video output holds instead of tracks for a time period given by approximately 1.8/RBW.
b. There is an interruption in the tracking of the video output during alignments. During this interruption, the video output holds instead of tracking the envelope of the RF input signal. Alignments may be set to prevent their interrupting video output tracking by setting Auto Align to Off.
c. Setting Auto Align to Off usually results in a warning message soon thereafter. Setting Auto Align to Partial results in many fewer and shorter alignment interruptions, and maintains alignments for a longer interval.
d. If video output interruptions for Partial alignments are unacceptable, setting the analyzer to External Trigger without a trigger present can prevent these from occurring, but will prevent there being any on-screen updating. Video output is always active even if the analyzer is not sweeping.
e. Compatibility with the HP/Keysight 8560 and 8590 families, and the ESA and PSA, is similar in most respects. f. The HP 8566 family did not have alignments and interruptions that interrupted video outputs, as discussed
above. g. Early HP 8566-family spectrum analyzers had a 140 output impedance; later ones had 190. The specifica-
tion was <475. The Analog Out port has a 50 impedance if the analyzer has Option DP2, or MPB. Otherwise, the Analog Out port impedance is nominally 140. h. The HP 8566 family had LL (lower left) and UR (upper right) controls that could be used to calibrate the levels from the video output circuit. These controls are not available in this option. i. The delay between the RF input and video output shown in Delay on page 153 is much higher than the delay in the HP 8566 family spectrum analyzers. The latter has a delay of approximately 0.554/RBW + 0.159/VBW.

a. The figures given in the table are for the uncertainty added by the X-Series 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 Keysight web site; go to http://www.keysight.com/find/nfu. b. Uncertainty performance of the instrument is nominally the same in this frequency range as in the higher fre-
quency 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. At the highest frequencies, especially above 40 GHz, the only Keysight Supra-26-GHz noise source, the 346CK01, often will not have enough ENR to allow for the calibration operation. Operation with "Internal Cal" is almost as accurate as with normal calibration, so the inability to use normal calibration does not greatly impact usefulness. Also, if the DUT has high gain, calibration has little effect on accuracy. In those rare cases when normal calibration is required, the Noisecom NC5000 series and the NoiseWave NW346V do have adequate ENR for calibration. d. "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 Keysight 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 because this is the widest bandwidth with uncompromised accuracy.

a. "Instrument Uncertainty" is defined for gain measurements as uncertainty due to relative amplitude uncertainties encountered in the analyzer when making the measurements required for the gain computation. See Keysight 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 uncompromised accuracy. Under difficult conditions (low Y factors), the instrument uncertainty for gain in high band can dominate the NF uncertainty as well as causing errors in the measurement of gain. These effects can be predicted with the uncertainty calculator.
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. For frequencies above 3.6 GHz, the analyzer uses a YIG-tuned filter (YTF) as a microwave preselector, which adds uncertainty to the gain. When the Y factor is small, such as with low gain DUTs, this uncertainty can be greatly multiplied and dominate the uncertainty in NF (as the user can compute with the Uncertainty Calculator), as well as impacting gain directly. When the Y factor is large, the effect of IU of Gain on the NF becomes negligible. When the Y-factor is small, the non-YTF mechanism that causes Instrument Uncertainty for Gain is the same as the one that causes IU for NF with low ENR. Therefore, we would recommend the following practice: When using the Uncertainty Calculator for noise figure measurements above 3.6 GHz, fill in the IU for Gain parameter with the sum of the IU for NF for 4 - 6.5 dB ENR sources and the shown "additional" IU for gain for this frequency range. When estimating the IU for Gain for the purposes of a gain measurement for frequencies above 3.6 GHz, use the sum of IU for Gain in the 0.01 to 3.6 GHz range and the "additional" IU shown.You will find, when using the Uncertainty Calculator, that the IU for Gain is only important when the input noise of the spectrum analyzer is significant compared to the output noise of the DUT. That means that the best devices, those with high enough gain, will have comparable uncertainties for frequencies below and above 3.6 GHz. The additional uncertainty shown is that observed to be met in 95% of the frequency/instrument combinations tested with 95% confidence. It applies within five minutes of a calibration. It is not warranted.

See "DANL and Indicated Noise Improvement with Noise Floor Extension" on page 59.
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 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. c. 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. d. Analyzers with NFE (Noise Floor Extension) use that capability in the Noise Figure Measurement Application to allow "Internal Cal" instead of user calibration. With internal calibration, the measurement is much better than an uncalibrated measurement but not as good as with user calibration. Calibration reduces the effect of the analyzer noise on the total measured NF. With user calibration, the extent of this reduction is computed in the uncertainty calculator, and will be on the order of 16 dB. With internal calibration, the extent of reduction of the effective noise level varies with operating frequency, its statistics are given on the indicated page. It is usually about half as effective as User Calibration, and much more convenient. For those measurement situations where the output noise of the DUT is 10 dB or more above the instrument input noise, the errors due to using an internal calibration instead of a user calibration are negligible.

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 for the non-overdrive case is derived from warranted analyzer specifications.
It applies whenever there is no overdrive. Overdrive occurs only for offsets of 1 MHz and greater, with signal input power greater than -10 dBm, and controls set to allow overdrive. The controls allow overdrive if the "Overdriv (MAtn)" control is set to Auto (in the Meas Setup > Advanced menu) and the "Pre-Adjust for Min Clip" control (in the Amplitude menu under Attenuation) is not set to Off, and the Electronic Attenuator is licensed and set to On. The controls also allow overdrive if the "Overdriv (MAtn)" control is set to On. To prevent overdrive in all cases, set the Overdriv control to Auto and set the Electronic Attenuator (if licensed) to Off. d. The accuracy of an RMS marker such as "RMS degrees" is a fraction of the readout. That fraction, in percent, depends on the phase noise accuracy, in dB, and is given by 100 � (10PhaseNoiseDensityAccuracy / 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 frequency offset error in octaves causes an additional amplitude accuracy error proportional to the product of the frequency error and slope of the phase noise. For example, a 0.01 octave frequency error combined with an 18 dB/octave slope gives 0.18 dB additional amplitude error.
