Keysight PXE 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 = 0� to 55�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.

b. N is the LO multiplication factor. For negative mixing modes (as indicated by the "-" in the "Harmonic Mixing 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).
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. 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. For periods of one year or more. c. N is the LO multiplication factor. d. The specification applies after the receiver has been powered on for four hours. e. 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. f. 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

Single detector onlyc
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 120 kHz for the 0.0.10% � span term, for a total of 175 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 20 kHz of error (0.10%) due to the span and 200 kHz error (5%) due to the RBW. For this non-autocoupled RBW, the RBW error is nominally 30%, or 1200 kHz.
b. Horizontal resolution is due to the marker reading out one of the 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. 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.

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�.

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. The effect of the RF Preselector is included in this Frequency Response specification. .

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.

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. 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.

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.

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. This statement on the improvement in DANL is based on the statistical observations of the error in the effective noise floor after NFE is applied. That effective noise floor can be a negative or a positive power at any frequency. These 95th percentile values are based on the absolute value of that effective remainder noise power.
b. Unlike other 95th percentiles, these table values do not include delta environment effects. NFE is aligned in the factory at room temperature. For best performance, in an environment that is different from room temperature, such as an equipment rack with other instruments, we recommend running the "Characterize Noise Floor" operation after the first time the analyzer has been installed in the environment, and given an hour to stabilize.
c. NFE does not apply to the low frequency sensitivity. At frequencies below about 0.5 MHz, the sensitivity is dominate by phase noise surrounding the LO feedthrough. The NFE is not designed to improve that performance. At frequencies between 0.5 and 10 MHz the NFE effectiveness increases from nearly none to near its maximum
d. For RF Preselector path, NFE does not apply at frequencies below 100 kHz. At frequencies between 100 kHz and 150 kHz, the NFE effectiveness is not measured, but is designed to be nominally the same as frequencies above 150 kHz.

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.

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. 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 34 for more information. The numbers shown are for 0 to 3.6 GHz, with attenuation set to 10 dB.

a. This specification is defined to be the ratio of the clipping level (also known as "ADC Over Range") to the noise density. In decibel units, it can be defined as clipping_level [dBm] - noise_density [dBm/Hz]; the result has units of dBfs/Hz (fs is "full scale").
b. The noise density depends on the input frequency. It is lowest for a broad range of input frequencies near the center frequency, and these specifications apply there. The noise density can increase toward the edges of the span. The effect is nominally well under 1 dB.
c. The primary determining element in the noise density is the "Displayed Average Noise Level" on page 48. 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 48, 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.

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.

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.

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

Information See specifications in this chapter. See specifications in this chapter. There are three effects of the use of Option B40 on spurious responses. Most of the warranted elements of the "Spurious Responses" on page 56 still apply without changes, but the revised-version of the table on page 56, modified to reflect the effect of Option B40, is shown in its place in this chapter. The image responses part of that table have the same warranted limits, but apply at different frequencies as shown in the table. The "higher order RF spurs" line is slightly degraded. Also, 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 34.) Specifications on this bandwidth only apply with center frequencies of 30 MHz and higher.

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. For best possible sensitivity, the LNA can be turned on together with the Internal Preamp, although when operating both preamps together, the user should note that the TOI (distortion) specifications are impacted.
b. Preamplifier Gain is the combined gain from the Preamp and LNA. It directly affects 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 preamplifier gains shown. Actual amplifier gains are modestly lower, by up to nominally 5 dB.
c. If both the Preamp and LNA are set to ON by the user and the EMI Receiver is then tuned below 3.6 GHz, the Preamp will automatically be turned off by the instrument firmware.

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.

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. 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.

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 at10 MHz at the temperature extreme. The effect at 20 to 50 MHz is negligible, but not warranted.
d. When the notch filter is selected, the specifications between 2.3 to 2.6 GHz is not applicable. e. Specification for frequencies > 3.5 GHz apply for sweep rates 100 MHz/ms. f. Microwave preselector centering applied.

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.

Options P03, P08, P26, P44 - Preamplifiers Other Preamp Specification
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 at10 MHz at the temperature extreme. The effect at 20 to 50 MHz is negligible, but not warranted.
d. Specification for frequencies > 3.5 GHz apply for sweep rates 100 MHz/ms. e. Microwave preselector centering applied. f. When the notch filter is selected, the specifications between 2.3 to 2.6 GHz is not applicable.

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 fre-quency. 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.
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.
c. NFE does not apply to the low frequency sensitivity. At frequencies below about 0.5 MHz, the sensitivity is dominate by phase noise surrounding the LO feedthrough. The NFE is not designed to improve that performance. At frequencies between 0.5 and 10 MHz the NFE effectiveness increases from nearly none to near its maximum
d. For RF Preselector path, NFE does not apply at frequencies below 100 kHz. At frequencies between 100 kHz and 150 kHz, the NFE effectiveness is not measured, but is designed to be nominally the same as frequencies above 150 kHz.

a. This statement on the improvement in DANL is based on the statistical observations of the error in the effective noise floor after NFE is applied. That effective noise floor can be a negative or a positive power at any frequency. These 95th percentile values are based on the absolute value of that effective remainder noise power.

b. Unlike other 95th percentiles, these table values do not include delta environment effects. NFE is aligned in the factory at room temperature. For best performance, in an environment that is different from room temperature, such as an equipment rack with other instruments, we recommend running the "Characterize Noise Floor" operation after the first time the analyzer has been installed in the environment, and given an hour to stabilize.
c. For RF Preselector path, NFE does not apply at frequencies below 100 kHz. At frequencies between 100 kHz and 150 kHz, the NFE effectiveness is not measured, but is designed to be nominally the same as frequencies above 150 kHz.

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 B40, 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 183 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.

11 Analog Demodulation Measurement Application
Additional Definitions and Requirements
This chapter contains specifications for the N9063EM0E Analog Demodulation Measurement Application.
The warranted specifications shown apply to Band 0 operation (up to 3.6 GHz), unless otherwise noted, for all analyzers. The application functions, with nominal (non-warranted) performance, at any frequency within the frequency range set by the analyzer frequency options (see table). In practice, the lowest and highest frequency of operation may be further limited by AC coupling; by "folding" near 0 Hz; by DC feedthrough; and by Channel BW needed. Phase noise and residual FM generally increase in higher bands. Warranted specifications shown apply when Channel BW 1 MHz, unless otherwise noted. (Channel BW is an important user-settable control.) The application functions, with nominal (non-warranted) performance, at any Channel BW up to the analyzer's bandwidth options (see table). The Channel BW required for a measurement depends on: the type of modulation (AM, FM, PM); the rate of modulation; the modulation depth or deviation; and the spectral contents (e.g. harmonics) of the modulating tone. Many specifications require that the Channel BW control is optimized: neither too narrow nor too wide. Many warranted specifications (rate, distortion) apply only in the case of a single, sinusoidal modulating tone without excessive harmonics, non-harmonics, spurs, or noise. Harmonics, which are included in most distortion results, are counted up to the 10th harmonic of the dominant tone, or as limited by SINAD BW or post-demod filters. Note that SINAD will include Carrier Frequency Error (the "DC term") in FM by default; it can be eliminated with a HPF or Auto Carrier Frequency feature. Warranted specifications apply to results of the software application; the hardware demodulator driving the Analog Out line is described separately. Warranted specifications apply over an operating temperature range of 20� to 30�C; and mixer level -23 to -18 dBm (mixer level = Input power level � Attenuation). Additional conditions are listed at the beginning of the FM, AM, and PM sections, in specification tables, or in footnotes. See "Definitions of terms used in this chapter" on page 186.

Let Psignal (S) = Power of the signal; Pnoise (N) = Power of the noise; Pdistortion (D) = Power of the harmonic distortion (PH2+ PH3 + ...+ P where Hi is the ith harmonic up to i =10); Ptotal = Total power of the signal, noise and distortion components.

Definition (Ptotal � Psignal)1/2 / (Ptotal)1/2 � 100%

The approximation is per the implementations defined with the HP/Agilent/Keysight 8903A.
Pnoise must be limited to the bandwidth of the applied filters. The harmonic sequence is limited to the 10th harmonic unless otherwise indicated. Pnoise includes all spectral energy that is not near harmonic frequencies, such as spurious signals, power line interference, etc.

a. The maximum Info BW indicates the maximum operational BW, which depends on the analysis BW option equipped with the analyzer. However, the demodulation specifications only apply to the Channel BW indicated in the following sections.
b. Sample rate is set indirectly by the user, with the Span and Channel BW controls (viewed in RF Spectrum). The Info BW (also called Demodulation BW) is based on the larger of the two; specifically, Info BW = max [Span, Channel BW]. The sample interval is 1/(1.25 � Info BW); e.g. if Info BW = 200 kHz, then sample interval is 4 us. The sample rate is 1.25 � Info BW, or 1.25 � max [Span, Channel BW]. These values are approximate, to estimate memory usage. Exact values can be queried via SCPI while the application is running. Acq Time (acquisition time) is set by the largest of 4 controls: Acq Time = max[2.0 / (RF RBW), 2.0 /(AF RBW), 2.2 � Demod Wfm Sweep Time, Demod Time]

a. ITU standards specify that CCIR-1k Weighted and CCIR Unweighted filters use Quasi-Peak-Detection (QPD). However, the implementation in N9063EM0E is based on true-RMS detection, scaled to respond as QPD. The approximation is valid when measuring amplitude of Gaussian noise, or SINAD of a single continuous sine tone (e.g. 1 kHz), with harmonics, combined with Gaussian noise. The results may not be consistent with QPD if the input signal is bursty, clicky, or impulsive; or contains non-harmonically related tones (multi-tone, intermods, spurs) above the noise level. Use the AF Spectrum trace to validate these assumptions. Consider using Agilent/Keysight U8903A Audio Analyzer if true QPD is required.
b. The Signaling Notch filter does not visibly affect the AF Spectrum trace.

Analog Demodulation Measurement Application Analog Out
Analog Out
The "Analog Out" connector (BNC) is located at the analyzer's rear panel. It is a multi-purpose output, whose function depends on options and operating mode (active application). When the N9063EM0E Analog Demod application is active, this output carries a voltage waveform reconstructed by a real-time hardware demodulator (designed to drive the "Demod to Speaker" function for listening). The processing path and algorithms for this output are entirely separate from those of the N9063EM0E application itself; the Analog Out waveform is not necessarily identical the application's Demod Waveform. Condition of "Open Circuit" is assumed for all voltage terms such as "Output range".

a. For AM, the output is the "RF envelope" waveform. For FM, the output is proportional to frequency deviation; note that Carrier Frequency Error (a constant frequency offset) is included as a deviation from the analyzer's tuned center frequency, unless a HPF is used. For PM, the output is proportional the phase-deviation; note that PM is limited to excursions of �pi, and requires a HPF on to enable a phase-ramp-tracking circuit. Most controls in the N9063C application do not affect Analog Out. The few that do are: -choice of AM, FM, or PM (FM Stereo not supported) - tuned Center Freq -Channel BW (affects IF filter, sample rate, and FM scaling) -some post-demod filters and de-emphasis (the hardware demodulator has limited filter choices; it will attempt to inherit the filter settings in the app, but with constraints and approximations)
b. For AM, the reference "unmodulated" carrier level is determined by a single "invisible" power measurement, of 2 ms duration, taken at setup. "Setup" occurs whenever a core parameter is changed, such as Center Frequency, modulation type, Demod Time, etc. Ideally, the RF input signal should be un-modulated at this time. However, if the AM modulating (audio) waveform is evenly periodic in 2 ms (i.e. multiples of 500 Hz, such as 1 kHz), the reference power measurement can be made with modulation applied. Likewise, if the AM modulating period is very short compared to 2ms (e.g. >5000 Hz), the reference power measurement error will be small.
