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 GH z, the analyzer may use either band for measurements, in
this example Band 0 or Band 1. The analyzer gives preference to the band with the better overall specifications
(which is the lower numbered band for all frequencies below
26 GHz), but will choose the other band if doing so
is necessary to achieve a sweep having minimum band crossings. For example, with CF =
3.58 GHz, with a span
of 40 MHz or less, the analyzer uses Band 0, because the stop frequency is
3.6 GHz or less, allowing a span
without band crossings in the preferred band. If the span is between 40 and 160 MHz, the analyzer uses Band
1
because the start frequency is above 3.5 GHz, allowing the sweep to be done without a band crossing in Band
1
though the stop frequency is above 3.6 GHz, preventing a Band
0 sweep without band crossing. With a span
greater than 160 MHz, a band crossing will be required: the analyzer sweeps up to 3.6 GHz in Band
0; then exe-
cutes 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 alter-
nate band are not warranted in the band overlap region, but performance is nominally the same as those war-
ranted 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 neces-
sary 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” col-

d. Standby mode does not apply power to the oscillator . Therefore warm-up applies every time the power is

warm-up occurs. The effect of retracing is included within the “Achievable Initial Calibration Accuracy” term of
Frequency and Time 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 envi-
ronment 3) Retrace effects in both the calibration environment and the use environment due to turning the instrument power off.

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

c. Specifications apply to traces in most cases, but ther e 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. Spec-
points, the errors in excess of the bucket quantization limitation were negligible.
readout accuracy is 2% of RBW for RBWs from 1 Hz to 390 kHz, 4% of RBW from 430 kHz through
3 MHz (the
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 accu-
racy, compared to 300 kHz for the
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),
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 readin g 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

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 an alyzer can be exceptionally good. As an example, Key- sight has characterized the accuracy of a span commonly used for Electro-Magnetic Compatibility (EMC) testing using a source frequency locked to the analyzer. Ideally, this sweep would include EMC bands C and D and thus
sweep from 30 to 1000 MHz. Ideally, the analysis bandwidth would be
120 kHz at −6 dB, and the spacing of the
points would be half of this (60 kHz). With a start frequency of 30 MHz and a stop frequency of 1000.2 MHz and
a total of 16168 points, the spacing of points is ideal. The detector used was the Peak detector. The accuracy of
frequency readout of all the points tested in this span was with ±0.0032% of the span. A perfect analyzer with
this many points would have an accuracy of ±0.0031% of span. Thus, even with this large number of display

Frequency and Time b. The noise marker, band power marker, channel power a nd ACP all compute their results using the power band- width of the RBW used for the measurement. Power bandwidth accuracy is the power uncertainty in the results of these measurements due only to bandwidth-related errors. (The analyzer knows this power bandwidth for
each RBW with greater accuracy than the RBW width itself, and can therefore achieve lower errors.) The war-
ranted specifications shown apply to the Gaussian RBW filters used in swept and zero span analysis. There are
four different kinds of filters used in the spectrum analyzer: Swept Gaussian, Swept Flattop, FFT Gaussian and

The only difference between signals within the range ending at –50 dBm and those signals below that level is

note a. There are 44 quasi-random combinations used, tested at a
50 MHz signal frequency. We compute the
95th percentile proportion with 95% confidence for this set observed over a statistically significant number of
instruments. Also, the frequency response relative to the
50 MHz response is characterized by varying the signal
across a large number of quasi-random verification frequencies that are chosen to not correspond with the fre-
quency response adjustment frequencies. We again compute the
95th percentile proportion with 95% confi-
dence for this set observed over a statistically significant number of instruments. We also compute the
95th
percentile accuracy of tracing the calibration of the
50 MHz absolute amplitude accuracy to a national stan-
dards organization. We also compute the 95th percentile accuracy of tracing the calibration of the relative fre-
quency response to a national standards organization. We take the root-sum-square of these four independent
Gaussian parameters. To that rss we add the environmental effects of temperature variations across the
20 to
30°C range. These computations and measurements are made with the mechanical attenuator only in circuit,
set to the reference state of 10 dB.
A similar process is used for computing the result when using the electronic attenuator under a wide range of
settings: all even settings from 4 through
24 dB inclusive, with the mechanical attenuator set to 10 dB. Then the

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 conserva-

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
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.

must be in order to cause a

With Option FS1 or FS2, this table applies for sweep rates that are manually chosen to be the same as or
computes to 100 kHz. This would result in an IF Prefilter Bandwidth from the third row, nominally 303 kHz.
Dynamic Range c. Reference level and off-screen performance: The referenc e level (RL) behavior differs from some earlier analyz- ers in a way that makes this analyzer more flexible. In other analyzers, the RL controlled how the measurement was performed as well as how it was displayed. Because the logarithmic amplifier in these analyzers had both
range and resolution limitations, this behavior was necessary for optimum measurement accuracy. The logarith-
mic amplifier in this signal analyzer, however, is implemented digitally such that the range and resolution greatly
exceed other instrument limitations. Because of this, the analyzer can make measurements largely independent
of the setting of the RL without compromising accuracy. Because the RL becomes a display function, not a mea-
surement 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 fidel-
ity) and small signal effects (noise), the measurement results can change with RL changes when the input atten-
uation is set to auto. d. Mixer power level (dBm) = input power (dBm) − input attenuation (dB). e. The ADC clipping level declines at low frequencies (bel ow 50 MHz) when the LO feedthrough (the signal that appears at 0 Hz) is within 5 times the prefilter bandwidth (see table) and must be handled by the ADC. For
example, with a
300 kHz RBW and prefilter bandwidth at 966 kHz, the clipping level reduces for signal frequen-
cies 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 fre-

RBW-squared, the table applies. Otherwise, compute an "effective RBW" = Span / (SweepTime × RBW). To
determine the IF Prefilter Bandwidth, look up this effective RBW in the table instead of the actual RBW. For
example, for RBW = 3 kHz, Span = 300 kHz, and Sweep time = 42 ms, we compute that Sweep Rate =
7.1
MHz/s, while RBW-squared is 9 MHz/s. So the Sweep Rate is

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

f. Most versions of adjacent channel power measurements us e 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 consis-
tent with other kinds of ACP measurements, this measurement and its specifications will use negative dBc
results, and refer to them as ACPR, instead of positive dB results referred to as ACLR. The ACLR can be deter-

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
For example, if the average input power is

the normal

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

analysis equipment, but this incoherent addition model is rarely justified. This derived accuracy specification is

Power Suite Measurements l. Keysight measures 100 % of the signal analyzers for dynamic range in the factory production process. This mea- surement 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

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 dif-

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

the RBW used in the measurement interact. The analyzer compensates the shape of the RRC filter to accommo-

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

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 test-
ing with the IBW method. It is 0.000 dB for the
27 kHz RBW filter used for BTS testing. The worst error for

a. The IF frequency response includes effects due to RF circui ts such as input filters, that are a function of RF fre-

d. The maximum error at an offset (f) from the center of the FFT width is given by the expression ± [Midwidth Error +

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

a. This table is meant to help predict the full-scale level, defined as the signal level for which ADC overload (clip-
ping) occurs. The prediction is imperfect, but can serve as a starting point for finding that level experimentally.
A SCPI command is also available for that purpose. b. Mixer level is signal level minus input attenuation. c. The available gain to reach the predicted mixer level will vary with center frequency. Combinations of high gains and high frequencies will not achieve the gain required, increasing the full scale level.

条件:Spurious Responses There are three effects of the use of Option B40 on spurious responses.
Most of the warranted elements of the “Spurious Responses” on
page 43 still apply without changes, but the revised-version of the table
on page 43, 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
Phase Noise 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
Absolute Amplitude Accuracy Nominally

Specifications on this bandwidth only apply with center frequencies of
30 MHz and higher.
