UXA Signal Analyzer Definitions and Requirements
Definitions and Requirements
This book contains signal analyzer specifications and supplemental information. The distinction among specifications, typical performance, and nominal values are described as follows.
Definitions
— Specifications describe the performance of parameters covered by the product warranty (and
apply to room temperature range 20 to 30°C unless otherwise noted). Some specification parameters may be labeled as "Full Temperature Range" or "Full Range" and are warranted over a temperature range of 0 to 40°C.
— 95th percentile values indicate the breadth of the population (≈2σ) 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.
— The term "attenuation" is used for many specifications in this document. Statements about
Attenuation setting refer to the Mechanical Attenuator, unless otherwise stated.
Conditions Required to Meet Specifications
The following conditions must be met for the analyzer to meet its specifications.
— The analyzer is within its calibration cycle. See the General section of this chapter. — Under auto couple control, except that Auto Sweep Time Rules = Accy. — Any analyzer that has been stored at a temperature range inside the allowed storage range but
outside the allowed operating range must be stored at an ambient temperature within the allowed operating range for at least two hours before being turned on.
— The analyzer has been turned on at least 30 minutes with Auto Align set to Normal, or if Auto
Align is set to Off or Partial, alignments must have been run recently enough to prevent an Alert message. If the Alert condition is changed from “Time and Temperature” to one of the disabled duration choices, the analyzer may fail to meet specifications without informing the user. 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.

a. In the band overlap regions, for example, 3.5 to 3.6 GHz, the analyzer may use either band for measurements, in
this example Band 0 or Band 1. The analyzer gives preference to the band with the better overall specifications (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 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.
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.

a. 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.” b. The specification applies after the analyzer has been powered on for four hours. c. Standby mode applies power to the oscillator. Therefore warm-up and retrace only apply if the power connec-
tion is lost and restored. The warm-up reference is one hour after turning the power on. The effect of retracing
is included within the “Achievable Initial Calibration Accuracy” term of the Accuracy equation. d. The achievable calibration accuracy at the beginning of the calibration cycle includes these effects:
1) Temperature difference between the calibration environment and the use environment
2) Orientation relative to the gravitation field changing between the calibration environment and the use 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 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 0.10% × 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 trace points. The points are spaced by
span/(Npts – 1), where Npts is the number of sweep points. For example, with the factory preset value of 1001 sweep points, the horizontal resolution is span/1000. However, there is an exception: When both the detector mode is “normal” and the span > 0.25 × (Npts – 1) × RBW, peaks can occur only in even-numbered points, so the effective horizontal resolution becomes doubled, or span/500 for the factory preset case. When the RBW is autocoupled and there are 1001 sweep points, that exception occurs only for spans >750 MHz
c. 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 analyzer 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
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 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 war­ranted specifications shown apply to the Gaussian RBW filters used in swept and zero span analysis. There are four different kinds of filters used in the spectrum analyzer: Swept Gaussian, Swept Flattop, FFT Gaussian and FFT Flattop. While the warranted performance only applies to the swept Gaussian filters, because only they are kept under statistical process control, the other filters nominally have the same performance.

b. The ratio of the noise bandwidth (also known as the power bandwidth) to the RBW has the nominal value and
tolerance shown. The RBW can also be annotated by its noise bandwidth instead of this 3 dB bandwidth. The accuracy of this annotated value is similar to that shown in the power bandwidth accuracy specification.
c. Resolution Bandwidth Accuracy can be observed at slower sweep times than auto-coupled conditions. Normal
sweep rates cause the shape of the RBW filter displayed on the analyzer screen to widen significantly. The true bandwidth, which determines the response to impulsive signals and noise-like signals, is not affected by the sweep rate.
