EXA Signal Analyzer
Definitions and Requirements
Definitions and Requirements
This book contains signal analyzer specifications and supplemental
information. The distinction among specifications, typical performance, and
nominal values are described as follows.
Definitions
— Specifications describe the performance of parameters covered by the
product warranty (temperature = 5 to 55°C also referred to as "Full
temperature range" or "Full range", unless otherwise noted).
— 95th percentile values indicate the breadth of the population (≈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.
Conditions Required to Meet Specifications
The following conditions must be met for the analyzer to meet its
specifications.
— The analyzer is within its calibration cycle. See the General section of this
chapter.
— Under auto couple control, except that Auto Sweep Time Rules = Accy.
— For signal frequencies < 10 MHz, DC coupling applied.
— 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
14
EXA Signal Analyzer
Definitions and Requirements
choices, the analyzer may fail to meet specifications without informing the
user. If Auto Align is set to Light, performance is not warranted, and
nominal performance will degrade to become a factor of 1.4 wider for any
specification subject to alignment, such as amplitude tolerances.
Certification
Keysight Technologies certifies that this product met its published
specifications at the time of shipment from the factory. Keysight Technologies
further certifies that its calibration measurements are traceable to the
International System of Units (SI) via national metrology institutes
(www.keysight.com/find/NMI) that are signatories to the CIPM Mutual
Recognition Arrangement.

a. AC Coupled only applicable to Freq Options 503, 507, 513, and 526.
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 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 7.0 GHz” represent nominal performance from 3.5 to 3.6 GHz, and warranted performance from 3.6 to 7.0 GHz

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. Narrow temperature range performance is nominally linear with temperature. For example, for
25±3º C, the stability would be only three-fifths as large as the warranted 25±5º C, thus ±0.9 × 10
−8
.
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.
19

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
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 0.25% × 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 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. Instrument conditions: RBW = 1 kHz, gate time = auto (100 ms), S/N ≥ 50 dB, frequency = 1 GHz
b. If the signal being measured is locked to the same frequency reference as the analyzer, the specified count
accuracy is ±0.100 Hz under the test conditions of footnote a. This error is a noisiness of the result. It will
increase with noisy sources, wider RBWs, lower S/N ratios, and source frequencies > 1 GHz.

a. The noise marker, band power marker, channel power and ACP all compute their results using the power 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 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.
