1 Agilent MXE EMI Receiver
This chapter contains the specifications for the EMI receiver. The specifications and characteristics for
the measurement applications and options are covered in the chapters that follow.

10 Chapter1
Agilent MXE EMI Receiver
Definitions and Requirements
Definitions and Requirements
This book contains EMC receiver specifications and supplemental information. The distinction among
specifications, typical performance, and nominal values are described as follows.
Definitions
• Specifications describe the performance of parameters covered by the product warranty (temperature
= 5° to 50°C, unless otherwise noted).
• 95th percentile values indicate the breadth of the population (≈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 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.
Certification
Agilent Technologies certifies that this product met its published specifications at the time of shipment
from the factory. Agilent Technologies further certifies that its calibration measurements are traceable to
the United States National Institute of Standards and Technology, to the extent allowed by the Institute’s
calibration facility, and to the calibration facilities of other International Standards Organization
members.

Frequency and Time
c. In the band overlap regions, for example, 3.5 to 3.6 GHz, the receiver may use either band for measure-
ments, 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 specifica-
tions 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 war-
ranted. The specifications for the alternate band are not warranted in the band overlap region, but per-
formance 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 specifica-
tion 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 situa-
tion 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. The specification applies after the receiver has been powered on for four hours.
c. 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 Calibra-
tion 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 environment
3) Retrace effects in both the calibration environment and the use environment due to turning the
instrument power off.
4) Settability
e. N is the LO multiplication factor.

Example for EMCd±0.0032%(nominal)
a. The warranted performance is only the sum of all errors under autocoupled conditions. Under
non-autocoupled conditions, the frequency readout accuracy will nominally meet the specification
equation, except for conditions in which the RBW term dominates, as explained in examples below.
The nominal RBW contribution to frequency readout accuracy is 2%of RBW for RBWs from 1 Hz to
390 kHz, 4%of RBW from 430 kHz through 3 MHz (the widest autocoupled RBW), and 30%of RBW
for the (manually selected) 4, 5, 6 and 8 MHz RBWs.
First example: a 120 MHz span, with autocoupled RBW. The autocoupled ratio of span to RBW is
106:1, so the RBW selected is 1.1 MHz. The 5%×RBW term contributes only 55 kHz to the total fre-
quency readout accuracy, compared to 300 kHz for the 0.0.25%×span term, for a total of 355 kHz. In
this example, if an instrument had an unusually high RBW centering error of 7%of RBW (77 kHz) and
a span error of 0.20%of span (240 kHz), the total actual error (317 kHz) would still meet the computed
specification (355 kHz).
Second example: a 20 MHz span, with a 4 MHz RBW. The specification equation does not apply
because the Span: RBW ratio is not autocoupled. If the equation did apply, it would allow 50 kHz of
error (0.25%) due to the span and 200 kHz error (5%) due to the RBW. For this non-autocoupled RBW,
the RBW error is nominally 30%, or 1200 kHz.
b. Horizontal resolution is due to the marker reading out one of the sweep points. The points are spaced
by span/(Npts –1), where Npts is the number of sweep points. For example, with the factory preset
value of 1001 sweep points, the horizontal resolution is span/1000. However, there is an exception:
When both the detector mode is “normal” and the span > 0.25 ×(Npts –1) ×RBW, peaks can occur
only in even-numbered points, so the effective horizontal resolution becomes doubled, or span/500 for
the factory preset case. When the RBW is autocoupled and there are 1001 sweep points, that exception
occurs only for spans > 750 MHz.
c. Specifications apply to traces in most cases, but there are exceptions. Specifications always apply to the
peak detector. Specifications apply when only one detector is in use and all active traces are set to Clear
Write. Specifications also apply when only one detector is in use in all active traces and the "Restart"
key has been pressed since any change from the use of multiple detectors to a single detector. In other
cases, such as when multiple simultaneous detectors are in use, additional errors of 0.5, 1.0 or 1.5
sweep points will occur in some detectors, depending on the combination of detectors in use.
d. In most cases, the frequency readout accuracy of the receiver can be exceptionally good. As an exam-
ple, Agilent has characterized the accuracy of a span commonly used for Electro-Magnetic Compatibil-
ity (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 highest allowed mixer level depends on the IF Gain. It is nominally –10 dBm for Preamp Off and
IF Gain = Low.
b. Noise will limit trigger level range at high frequencies, such as above 15 GHz.

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 Accu-
racy instead of Normal. The true bandwidth, which determines the response to impulsive signals and
noise-like signals, is not affected by the sweep rate.
