and interactive EMI measurements
The ¸ESIB family of EMI test receivers combines the high sensitivity, large
dynamic range and selectivity of a highend test receiver with the fl exibility and
speed of a top-class spectrum analyzer
in one instrument.
The ¸ESIB family comprises three
models with different upper frequency
limits:
¸ESIB 7 (20 Hz to 7 GHz)
◆
¸ESIB 26 (20 Hz to 26.5 GHz)
◆
¸ESIB 40 (20 Hz to 40 GHz)
◆
The upper frequency limit of the
¸ESIB 26 and ¸ESIB 40 can be
extended up to 110 GHz by means of
external mixers (option ¸FSE-B21
required).
All three models have the following
characteristics:
High sensitivity
◆
Excellent large-signal immunity
◆
Low measurement uncertainty
◆
High measurement speed

measurements
The ¸ESIB carries out measurements
in conformance with all commercial and
military EMI standards such as CISPR,
EN, VDE, ANSI, FCC, BS, ETS, VCCI,
MIL-STD, VG, DEF-STAN, DO 160 and
GAM EG 13. It goes without saying that
the ¸ESIB family complies with
the basic standard, i.e. CISPR 16-1-1 or
VDE 0876, which places stringent
requirements on receiver dynamic range.
Test routines oriented to
practical requirements
During the various development phases
of a product, different measurements are
performed as required for each stage.
The ¸ESIB family offers appropriate
features and routines for the different
development stages.
Early in development, functional measurements play the predominant role.
While EMI measurements are important right from the beginning to avoid
re designs, the ¸ESIB at this stage
primarily functions as a high-grade
spectrum analyzer.
The ¸ESIB is outstanding for its low
inherent noise, high intermodulation
suppression and low SSB phase noise.
Moreover, the ¸ESIB provides all
test routines offered by modern spectrum analyzers, such as noise measurement, phase noise measurement,
channel and adjacent-channel power
measurement as well as time-domain
measurement.
As development progresses, EMI measurements become more and more
important, for example on modules and
their interfaces. Measurements are
frequently carried out using sensors,
probes or current transformers. Interference analysis and referencing of results
to limit values are important. Here, too,
the ¸ESIB family meets all relevant
requirements in terms of performance,
functionality and economy of operation:
Fast overview measurements with

mode) or in test receiver mode (scan
mode) with tuning in user-defi ned

and 10 MHz, selectable in steps of 1,

for RFI fi eld-strength measurements by
means of test antennas, or for RFI power
measurements with absorbing clamps.
Especially measurements using artifi cial
mains networks and absorbing clamps
put the pulse-handling capability of the
RF input to a severe test. The ¸ESIB
solves this problem by means of a
second, pulse-protected input for the
frequency range from 20 Hz to 1 GHz. In
the case of the ¸ESIB 7, for example, this input can handle pulses with
voltages up to 1500 V and powers up
to 30 mWs without any damage being
caused. Pulses generated by artifi cial
mains networks during phase switching
or during RFI power measurements on
ignition cables using absorbing clamps
pose no problem.
The input bandwidth of the frontend is
limited by preselection fi lters to reduce
the total voltage level at the input mixer
to an extent compatible with the wide
dynamic range required for quasi-peak
detection in the CISPR frequency range.

Example of transducer set: combination of antenna + cable
Up to 2 MHz, the ¸ESIB family
uses fi xed-tuned fi lters; from 2 MHz to
1000 MHz, the preselection fi lters operate as tracking fi lters.
An autorange function is available for
the automatic setting of attenuation and
gain in the RF and IF signal paths. This
function ensures the correct combination of attenuation and gain depending
on the test level or any overload of a signal stage caused by pulses or sinusoidal signals. So the operator is not burdened with the internal workings of the
test receiver.
4 EMI Test Receivers ¸ESIB
To measure extremely small voltage
levels occurring, for example, in EMI
measurements on vehicle antennas in
line with CISPR 25, the ¸ESIB family
offers a 20 dB preamplifi er from 9 kHz to
7 GHz (above 7 GHz as option
¸ESIB-B2). The preamplifi er is located between the RF preselection and the
input mixer to be protected against overload. With this preamplifi er, the inherent noise of the ¸ESIB is lowered to
such an extent that the RFI fi eld strength
obtained in an overview measurement
using the peak detector, a log- periodic
antenna (e.g. ¸HL 223) and a 10 m
connecting cable clearly remains below
the EN 55022 quasi-peak limit (Fig. 1).
Fig. 2 shows the SCAN table stipulated
for commercial EMI measurements as a
function of the prescribed CISPR bandwidths.
To achieve high sensitivity in measurements in line with MIL-STD-461D RE 101
in the frequency range from 30 Hz, the
unavoidable feedthrough of the 1st LO
at the input mixer is suppressed by self-

alignment of the mixer. The ¸ESIB
consequently features suffi cient inherent
noise suppression with respect to relevant limit values even at the lower frequency limit (Fig. 3).
Defi nition of
standard test sequences
To meet the requirements of relevant
standards, measurements over various
frequency ranges and bandwidths have
to be performed, using different step
sizes and measurement times or differ-
ent receiver settings regarding RF attenuation and preamplifi cation. It must also
be possible to confi gure a scan matched
to DUT characteristics. For this purpose,
the ¸ESIB offers a user-confi gurable
scan table with up to ten subranges.
Calibration values for transducer factors
of absorbing clamps or antennas, for
example, are stored in tables and can be
switched on as required. The transducer
factors can also be combined into transducer sets, for example to display the
i nterference spectrum in the correct unit
dBμV/m in measurements with an
antenna and a connecting cable
(Figs. 4 to 7).

EMI emissions are usually measured in
two steps. An overview measurement
performed with the peak detector identifi es critical emissions above or close
to limit values (Fig. 8). In a second measurement with the prescribed CISPR
detectors and an appropriate measurement time, the critical frequencies are
checked for compliance with limit values. The ¸ESIB family supports this
procedure by two independent measurement windows on the screen and offers
automatic or interactive evaluation functions for preview measurements, generation of a peak list (data reduction) and
fi nal measurement.

Split-screen display
Critical emissions can be measured with
numeric display of frequency and level
as with classic receivers. Bargraphs
provide an analog display of measured
values for the various detectors simultaneously and in different colors (Fig. 9).
By coupling the marker in the overview
spectrum to the receiver frequency,
emissions can be measured fast and reliably in line with standards.
In the second window, the operator can
zoom in on the displayed trace (Fig. 10).
6 EMI Test Receivers ¸ESIB
Zooming is effected either based on
stored measured data or by means of a
new measurement with the selected detectors. If stored data is used, all stored
values can be displayed. For this, the
¸ESIB can store up to 250 000 measured values with one trace active in
background operation. This considerably
reduces measurement time, since no
new measurement is needed to make a
detailed analysis.
Listen, view, measure
To analyze the spectrum and to exclude
ambient noise, such as originating from
sound or TV broadcast transmitters or
the like, it is expedient to select single
frequencies by means of the markers,
tune the receiver frequency to the marker frequency, and activate the audio
path with the built-in AM/FM demodulator by switching on the loudspeaker or headphones. Acoustic identifi cation is very frequently and successfully
used in EMI signal analysis, all the more
so since manual pre-/postmeasurements
and interactive operation support this
approach.

word processing programs for the generation of test reports.
Selftest
High accuracy
In the frequency range up to 1 GHz, the
¸ESIB performs level measurements
with an accuracy of ±1 dB. This is clearly better than the value of ±2 dB specifi ed by CISPR 16-1-1, and is achieved by
individual correction factors stored on all
modules affecting measurement uncertainty. The operator can run calibration
routines for the frequency response,
display linearity and signal path gain
correction for the various instrument settings, thus ensuring low measurement
uncertainty under all specifi ed environmental conditions.
The built-in selftest supports fault local-
ization down to module level. With in-
dividual correction tables being stored
on each module, defective modules can
be replaced largely without any adjust-
ment or additional instruments. Down-
times and repair costs are reduced to a
minimum.

functionality without requiring additional
