2 EMI Test Receivers ¸ESIB
The ¸ESIB family of EMI test receiv-
ers combines the high sensitivity, large
dynamic range and selectivity of a high-
end 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

Standard-conforming
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 mea-
surements play the predominant role.
While EMI measurements are impor-
tant 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 spec-
trum analyzers, such as noise mea-
surement, phase noise measurement,
channel and adjacent-channel power
measurement as well as time-domain
measurement.
As development progresses, EMI mea-
surements become more and more
important, for example on modules and
their interfaces. Measurements are
frequently carried out using sensors,
probes or current transformers. Interfer-
ence 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
linear or logarithmic frequency scale
in spectrum analyzer mode (sweep
mode) or in test receiver mode (scan
mode) with tuning in user-defi ned
frequency steps with selectable
measuring times per step
Bandwidths conforming to
CISPR 16-1-1 (200 Hz, 9 kHz, 120 kHz
and 1 MHz) and MIL-STD (10 Hz to
1 MHz), plus 10 MHz bandwidth, and
analyzer bandwidths between 1 Hz
and 10 MHz, selectable in steps of 1,
2, 3 and 5 ◆
