EMI Precompliance Measurements
Over the past two decades,
precompliance emissions
measurements have been gaining in
popularity. Performing precompliance
radiated and conducted emissions
measurements early in the design
cycle can reduce development
expense and speed time to market by
ensuring new designs will pass inal
compliance testing at an accredited
facility the irst time around, without
costly redesign and re-testing.
For a step-by-step guide on how to
make precompliance measurements
according to regulatory agency limits,
refer to the application note, Making
Conducted and Radiated Emissions
Measurements, literature number
5990-6152EN.
Conducted emissions
measurements
The EMI measurement application
allows you to measure the emissions
that are conducted along a power
line. The transducer used to couple
the emissions of the power line to the
signal analyzer is a line impedance
stabilization network (LISN). The
frequency range of conducted
emissions is 9 kHz to 30 MHz
depending on the regulatory agency.
Radiated emissions
measurements
Performing precompliance radiated
emissions measurements is not
as straight forward as conducted
emissions measurements. When
measuring to commercial standards,
the antenna is placed 3 to 10 meters
from the device under test (DUT) and
the DUT should be rotated in order
to ind the maximum radiation. With
the addition of the EMI measurement
application, the X-Series signal
analyzer becomes a powerful
EMI precompliance measurement
analyzer. Measure designs to the
latest CISPR 16-1-1 or MIL-STD
requirements. The robust signal
list feature enables you to quickly
differentiate between the DUT and
the ambient signal environment.
Regulatory standards
X-Series signal analyzers with the
EMI measurement application can
be used for making precompliance
measurements to any international
EMC standard. Simply select the
performance level and frequency
range for your application.
