W6141A Datasheet, PDF (2/11 Pages) Keysight Technologies – X-Series Measurement Application

EMI Measurement Application
To avoid costly delays that can result
from failed compliance testing,
Keysight's EMI measurement
application on X-Series signal
analyzers allows you to perform
precompliance measurements and
diagnostic evaluation of your designs.
Find and ix problems before they
enter the test chamber with the
N6141A measurement application
on the N9030A PXA, N9020A MXA,
or N9010A EXA, or W6141A on the
N9000A CXA for a low-cost pre-
compliance test solution.
The application’s wide range of
features enables you to:
– Use the scan table to set
up frequency ranges, gains,
bandwidths, and dwell time
– Scan a frequency range and
display the results in log or linear
format
– Identify suspect signals in the
frequency scan
– Measure the peak, quasi-peak,
EMI-average or RMS-average
values of these suspect signals
and place the results in the
signal list
– Easily identify signals that fail the
regulatory agency limit
The EMI measurement application
is just one in a common library
of more than 25 measurement
applications in the Keysight X-Series,
an evolutionary approach to signal
analysis that spans instrumentation,
measurements and software. The
X-Series analyzers, with upgradeable
CPU, memory, disk drives, and I/O
ports, enable you to keep your test
assets current and extend instrument
longevity. Proven algorithms, 100%
code-compatibility and a common
UI across the X-Series create a
consistent measurement framework
for signal analysis that ensures
repeatable results and measurement
integrity so you can leverage your
test system software through all
phases of product development. You
can further extend your test assets
by transporting applications across
multiple X-Series signal analyzers.
Key features
– Measure emissions with
built-in commercial–and MIL-
STD–compliant bandwidths,
detectors, and band presets
– Compare measured emissions to
regulatory limits
– Continuously monitor signals
with bar meters to detect
maximum amplitude
– Collect lists of suspect emissions
– Differentiate between ambient
signals and device emissions
– View signals over time to identify
intermittent responses
– Generate reports in HTML format
including signal list, images and
trace, and correction data
EMI measurement
application vs. Option EMI
There are two EMI options
for X-Series signal analyzers:
Option EMC and the N/W6141A
measurement application.
Option EMC enables basic EMC
measurements. It contains CISPR
16-1-1 compliant bandwidths and
detectors (peak, quasi-peak, EMI
average, RMS average) as well
as CISPR band presets (bands A
through E), and MIL-STD bandwidths
that meet MIL-STD 461D/E/F
requirements.
The EMI measurement application
includes Option EMC and provides
a wide range of additional features
that enable the user to perform
precompliance conducted and
radiated emissions tests to
both commercial and MIL-STD
requirements. The following table
summarizes a comparison of features.
