Overcome your test challenges
with the 81180A arbitrary waveform
generator
Electronic devices continue to grow increasingly complex,
and the demand for higher performance never ends. In
addition, you are under pressure to reduce test times and
tighten specifications.
The complexity of modern wireless systems skyrockets
when you use techniques like digital modulation that
compress wireless data to use bandwidth more efficiently.
Test accuracy and repeatability are critical. In radar
applications, a higher range helps you detect targets
further out, and increased accuracy helps you better track
targets. Range is proportional to the length of a pulse, so
parameters like pulse length and pulse repetition frequency
influence the radar range and range resolution. You need
to be able to verify the performance of your radar system.
Commercial off-the-shelf waveform packages are seldom
available for devices under test used in aerospace and
defense applications, so testing system performance is
challenging. To test your DUTs to their limits, you need
flexible stimulus generating capability for any signal you
can imagine.

New high-bandwidth, high-resolution
arbitrary waveform generator helps
you test with confidence
The Agilent 81180A arbitrary waveform generator provides
4.2 GSa/s, 2 GHz IQ modulation bandwidth and 12-bit
vertical resolution for applications where waveform
resolution is an issue.
Data-centric warfare requires real-time data and video
communication. Satellite designers are pushed to use
bandwidth greater than 1 GHz bandwidth.
In addition, these bandwidths need to be available at
higher carrier frequencies up to 44 GHz. New emerging
standards like wireless HD or WiGig call for up conversion
up to 60 GHz.
These setups require a reliable and precise modulation
source. Any signal distortion gets multiplied by each of
the test instruments, making it difficult to pinpoint a DUT
failure. When the foundation for your signals is more
precise, your test results are more meaningful. You want to
test your DUT, not the source.
To meet these challenges,
you need new test tools.
