Agilent.89600.Vector.Signal.Analyzer.v18

The Agilent Technologies 89600
Series vector signal analyzer (VSA)
facilitates faster and easier
communication system design from
initial design simulation to final
hardware prototype. It offers 36 MHz
bandwidth capacity for measuring
signals such as cellular and satellite
communications, digital video, wireless
LAN (WLAN), and local multipoint
distribution service (LMDS).
Spectrum analyzers with
demodulation capability are
useful tools for highlighting an
existing problem. However, many
DSP or RF problems can create high
adjacent channel power or p
oorly
locked constellations. With the
89600 VSA’s sophisticated and
unique error analysis tools, you
can actually determine the root
causes of the problems.
The 89600 Series VSA dynamically
links to Agilent’s Advanced Design
System (ADS), electronic design
automation software. This tight
linkage means you can use the 89600
to evaluate simulated data and
measurement results from hardware
— providing you confidence in results
because the same measurement
algorithms are used during simulation
and test.
Links to the Agilent ESG signal
generators from both the ADS
software and the 89600 VSA mean
you no longer need to wait for all of
the hardware stages in a block diagram
to come back from fabrication to
look for system level problems.
In combination with the ESG, the
89600 VSA can uncover RF and
DSP problems throughout the
radio block diagram — even before
hardware exists.
Working with hard-to-measure
signals — bursted, hopped,
modulated — is a fact of life for
designers of today’s high-performance
communications systems. When
creating a new design, it takes
time to find the causes of system
problems. The Agilent 89600 Series
VSAs combine time-, frequency-
and modulation-domain analysis to
provide measurements and displays
that help you look in the right
place sooner.
More than a spectrum analyzer
The 89600 VSAs provide traditional
spectrum displays and measurements,
but today a spectrum analyzer isn’t
enough. New digital formats require
new measurements. Familiar tools
such as spectrum analyzers with
demodulation may indicate that a
problem exists, but they can’t help
you understand the cause of the
problem. For instance, incorrect
filtering, spurious interference,
incorrect interpolation, DAC overflow,
symbol mistiming and other errors
may all increase adjacent channel
power and distort the constellation.
The 89600 Series VSA can identify
which of these is the root cause of
the problem.
Troubleshoot RF and
DSP Problems
These two signals appear almost
identical when viewed with a spectrum
analyzer. However, this radio will not
transmit a bit. The second signal is off in
its center frequency, symbol clock rate,
and filter alpha. Spectrum analyzers with
demodulation will all show high ACPR
and a cloudy constellation, but only a
89600 VSA can identify these problems
with a single screen using its EVM
versus time display
