Vector Signal Analysis Software for DPO7000 and DPO/DSA70000 Series
Oscilloscopes
Wideband Signal Characterization
SignalVu
vector signal analysis software helps you easily validate wideband
designs and characterize wideband spectral events. By combining the
signal analysis engine of the RSA6000 Series real-time spectrum analyzer
with that of the industry’s widest bandwidth digital oscilloscopes,
designers can now evaluate complex signals up to 20 GHz without the
need of an external down converter. You get the functionality of a
vector signal analyzer, a spectrum analyzer, and the powerful trigger
capabilities of a digital oscilloscope — all in a single package.
Whether your design validation needs include wideband radar, high
data rate satellite links, or frequency hopping communications, SignalVu
vector signal analysis software can speed your time-to-insight by
showing you time-variant behavior of these wideband signals.
SignalVu is an integrated software application for DPO7000 and DPO/DSA70000
Series digital oscilloscopes. Users can easily switch between the
SignalVu application and the oscilloscope’s user interface to optimize
the collection of wideband acquisitions.
Trigger
SignalVu software works seamlessly with the oscilloscope allowing
users to utilize all of its powerful triggering capabilities. The
ability to trigger on time- and amplitude-varying events of interest
is paramount in wideband system design, debug, and validation. The
DPO7000 and DPO/DSA70000 Series’ Pinpoint trigger system allows selection
of virtually all trigger types on both A and B trigger events whether
they be transition, state, time, or logic qualified triggers. Once
triggered, SignalVu processes the acquisition for analysis in multiple
domains.
Powerful oscilloscope triggers allow the user
to capture only the relevant portion of wideband signals. Pinpoint
trigger functions such as combining A and B events with Edge with
Holdoff can capture a pulse train during a specific transmitter mode
of operation.
Capture
Capture
once – make multiple measurements without recapturing. All signals
in an acquisition bandwidth are recorded into the oscilloscope’s deep
memory. Up to four channels can be captured simultaneously; each of
which can be independently analyzed by SignalVu software. Users can
also apply math functions to the acquisition prior to SignalVu’s analysis.
Acquisition lengths vary depending upon the selected capture bandwidth
– up to 12.5 ms can be acquired on a single channel with the DPO7000
Series and up to 5 ms can be captured on a single channel with the
DPO/DSA70000 Series. Significantly longer capture times can be realized
with lower oscilloscope sample rates.
Once captured
into memory, SignalVu provides detailed analysis in multiple domains.
The spectrogram display (left panel) shows the frequency of an 800 MHz
wide LFM pulse changing over time. By selecting the point in time
in the spectrogram during the On time of the pulse, the chirp behavior
can be seen as it sweeps from low to high (lower right panel).
Analyze
SignalVu vector signal analysis
software utilizes the same analysis capabilities found in the RSA6000
Series real-time spectrum analyzers. SignalVu advances productivity
for engineers working on components or in wideband RF system design,
integration, and performance verification, or operations engineers
working in networks, or spectrum management. In addition to spectrum
analysis, spectrograms display both frequency and amplitude changes
over time. Time-correlated measurements can be made across the frequency,
phase, amplitude, and modulation domains. This is ideal for signal
analysis that includes frequency hopping, pulse characteristics, modulation
switching, settling time, bandwidth changes, and intermittent signals.
SignalVu can process acquisitions from any one of the four available
oscilloscope inputs. Math functions applied by the oscilloscope are
also utilized by SignalVu allowing users to apply custom filtering
prior to vector signal analysis.
Options Tailored for Your
Wideband Applications
SignalVu vector signal analysis
software is available for all DPO7000 and DPO/DSA70000 Series oscilloscopes
and offers options to meet your specific application, whether it be
wideband radar characterization, broadband satellite, or spectrum
management. SignalVu Essentials (Opt. SVE) provides the fundamental
capability for all measurements and is required for both pulse analysis
(Opt. SVP) and digital modulation analysis (Opt. SVM).

The Windows XP environment makes this multidomain
analysis even easier with an unlimited number of analysis windows,
all time-correlated, to provide deeper insight into signal behavior.
A user interface that adapts to your preferences (keyboard, front
panel, touchscreen, and mouse) makes learning SignalVu easy for both
first-time users and experienced hands.
Time-correlated,
multidomain view provides a new level of insight into design or operational
problems not possible with conventional analysis solutions. Here,
the hop patterns of a narrowband signal can be observed using Spectrogram
(lower left) and its hop characteristics can be precisely measured
with Frequency vs, Time display (upper left). The time and frequency
responses can be observed in the two right-hand views as the signal
hops from one frequency to the next.
The Advanced Signal Analysis package (Opt. SVP) provides
21 individual measurements to automatically characterize long pulse
trains. An 800 MHz wide LFM chirp centered at 18 GHz is seen here
with measurements for pulses 7 through 18 (upper right). The shape
of the pulse can be seen in the Amplitude vs. Time plot shown in the
upper left. Detailed views of pulse #8’s frequency deviation and parabolic
phase trajectory are shown in the lower two views.
Wideband satellite and point-to-point microwave links
can be directly observed with SignalVu analysis software and appropriate
DPO oscilloscope. Here, General Purpose Digital Modulation Analysis
(Opt. SVM) is demodulating a 16QAM backhaul link running at 312.5 MS/s.
