SignalVu™ Vector Signal Analysis Software for MSO/DPO5000, DPO7000, and DPO/DSA/MSO70000 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 RSA5000 and RSA6000 Series real-time spectrum analyzer with that of the industry’s widest bandwidth digital oscilloscopes, designers can now evaluate complex signals 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 MSO/DPO5000, DPO7000, and DPO/DSA/MSO70000 Series digital oscilloscopes. Users can easily switch between the SignalVu application and the oscilloscope’s user interface to optimize the collection of wideband signals.

Trigger

Thumbnail

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.

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 Tektronix oscilloscopes' trigger systems allow 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.

Capture

Thumbnail

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).

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. Channels can be RF, I and Q, or differential inputs. Users can also apply math functions to the acquisition prior to analysis by SignalVu. Acquisition lengths vary depending upon the selected capture bandwidth – up to 25 ms can be captured on a single channel with the MSO/DPO5000 Series, up to 12.5 ms can be acquired on a single channel with the DPO7000 Series, and up to 2.5 ms can be captured on a single channel with the DPO/DSA/MSO70000 Series. Significantly longer capture times can be realized with lower oscilloscope sample rates.

Using the FastFrame segmented memory feature in SignalVu enables you to capture events of interest, such as low duty cycle pulsed signals, while conserving acquisition memory. Using multiple trigger events, FastFrame captures and stores short-duration, bursty signals and passes them to SignalVu vector signal analysis functions. Capturing thousands of frames is possible, so long-term trends and changes in the bursty signal can be analyzed.

Analyze

SignalVu vector signal analysis software utilizes the same analysis capabilities found in the RSA5000 and 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 RF, I and Q, and differential I and Q signals 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 MSO/DPO5000, DPO7000, and DPO/DSA/MSO70000 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 pulse analysis (Opt. SVP), settling time (Opt. SVT), digital modulation analysis (Opt. SVM), flexible OFDM analysis (Opt. SVO), and AM/FM/PM Modulation and Audio Measurements (Opt. SVA).

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 27 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.
