About Tektronix Analyzers Product Description
Product Description
SignalVu™ vector signal analysis software helps you easily validate wideband designs and characterize
wideband spectral events. By combining the signal analysis engine of the RSA6100B Real-Time Analyzer
with that of t
signals up to 20 GHz without the need of an external down converter. You get the functionality of a vector
signal analyzer, a signal 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.
Key Features
he industry’s widest bandwidth digital oscilloscopes, designers can now evaluate complex
Tightly i
oscilloscope user interfaces to optimize triggers and other acquisition parameters. Key features of
SignalVu include:
ntegrated software and hardware control allows you to easily switch between SignalVu and
Direct observation of microwave signals to 2 0 GHz without an external down converter
All sig
Customizable oscilloscope acquisition parameters for effective use of capture memory
Four channel acquisitions help you correlate independent RF events
Apply custom math and filtering to acquisition channels
Extensive time-correlated, multi-domain displays connect problems in time, frequency, phase and
amplitude for quicker understanding of cause and effect when troubleshooting
Power measurements and signal statistics help you characterize components and systems: ACLR,
Multi-Carrier ACLR, Power vs. Time, CCDF, OBW/EBW, and Spur Search
Advanced Signal Analysis Suite (Opt. SVP) provides automated pulse measurements including rise
time, pulse width and pulse-to-pulse phase provide deep insight into pulse train behavior
General Purpose Digital Modulation Analysis (Opt. SVM) provides vector signal analyzer
functionality
Settling Time Measurements (Option SVT) provides Frequency and Phase settling time measurements

Connecting Signals and Selecting the Analysis Channel
SignalVu analyzes signals acquired by the oscilloscope. The SignalVu software analyzes one, two, or
four signals at a time, so you need to specify which oscilloscope input channels to use. Math and Ref
channels can
To specify which oscilloscope channel is analyzed:
1. Select Settings > Acquire to display the Acquire control panel.
2. Select the desired signal type from the Signal Input drop-down list along the left side of the control
panel. Available choices are RF (uses one oscilloscope channel), IQ (uses two channels), and Diff IQ
(uses four channels).
3. On the Ve rtic al tab, use the Source drop-down list(s) to select the channels to analyze.
4. Use the oscilloscope controls in the TekScope application to achieve a stable, triggered signal.
For information on the oscilloscope input signal capabilities and how to trigger on a signal, see the
oscilloscope's help. Note that SignalVu does not control triggering on the oscilloscope; you will need to
use the oscilloscope triggering functions to achieve a stable, triggered signal on the oscilloscope.

4. Set the modulation parameters for your signal. This includes the Modulation Type, Symbol Rate,
Measurement Filter, Reference Filter and Filter Parameter. All of these settings are accessed by
pressing the Settings button.

3. Set the Reference Level to place the peak of the pulse signal approximately 0-10 dB down from

You may need to trigger on the signal to get a more stable display. This is set up with the oscilloscope's
controls. A rising-edge trigger works well for many pulsed signals.
4. Set the Analysis Period to cover the number of pulses in your signal that you want to analyze. To do
this, click in the data entry field of the Time Overview window and set the analysis length as needed.

Time-Frequency Analysis
The Time-Frequency Analysis application preset opens the following displays:
Time Overview: Shows a time-domain view of the analysis time ‘window’.
Spectrogram: Shows a three-dimensional view of the signal where the X-axis repre sents frequency,
the Y-axis represents time, and color represents amplitude.
Frequency vs. Time: This display's graph plots changes in frequency over time and allows you to
make marker measurements of settling times, frequency hops, and other frequency transients.
Spectrum: Shows a spectrum view of the signal. The only trace showing in the Spectrum graph
after selecting the Time-Frequency Analysis preset is the Spectrogram trace. This is the trace from
the Spectrogram display that is selected by the active marker. Stop acquisitions with the Run button
because its easier to work with stable results. In the Spectrogram display, move a marker up or down
to see the spectrum trace at various points in time.

To use the Time-Frequency Analysis preset (assuming that Time-Frequency Analysis is the selected preset
on the list of Application Presets and Preset action is set to Recall selected preset):
1. Select File > More presets > Application.
2. When the preset's displays and settings have all been recalled and acquisitions are running, adjust the
center frequency and span to capture the signal of interest.
3. Set the Reference Level to place the peak of the signal approximately 0-10 dB down from the top of
the Spectrum graph.
4. If the signal is transient in nature, you might need to set a trigger to capture it. You will need to use the
oscilloscope triggering functions to capture the signal.
When the signal has been captured, the spectrogram shows an overview of frequency and amplitude
changes over time. To see frequency transients in greater detail, use the Frequency vs. Time display.
The Time-Frequency Analysis preset sets the analysis period to 5 ms. The Spectrum Span is 40 MHz. The
RBW automatically selected for this Span is 300 kHz. For a 300 kHz RBW, the amount of data needed for
a single spectrum transform is 7.46 μs. A 5 ms Analysis Length yields 671 individual spectrum transforms,
each one forming one trace for the Spectrogram to display as horizontal colored lines. This preset scales
the Spectrogram time axis (vertical axis) to -2, which means that the Spectrogram has done two levels of
