DataVu-PC
Software
User settable sliders for start/stop point saves time in re-examination of
signals of interest
Export areas of interest to .XDAT, .SIQ or .TIQ formats for further
analysis
eMarkers provide search, mark and save on up to 2,000,000 user-
defined amplitude events
Analyzes files in .XDAT format from any source, including third-party
recording solutions
Applications
Spectrum management
Interference hunting
Pulsed signal analysis
SIGINT data collection
EW testing
DataVu-PC makes short work of recording and searching through large
datasets for signals of interest. You can measure, control, and record with
two USB instruments simultaneously, then search for and measure pulses
and other signals, minimizing time spent in post-capture analysis.
Features & Benefits
Enables easy recording for all Tektronix USB instruments, supporting
up to 2 units operating simultaneously at independent frequencies and
spans, recording at bandwidths from 9.7 kHz to 40 MHz
RF system design
DataVu-PC analysis saves you time and
helps you succeed
Instruments can be controlled, and spectrums displayed, at spans up to
the maximum of the instrument frequency range for fast signal
discovery over broad frequency ranges
When combined with the signal recording capabilities of all Tektronix
spectrum analyzers, DataVu-PC can turn hours of attended monitoring into
fast post-acquisition search, mark and measurement tasks. You can search
based on signal amplitude and frequency characteristics, marking each
occurrence of an event for later examination. Pulse measurements can be
made with the pulse application on up to 2,000,000 pulses and PDWs can
be exported in tab-delimited format with headers for integration into other
workflows.
Frequency-mask search finds events based on user-defined spectral
profiles
Pulse analysis calculates start/stop time, average/peak power, pulse
duration, Pulse Repetition Interval (PRI) and start/stop frequencies on
up to 2,000,000 pulses
Pulse analysis results can be saved in Pulse Descriptor Word (PDW)
format for use with other tools
Should you need to perform in-depth modulation, pulse or standards-based
analysis, DataVu-PC can convert recordings to the SignalVu-PC file format
(.TIQ), and can convert recordings made with Tektronix USB-based
spectrum analyzers and SignalVu-PC from .R3F format into formats
compatible with DataVu-PC.
File progress bar gives analysis position at a glance, with visual display
of marker events
Provides analysis for all recording solutions
(RSA300/500/600/5000/7100 series), minimizing time spent learning
new tools
Three bandwidth options are available to make DataVu-PC an affordable
tool to analyze large files from all Tektronix recording spectrum analyzers.
Color-graded spectrum density display visualizes infrequent signal
occurrences, reducing analysis time
Color-graded spectrogram display shows time and frequency
relationships
Power vs. time display provides streaming zero-span display for
detailed pulse analysis
FFT overlap and speed controls optimize between highest probability of
intercept vs. analysis time

DataVu-PC offers recording using two RSAs so that you can operate at two
independent frequencies and spans simultaneously. One instrument can be
used for wide-span signal detection and a second instrument can be used
for isolation on signals of interest and recording for later analysis. Or, both
instruments can be used for recording. You can record in bandwidths from
9.7 kHz to 40 MHz. Recording in narrower bandwidths reduces data loads,
minimizing disk space and search times.

DVPC-SMARK enables the smart markers in DataVu-PC, with user-defined
amplitude search and mark, frequency-mask search, and enables the Time
Overview display. Requires a DVPC-SPAN application license. Capabilities
are shown in the table below.
Features and Functions
Description
RSA LiveVu enables control of and recording with Tektronix USB-based
spectrum analyzers. In the illustration above, a 10 MHz span in the FM
radio band is monitored. You can set frequency, span, reference level and
preamplifier state, and you can create IQ waveform recordings at the push
of a button, or when an internal or external trigger is received by the
instrument(s). Recording bandwidths from 9.7 kHz to 40 MHz are available,
allowing you to greatly reduce the data load of the recording. Control of and
recording with a single instrument is included in the DVPC-SPAN licenses
for SignalVu-PC.

Be two places at once with the DVPC-MREC application, enabling
independent control of two instruments. You can record widely-separated
transmit/receive bands, or any two areas of interest with this capability. You
can set one analyzer to sweep a broad span (up to the full range of the
instrument), and then direct the second analyzer to tune to areas of interest
found with the broad sweep. In the illustration above, a wide 9 kHz-1 GHz
sweep is running in instrument one, and a 40 MHz span from that sweep is
shown in the DPX real-time display from the second instrument.
Recordings can be made from 9.7 kHz span up to 40 MHz on either or both
instruments.

Datasheet
eMarkers allow you to find all possible markers that match your desired
criteria and save up to 2,000,000 points of interest in a file. In the illustration
above, the power threshold search has been used to find signals of interest
and place them in the emarker list view. The marker points are also
indicated as vertical grey lines on the green progress bar at the bottom of
the screen. Up to three nested progress bars can be displayed for greater
marker resolution in the file. Marker points can be used to define the re-
analysis point for the recording, allowing you to quickly zoom in on the
signal of interest for deeper examination.
The Time Overview display in application license SMARK provides the
+peak (yellow), -peak (purple) and average (blue) traces of the entire
recording in a single snapshot. You can use the mouse to identify an area
of interest, and this portion of the time record is used to set the start and
stop points of the detailed analysis. In this way, you can easily zoom in on
active regions, quickly examing areas of interest.
Measurements enabled with application
license DVPC-PULSE
DVPC-PULSE enables search and marker measurements. Up to 2 million
pulses can later be stored for reanalysis in PDW and JSON format.
Requires DVPC-SPAN and DVPC-SMARK application licenses. Functions
and features of DVPC-PULSE are shown below.

The frequency mask search can quickly find spectrum violations and
signals lower than the dominant signals in the recording based on both
amplitude and frequency characteristics. In the illustration above, a mask
has been created for just the signal of interest (on the right), so that
markers will only be placed on the infrequent violations in the file. The
equal-amplitude signal to the left of the signal of interest is ignored during
the search. Four violations were found in the search, indicated in the results
table. You can immediately determine the repetition rate and duration of
each transient, and make notes in the table on the nature of each violation.
The progress bar at the bottom of the screen shows a mark at each
violation time in the file, and the spectrogram has been set to display the
second violation.
Save up to 2,000,000 pulse results as

The pulse analysis application license illustrated above enables you to
search for pulses and return all results with start/stop time, average power,
peak power, pulse duration, PRI and start/stop frequencies. Pulse
parameters can be exported to a CSV file for use with other tools.

Datasheet
DataVu-PC ordering information
DataVu-PC is distributed via www.tek.com. Hard copy versions of the software are not available. An operation manual is distributed in .pdf format with the software.
When purchasing DataVu-PC, you choose any one of the three base version DVPC-SPAN licenses (50 MHz, 200 MHz or 1000 MHz). The only difference between span
licenses is the bandwidth of the allowed analysis. Choose the bandwidth that covers the maximum bandwidth of your acquisition/recording system. For example, all USB-
based analyzers are accommodated with the DVPC-SPAN50 license, and all RSA7100A recordings at full bandwidth require DVPC-SPAN1000.
DVPC-SMARK, DVPC-MREC, and DVPC-PULSE work with any DVPC-SPAN bandwidth license chosen for analysis. The DVPC-SMARK license requires a DVPC-SPAN
license of any bandwidth, and the DVPC-MREC and DVPC-PULSE licenses require a DVPC-SMARK license.
