DataVu-PC analysis saves you time and helps you succeed

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.

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.

Three bandwidth options are available to make DataVu-PC an affordable tool to analyze large files from all Tektronix recording spectrum analyzers.

DataVu-PC offers highly flexible, 2-channel recording with USB spectrum analyzers

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.

In the illustration above, analysis is performed with the DVPC-SPAN1000 application license for DataVu-PC. The signal is a linear frequency chirp of 10 usec duration, 800 MHz bandwidth recorded with the RSA7100A using SignalVu-PC®. The spectrogram analysis is set to 99% FFT overlap on a pulse of 10 μsec duration.


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.

DVPC-MREC enables live control and recording with two USB-based spectrum analyzers

Features and Functions Description
DVPC-MREC Application License
(requires any DVPC-SPAN license and DVPC-SMARK license
Ability to operate and record from two Tektronix RSA300/500/600 series spectrum analyzers simultaneously



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.

Measurements enabled with application license DVPC-SMARK

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
DVPC-SMARK application license (requires any SPAN application license) Ability to search or tag an unlimited number of markers in a file
Save up to 2,000,000 markers in PDW or JavaScript Object Notation (JSON) format
Adds Power Threshold sSearch, eMarker View and Time Overview features to any base version of DataVu-PC
eMarker Functions Manually add a marker on mouse click or in table
Add user comments on each marker
Make delta marker measurements
Define file start-stop time to be between any two markers
Store and recall saved markers in PDW format
Load existing marker or event trigger files from previous analysis in .xmark or .emark formats
Delete individual or all markers
eMarker Visualizations Visually display all markers on progress bar
Provides nested marker display for files with up to 2,000,000 markers
View all markers in eMarker list display
Power Threshold Search Power Threshold: Minimum power amplitude a signal must exceed to be discovered as a marker
Set Minimum Sample Dropout: Ignore dropouts less than user-defined number of samples in length
Set Minimum Pulse Sample Duration: Ignore pulses less than user-defined number of samples in length
Moving Average Filter: Determines number of filter points to use in search
Frequency Mask Search Frequency Mask Search will mark each violation of a user-defined frequency mask present in the recorded waveform. Users can define hundreds of points in frequency and amplitude, or the search can auto-draw a search mask based on the on-screen waveform
Time Overview Display Time Overview displays the entire recording in a single view. You can zoom on areas of interest. The zoomed in area sets the start/stop points for detailed analysis in the spectrum, spectrogram and power vs. time displays


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 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.


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.
