PSV Software - Rel. 8.3

The new eight-channel PSV-400 data acquisition system and the greatly enhanced PSV Scanning Vibrometer Software are powerful tools that simplify experimental modal analysis. With newly designed, intuitive and simple handling of geometry data MIMO measurements can be significantly improved. For large objects, 3-D measurement of the vibration dynamics of the entire surface can be made in pieces, with different views, and then stitched together to make a global data set that can be visualized together. Once again, Polytec takes non-contact vibration metrology to the next level.

PSVSoft Release 8.3

The Scanning Vibrometer Software represents the “Intelligence” of the vibrometer system and guides all measurement, control, regulation and analysis tasks in the data acquisition system. The PSV software has significantly expanded and improved the data acquisition, analysis and presentation modes with the release of version 8.3. Numerous requests and suggestions from the user community have been incorporated in the new release to make surface vibration  measurements even more powerful, easier and more userfriendly. Among other things, the following performance characteristics have been implemented in version 8.3.

Bringing measurement data together

The 3-D vibration dynamics acquired in several individual measurements on large spatial structures can now be grouped together directly in the evaluation mode of the PSV software to form a global data set (3-D geometry and 3-D vibration data). This can then be analyzed, visualized and exported, allowing simple and intuitive access to the whole 3-D structural dynamics and contributing towards simplified data analysis. The example shows an operational deflection shape of a car body that has been stitched from 10 data sets and has about 3000 measuring points.

Simplified handling of geometry data and measurement points

The 3-D geometry view is now available in acquisition mode so that the measurement grid can be spatially visualized
before making the vibration measurement (by using 3-D coordinates). Furthermore, by using specific color codes, the status of a geometry or measurement point can be clearly shown with regards to geometry acquisition, focus and vibration measurement. The sample points can now be selected according to their status and their point numbers and, then, modified through diverse processing methods. Thus, for example, certain points can be selected, blocked or renumbered for geometry acquisition, focus definition or vibration measurement.

Management of settings, browser upgrades

A project-oriented work sequence is made significantly easier by the newly designed filing system which places settings and measurement files in a common location (e.g. in a project folder). Settings can now be filed in any directory. The  PSV browser uses a tree structure to allow the hierarchical access to the settings from settings and measurement files. In addition, the browser also shows the Frequency Band Definition in the tree structure of .svd files. The Frequency Band Definition can be extracted (“Save As...”) or dragged using Drag & Drop into an open frequency band editor.

PDA remote control

As of now a PDA (mobile handheld computer) can be used to remotely control the PSV software. The PDA thereby supports the same functions as the handset PSV-Z-051. The connection with the PSV PC is made using WLAN.

Eight channel signal processing

The 8-channel data acquisition mentioned before is fully supported by the new software release, including user-friendly management and configuration options for all measurement channels.
