System requirements and Installation

Operating systems MS-Windows 11, 10, 8, 7. There is an automatic installer, but VACS can also be installed simply by hand by just copying its files.


Highly interactive Cartesian, polar, contour and balloon graphs. Each graph allows for annotations, markers and windowing. Contour graphs provide a special contour marker, which is helpful for beam-width estimation, for example. The Balloon-plot allows displaying and processing of 3D-directivity data and also supports the export using common file-formats.


Data-sets are provided with a set of parameters, such as coordinates, driving value and so on.


Curves, contours and balloons can be processed: Fourier transformation, ETC, Minimum Phase, user provided formula systems, re-sampling, smoothing, mirroring, combining, splicing, normalizations, weighing and continuous phase (unwrapping).


VACS can import data-files in text-form as well as a host of binary data directly. Easy to use Import Control Settings facilitate and automate the import of text-files and parameterized data-sets, such as directivity measurements. Import via the clipboard is also supported.


VACS provides exporting of data-sets in text- and binary form.

Each diagram can be rendered as bitmap.


A RTF (Rich Text Format) editor allows the comfortable assembly of reports by accepting VACS-graphs and any pictures together with the text.

Continuous Phase Technique

VACS makes extensive use of the Continuous Phase Technique. The CPT allows for integrations by keeping the complex nature of the signal. The CPT is applied during smoothing and down-sampling, forming mean-values and interpolations.


Similar to those found in word-processors, Styles help in organizing the look-and-feel of your graphs and the way they are exported.


VacsViewer is free of charge. It is readily available and serves as a viewer, which makes it easy to exchange VACS-projects with your colleagues.


VACS and VacsViewer respond to a well-documented COM-Interface. In this way, other applications can transmit data-sets to VACS for displaying. The Interface is simple and follows the VACS Import Protocol.
