Software

GEOSYS Software

GEOsys is a multi-functional and modular controlling and data acquisition software in Windows. It allows for the simple programming of complex user defined test sequences via structured Windows instructions on a graphi cuser interface.

GEOsys utilizes a flexible, programmable system that controls test appliances that coordinate various test operations. The flexible operating panel provides tools to configure the appliance,  editors to carry out load procedures, and functions for analysis, presentations and logs. The software is designed to support a modul arstructure for the test environment so as to enable a flexible configuration and thus fulfil the specific requirements of the company.


The important key feature of this software is the ability to allow users to simply and freely program standard or complex test sequences with structured Windows operations via a graphic user interface.

Thanks to the wide range of abilities Geosy soffers, it is not only compatible with our products, but it can also be used with hardware from other manufacturers, providing data acquisition and test controlling for hard- ware of a similar or more advanced standard.
