sPlan is a software with already many thousands enthusiastic users. You need a software to design your schematic circuit diagrams easy and fast? You won’t get pass sPlan! No matter if you only want to sketch a little circuit diagram or if you need to design a big project with several pages.

With Sprint-Layout you can design your PCB’s quick and easy. There is no unnecessary “ballast” which makes it difficult to keep the overview or which makes the usage almost impossible. Because of the logical and understandable strucure of Sprint-Layout the usage is very easy to learn. So finally, you can concentrate to the essential thing: Designing and optimizing your PCB-layouts.

LochMaster 3.0 is a developers tool for strip board projects. It has useful functions for designing, documenting and testing a board. Therefore you will find features like auto-generation of components lists, a connection test, an editable library with a large number of symbols and components, and many more.

Times have changed and there is no need to keep your elaborate electronic project in an old cigar packet any longer. Today specialized dealers offer cases for almost all electronic applications you may think of. But still self-made devices often look quite incomplete, because of a missing front panel design.

The DMM-ProfiLab-Software allows you to develop any measuring technology projects based upon digital multimeters: A simple curve plotter or a complex measuring technology project. By the integrated support of relay cards you are not only able to read and process measurement values, you can even react.

Digital-ProfiLab was designed for measurement and control applications, combining features like circuit and logic simulation, front panel design, and hardware control to one powerful tool. Incoming signals from external devices may be processed and displayed. A circuit editor is used to enter your application without any programming.
