Software
 
 

The DVM-101 graphical user interface is powerful and easy to use. It is open-source and source code is included. The software is written in Tcl/Tk, a scripting language that is easy to learn yet powerful for creating GUIs. It runs under Windows, Linux, Unix, and Mac operating systems.

You can download the graphic user interface from our Downloads section. We encourage you to try out the software, even if you don't own one of our instruments.
