    The advanced waveform generator controls are operated from a software GUI (graphic user interface) included with the hardware. The software is open-source and source code is included. The sotware 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.

    This instrument is compatible with National Instruments LabVIEW, MATLAB, Visual Basic, and any application or programming language which can access serial ports. You can download the software from our website and test drive the application without the actual hardware. Visit the download page to get the installer.
