Notes on SDR with Labview
If you want to deal with the source files as supplied in the download section, you need to install Christina Zeitnitz's Labview soundcard interface WaveIO into your Labview IDE. Here is the link (English language): http://www.zeitnitz.de/Christian/waveio
Also if you want to control SI 570 LO in your HW you need to use the DLLs supplied in the Labview SDR 'exe-archive' provided in the download section.
If you dont want to deal with the source code and just test the precompiled program, the only thing needed, besides the Labview SDR 'exe-archive', is the correct Labview runtime environment. The actual link is available in the download section just above the download files.
