Overview
LabVIEW SignalExpress is an interactive measurement program you can use to acquire, analyze, log, and present data from hundreds of data acquisition devices and instruments, with no programming required. Use LabVIEW SignalExpress to create projects that acquire, analyze, create, generate, and display signals. You can acquire signals from hardware devices installed on your computer, analyze the signals, and then send the resulting signals to hardware devices.
Supported Operating Systems
You can run the LabVIEW SignalExpress installer on the following operating systems:
- Windows 7 (32-bit and 64-bit)
- Windows Vista (32-bit and 64-bit)
- Windows XP (32-bit)
- Windows Server 2003 R2 (32-bit)
- Windows Server 2008 R2 (64-bit)
LabVIEW SignalExpress runs as a 32-bit application on all operating systems.
Note Support for Windows Server 2003 R2 may require disabling physical address extensions (PAE). To learn how this might affect your use of Windows Server 2003 and what actions you might have to take, visit ni.com/info and enter the info code PAESupport.
LabVIEW SignalExpress does not support Windows 2000/NT/Me/98/95, Windows XP x64, or the Windows Server non-R2 editions.
