Signal acquisition & instrument control

Download the free Scilab VISA toolbox

The Virtual Instrument Software Architecture (VISA) is a standard for configuring, programming, and troubleshooting instrumentation systems comprising GPIB, VXI, PXI, Serial, Ethernet, and/or USB interfaces. VISA provides the programming interface between the hardware and development environments.

Hardware supported:

In partnership with National Instruments, we have developed a universal interface for measurement device from most of the device suppliers on the market (National Instruments, Agilent/HP, … ) including :

  • Digital multimeter (DMM)
  • Oscilloscope
  • Arbitrary waveform/function generator
  • AC & DC power supply
  • Switch
  • Power meter
  • Spectrum analyzer
  • RF signal generator
  • Up & Down converter
  • Digitizer
  • Counter/timer


  • Appropriate hardware, in the form of a National Instruments GPIB,GPIB-VXI, MXI/VXI or serial interface board.
  • For GPIB applications, install NI-488. For VXI applications, install NI-VXI. For other hardware interfaces, NI-VISA uses the system’s standard drivers.
  • NI-VISA distribution media

Getting started:

To use this module, you have to:
–> Install NI-VISA,
–> Install Scilab 5.5.2,
–> Run in Scilab: atomsInstall(“<path to attached file>\scilab_visa_<version>.zip”); (once)
–> Run in Scilab: atomsLoad(“scilab_visa”); (when starting a Scilab session).
