title: Linux implementation of VISA API
body: <p>Do you know any Linux implementations of <a href="http://en.wikipedia.org/wiki/Virtual_Instrument_Software_Architecture" rel="noreferrer">Virtual Instrument Software Architecture</a>? Even simple and restricted? Free and open-source implementations are preferred.</p>
  
  <p>Only implementation I know is <a href="http://www.ni.com/visa/" rel="noreferrer">NI VISA</a> which is non-free and closed-source. Moreover, it runs on very limited number of Linux distributions. I don't know whether it is possible to run it on Debian, for instance.</p>
  
  <p>Thanks.</p>
