VISA Licensing in application development

Solved!
Go to solution

Hi,

 

we are currently reworking legacy-applications which exclusively rely on GPIB and we are considering to use VISA

in the future within a common application (C#, Java, C++ ...). Regarding the licensing, i have the following questions:

 

a) Is it still possible to use VISA in conjunction with NI-hardware (GPIB-Card etc ..) without buying an extra license ?

From this thread it seems one could use VISA for "free" as long it is used to with NI-hardware

 

b) Assume a workstation is equipmed with another vendor's GPIB-Card. Is NI-VISA able to deal with a GPIB-Card which was not produced by NI ? If so, I suppose we would a need a license for each productive environment.

 

Regards,

TestcellGuy

VISA drivers are not licensed, you can use it as long as it works with the hardware.

Thanks for the fast answer, that's an important point.

Is there a chance that NI-VISA works with non-NI GPIB-cards ?

Unfortunately there are already various cards used ...

I am not confident to say that, better to check with the GPIB card manufacturer, but I know Keithley and Prologix have their own drivers.

 

In any case, AFAIK none of the manufacturers licenses a basic driver which is essential to get their product working.

 

Edit: Do check their license terms, it may be free to use but not redistribute part of your application etc.,
