...JSeisLab is a Java port of its predecessor "Spectrum Division for Windows" which is written in VB 6.0.
Design:
I created a 64-bit JNA wrapper with IVI's visa.h version 5.0 as input to JNAerator (https://github.com/nativelibs4java/JNAerator). Instrument drivers written in Java can use this wrapper. A 64-bit VISA library from either an instrument company (e.g. National Instruments, Tektronix) when running Windows or libvisa (http://www.librevisa.org) when running Linux needs to be installed .
