2.3.3 LabVIEW Solutions Ophir has long recognized the growing LabVIEW community of developers. For over 10 years, we have been providing LabVIEW libraries for all of our devices. These are full open-source applications that can be used as is or tailored by the LabVIEW programmer to his specific needs. These starter applications are basic software only that allows the LabVIEW programmer to experiment freely to fully feel the strength of our devices’ respective command sets. These applications contain VIs (Virtual Instruments) to control the instrument. You can combine VIs to create...
