Installing drivers for LeCroy (LT264) to run in LabVIEW

[markablitz]

I’m attempting to install drivers so that I can communicated with a LeCroy LT264 oscilloscope. From the NI site (sine.ni.com) I can find drivers to download, idnet-lcltxxxx-ivi_3.4_online.

When I install this, it registers in the NI Package Manager (LCLTXXXX IVI instrument driver) but it is not obvious where this is located. When I run LabVIEW and search drivers via “NI Instrument Driver Finder” nothing appears.

If I look for older or new LeCroy drivers and download them, I can see either *.LLB or a *.lvproj files and these can readily be installed into the instr.lib and loaded into LabVIEW. What I do not understand is how to get the LCLTXXX IVI instrument drivers into LabVIEW.

Those drivers appear to be "IVI" drivers.  "IVI" means "interchangeable virtual instrument" and is a special kind of driver that uses generic "IVI" calls instead of specific ones to a given model.  Search for "IVI foundation" to learn more if you want to.

If you want to use IVI drivers, you need to install the IVI compliance package:

If  you do this, you will need to use the IVI oscilloscope functions:

https://www.ni.com/docs/en-US/bundle/labview-nxg-ivi-compliance-package/page/iviscope.html

That's a link for NXG functions.  Normal LabVIEW should have them too, I just couldn't find a link.

There simply may not be any "normal" drivers created for this line of scope.  I couldn't find any in 10 minutes of searching.  You may have to make your own.  It's highly likely that if you look for an older/newer model that shares the same interface (USB, ethernet, etc.) and features (channel count, options) but does have "normal" drivers that you can use that as a starting point and only need to make very minor changes due to model difference.

Hi Kyle97330,

Yes, the advertised drivers for LeCroy (LT264) on NI are “IVI” drivers. I have tried to import them into LabVIEW with no success. But the drivers for even older Oscilloscopes readily import into LabVIEW and can be used with little or no adjustment. I can control a good number of the oscilloscope settings: voltage range and timebase. The problem with some old oscilloscopes is that “dust” buildup on the controls means that they are extremely difficult to adjust manually, hence the need for computer control.
