Why is "Device and Interface" missing from MAX Config tree?

[swint144]

It's actually the example included in the LeCroy lcwave driver; the VI is called "lcwave Acquire and Read MyMeasurements.vi".  The initialize block is there...

In an effort to try and solve the original issue I would suggest that you try and repair if not just go ahead and completely reinstall NI-VISA found here.

Do you currently have the full version of NI-VISA?  Either way hopefully doing this will fix the root cause of the problem.

I've done a re-install of LabVIEW and VISA; neither solved the problem.  The problem is the same on 3 different machines (2 Vista, 1 XP), as well.  I would be curious to see if the problem can be duplicated on someone else's platform using by downloading LabVIEW and VISA driver installers.

Hi Swint12^2, The problem could be specific to the Xs series scope feature set... I'll look into it. Best Regards, Alan

Hi Swint,

The "Configure Measure Mode" VI, which is called by "Acquire and Read MyMeasurements" needs modification for use with the WaveSurfer Xs series.  The  "Surfers" do not have the concept of a "MeasureMode" or "Histicons", so this causes the scope to return and error, which the VI is passing on.  I modified the VI slightly to ignore the error, but I will make a better fix for the next version of the driver.  With this new version, the scope will still log the error, but the driver will ignore it so that your program isn't affected by it. I've attached the new version + a screenshot of the diagram in case your version of LV is lower than mine.

Best Regards,

Alan

OK, thanks!  I'll give it a whirl.
