signal recovery 7225 lock-in - Dumping curve buffer issue

Hi there

 

I am programming an experiment that requires me to take data fast using the curve buffer of my lock-in amplifier (Signal Recovery 7225).  I have been using the supplied vi files in labview, but seem to be having a problem with the read buffer vi.  I get a file but it only contains the names of the variables I am measuring, no data.  I would be very grateful for any assistance.  The vi is attached.

 

Thanks

Hi Guys

 


I fixed it!  I went into the curve buffer vi and removed the select function that input the dump curve comman string.  It had been selecting the dump curve as decimal values instead of the dump curve as a binary command.  The labview VISA function seems to prefer binary input.  The fixed it and the ammended vi is in the attached library as Read Curves from Buffer Binary Set.vi.

 

Hope this helps someone else too.
