USB based devices

[abinash_bam]

hello, 

I am going to interface Spectrometer with Labview using VISA /USB. Kindly guide to develop the VI and data control interface.

Which spectrometer?

There are so many possible answers to your question that I will start with a simple question myself.

If it is a VISA device, then send it SCPI commands through the VISA WRITE and read back the instrument response with VISA READ.  Always remember to use the VISA CLOSE once your task is completed.

Thanks Albert. Kindly guide me to develop a VI to obtain spectrum data from Spectrometer (connects to pc through USB).  

Thanks once again.

look at the ocean optics spectrometer diver. It is not optimal but at least all the source code is available.

the next link may be stretching over more lines.
