Hello,

for once a very general question, does any of you have already try to control galvo from GSI with Igor ?
They came with a dedicated Labview closed software, but as all the rest of my set-up is controlled via Igor, I want to do it with Igor too.

Thanks.
It all depends what sort of interface the galvo has, and whether you can get some documentation from GSI. If someone else sees your post and has experience with this device, they may have already solved the problem. You might want to post something to the Igor mailing list (http://www.wavemetrics.com/support/mlist.htm). There are people on the list who don't monitor Igor Exchange.

If it connects to a serial port, you can use Igor's VDT2 XOP to communicate with the device, but you still need to know what commands to send and what format the response will be in.

If it connects by a proprietary interface, or via USB you will need a library from the manufacturer in order to write a custom XOP to communicate with the device.

It is possible (since it works with Labview) that the interface would work with VISA. In that case, you could use our VISA xop. You would still need to know the commands and the form of the response in order to work with the instrument.

The VISA XOP can work with some USB instruments but I'm not sure under what conditions. If the instrument manufacturer says that their USB instrument works with VISA then it should work with the VISA XOP.
