isolated usb hub

[newbie-2009]

Dear Sir,

Refer to GPIB Hardware Guide document.

you say, 

Use a USB isolated hub. National Instruments does not sell these, but there are many 

available for sale elsewhere on the Web or in stores. 

I just found an isolated usb hub on (B&B)

Do I have other choices you redommended?

Thank you,

We don't have recommendations, but as long as they isolate the different grounds you should be all set.  There are many other isolated USB hubs, and I just found a number by searching for "isolated USB hub."

B&B has a pretty good reputation vs. just any old "whatever technical" is found in a google search. As mentioned, a search for isolated USB hubs will turn up a bunch, but it is also a good idea to then get your hardware from a company that you are familiar with. I've bought related devices (USB to Serial adapters) from a variety of vendors over the years with mixed results.
