JTAG Programmer electrically isolated

Hi, is the Altera USB Blaster electrically isolated and if not are there any programmers which are electrically isolated? Thanks for your answer, David

You can use USB Blaster with industry standard USB isolators. New Ethernet Blaster II is basically isolated, except for the RJ45 shield contact, that is tied to ground for some reason.

Or design your own JTAG isolator. For power electronics applications, I'm using an isolator based on the NVE IL717 coupler and a 3.3V DC/DC converter.
