Need my computer to look like another instrument on the GPIB bus

[Jim77215]

I have a set of test instruments connected via a GPIB bus and controlled by a desktop computer with a 488 card in it. Into this scenario I now need to connect, to the 488 bus, another computer, a laptop. The laptop will NOT be a controller of any sort. The laptop must appear as another addressable instrument to the desktop controller. The laptop has only a USB interface through which I can talk on the 488 bus so. What type of USB to GPIB hardware do I need to do all of this?

Hi Jim,

There are some USB-GPIB controllers for USB interface and they work same as PCI GPIB card. You can look at http://sine.ni.com/apps/we/nioc.vp?cid=11397〈=US for the NI controller. Agilent also sell this product and you can find in their website.

Hello,

Yes, Jim's suggestion is right on, where once you have a GPIB interface for your laptop (via a USB-GPIB device) you will be able to pass controller in charge status to whichever interface you choose, and the other interfaces and instruments will appear as devices on the bus.

Repost if you have any other questions!
