How many devices can be connected to GPIB-USB ?

[ellen]

Hi there,
I'd like to know if I use GPIB-USB controller, I won't need GPIB card anymore? I mean, may I use this controller to connect the device and laptop directly? And how many devices can be connected to it? If I remmeber well, up to 15 devices could be connected to GPIB card.

Thanks in advance!
Sincerely,ellen

Ellen,

That's correct, the GPIB-USB-B is a replacement for the PCI-GPIB or other card-based GPIB solutions. It allows you to use GPIB instruments on laptops or desktops with USB ports, and is hot-swappable between computers. The GPIB chip internal to the GPIB-USB-B is very similar to the card-based ones, and it fully complies to 488.1/.2. Thus, you are correct: the number of physical devices can be up to 15.

Thanks,
