Ethernet to GPIB vs PXI to GPIB

[IVI]

Hi,

i am in a process of building a test system , i have a requirment to add a GPIB interface to the system.

i have nailed down to ethernet or PXI solutions for al instruments.

i find there are both ethernet and PXI option for this.

can any one please justify the advantage/disadvantage(ethernet to GPIB vs PXI to GPIB) on using one over the other.

Thanks in advance

I have never used the Ethernet/GPIB converter.  But I don't like the idea of bus converters.  I don't even care for the USB/GPIB converter.  There's just too many things that can go wrong when going between different communication schemes.

I have used the PXI and PCI GPIB adapter and never had an issue.  They just use up a slot in yoru computer or PXI chassis.

It would be great if you can point me to any article which discuss about it in details.

if not can you please tell me the technical comparison between them.

Thanks in advance

When you did a search of the GPIB products, did you come across this? It's not strictly applicable but the basic differences between Ethernet and PXI should help with your question. Both solutions are still limited to GPIB bus speeds. Picking one over the other to me is more a matter of price and convenience. The Ethernet converter would often be used if the instruments are far away from the pc.

Thanks for pointing me to such a excellent resource.

i found "NI PXI-8232" while surfing .

is that model serves both the purpose of ethernet and PXI?

Thanks

That board adds a gigE interface to a PXI chassis. You were asking about converting to GPIB so I don't understand how this would apply. It would seem to be silly to take a chassis slot, add an Ethernet converter, and then hang an Ethernet to GPIB off of that.

ok i thought that would give GPIB from both ethernet and PXI
