We are using a Tektronix VXI1410 Intelliframe with two interfaces to an older PC: GPIB and VXI-MXI. The MXI bus is used in place of the MXI for some faster communications (motor control). Would a newer NI VXI-USB card for the VXI serve the same purpose as the old MXI bus interface to the PC if we upgrade the computer to something more modern?

Hi LarryPutman,
The VXI -USB card uses USB 2.0 and will allow "32 MB/s sustained throughput across USB and VXI". VXI-MXI 2 has a max throughput of 38 MB/s (I could not find the throughput of VXI-MXI). If your older PC has USB 2.0 ports, I think you would be just fine using the USB card.
Regards,
