From Friday, April 19th (11:00 PM CDT) through Saturday, April 20th (2:00 PM CDT), 2024, ni.com will undergo system upgrades that may result in temporary service interruption.
We appreciate your patience as we improve our online experience.
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?
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,
Peter C. Applications Engineer National Instruments
