The SMA-2164 connects to NI devices with a matching Infiniband connector such as PXI-6561 and PXI-6562 PXI Digital Waveform Instruments, NI-6583 and NI-6587 Digital I/O Adapter Modules for FlexRIO, and other compatible devices for testing and debugging. Each digital I/O, programmable function interface (PFI), and clock channel on your connected NI device corresponds to a specific pin on the SMA-2164. You can make connections to the SMA-2164 using an SMA coaxial cable or by soldering directly to the inline circuits.
