The NI‑9223 performs differential analog input. This module is well suited for applications such as ballistics, impact, and blast wave testing. The NI‑9223 can sample at the maximum sample rate per channel while the module next to it samples at a much slower rate, which is ideal for mixed-measurement test systems. There are two connector options for the NI‑9223: either four, 2‑position screw terminal connectors or four BNC connectors.
