The NI 779956-01 is a 1-meter shielded cable assembly designed for the PXI-2568 relay module. It terminates in 62-pin DSUB female connectors on both ends (DB62F-DB62F), providing a direct connection interface between the relay module and external test equipment or devices under test. Shielded construction minimizes electromagnetic interference to preserve signal integrity across measurement and switching applications operating up to 40 MHz bandwidth.
