Signal Connections

This chapter describes cable connections for the PCI/PXI-1407.

BNC Connectors

The BNC external connectors supply an immediate connection to the
PCI/PXI-1407 VIDEO, CSYNC and TRIG inputs. Use BNC cables to
connect a camera to these inputs. You can configure the BNC connector
only for referenced single-ended (RSE) mode.
