Connecting Signals

Note To minimize noise and ensure more accurate measurements, do not allow the
connector shells of your SMB cables, SMB-to-BNC adapters, or BNC cables to touch each
other, the PCI-bus computer, or the PXI or CompactPCI chassis and controller.
NI 4472 User Manual
The front panels of the NI 4472 for PCI and the NI 4472 for
PXI/CompactPCI are shown in Figure 2-1. The NI 4472 has eight male
SMB connectors on its front panel for connecting analog signals, and one
male SMB connector for connecting a digital trigger. The analog inputs are
unbalanced differential channels with individually configurable AC/DC
coupling and ICP-type current conditioning. The digital input can accept
TTL/CMOS-compatible signals.
