NI PXI-1031/PXI-1031DC User Manual
This slot is located at slot 2 and has a dedicated trigger line between each
peripheral slot. Use this slot for a module with ST functionality that can
provide individual triggers to all other peripherals.
A 10 MHz clock, also called PXI_CLK10, that is distributed to all
peripheral slots in the chassis, as well as a BNC connector on the rear of
chassis labeled 10 MHz REF OUT. The system reference clock can be used
for synchronization of multiple modules in a measurement or control
system. The 10 MHz REF IN and OUT BNC connectors on the rear of the
chassis can be used to synchronize multiple chassis to one reference clock.
The PXI backplane specification defines implementation guidelines for
PXI_CLK10.
