NI SC Express Considerations

PXI clock and trigger signals are only available on PXI Express devices.

PXI and NI SC Express Clock and Trigger Signals

PXIe_CLK100

PXIe_CLK100 is a common low-skew 100 MHz reference clock for synchronization of
multiple modules in a PXI Express measurement or control system. The PXIe backplane is
responsible for generating PXIe_CLK100 independently to each peripheral slot in a
PXI Express chassis. For more information, refer to the PXI Express Specification at
www.pxisa.org

PXIe_SYNC100

PXIe_SYNC100 is a common, low-skew 10 MHz reference clock with a 10% duty cycle for
synchronization of multiple modules in a PXI Express measurement or control system. The
PXI Express backplane is responsible for generating PXIe_SYNC100 independently to each
peripheral slot in a PXI Express chassis. For more information, refer to the PXI Express
Specification at

PXI_CLK10

PXI_CLK10 is a common low-skew 10 MHz reference clock for synchronization of multiple
modules in a PXI measurement or control system. The PXI backplane is responsible for
generating PXI_CLK10 independently to each peripheral slot in a PXI chassis.
PXI_CLK10 cannot be used as a reference clock for SC Express modules.
