PXI and PXI Express Timing and Synchronization Control
High-Resolution DDS Clock
The onboard direct digital synthesis (DDS) clock of the PXI-6652,
PXI-6653, and NI PXIe-6672 modules provides an extremely high-
resolution programmable clock source that can generate clocks from
DC to 105 MHz in frequency with <1.1 µHz (PXI-6653 and PXI-6652)
or <0.075 Hz (NI PXIe-6672) resolution. Use this clock as a common
timebase for data acquisition modules.
NI-Sync Software
The included NI-Sync driver software provides powerful and easy-to-
use control of PXI-665x and NI PXIe-6672 modules. You can use NI
application development environment (ADE) software such as
LabVIEW or LabWindows/CVI, or other ADEs such as Visual C/C++ for
programming these modules. For example programs specific to NI-Sync,
please visit ni.com/examples.
Multichassis Synchronization
Using a combination of master PXI-6652 and PXI-6653 modules with
slave PXI-6651 modules, you can tightly synchronize multiple PXI chassis,
and using a combination of NI PXIe-6672 modules, you can tightly
synchronize multiple PXI Express chassis. With these modules, you can
create very high-channel-count synchronized systems for data
acquisition, control, and instrumentation.

and NI PXIe-6672 modules.

Figure 6. In this example, three PXI chassis containing 13 PXI-4472 eight-channel
102.4 kS/s simultaneous-sampling dynamic signal acquisition modules are synchronized.
The result is a 312-channel synchronized acquisition system.
