  • Page 8: About This Manual

    About This Manual Thank you for purchasing the National Instruments PXI-6653 (NI 6653) Timing and Synchronization Module. The NI 6653 enables you to pass PXI timing and trigger signals between two or more PXI chassis. The NI 6653 can generate and route clock signals between devices in multiple chassis, providing a method to synchronize multiple devices in a multichassis PXI system.
