Overview The NI PXI-6682 and PXI-6682H timing and synchronization modules synchronize PXI and PXI Express systems using GPS, IEEE 1588, IRIG-B, or PPS to perform synchronized events. You can use them to generate events and clock signals at specified synchronized future times and timestamp input events with the synchronized system time. When installed in slot 2 of a PXI chassis, the NI PXI-6682 routes clock signals and triggers with low skew within a PXI chassis Features Front Panel Connectivity CLK in CLK out General-purpose PFI lines GPS, IEEE 1588, IRIG-B Time References GPS IEEE 1588 IRIG-B Programmable Voltage Threshold Trigger Routing Star trigger source (PXI_STAR) PXI trigger bus (PXI_TRIG) Onboard Clock Sources 10 MHz timebase Programmable clock1 1 2 or between multiple chassis, providing a method for synchronizing multiple devices in a PXI system. Because of this, you can greatly improve the accuracy of measurements, implement advanced triggering schemes, or synchronize multiple devices and/or multiple chassis to act as a single system for highchannel-count applications.
