NI PXI_Clk10 Disciplining for PXI Express NI PXI Express Multidevice Clock Disciplining Bundle

  • Synchronize the PXI reference clock (PXI_Clk10) to time references such as GPS, IRIG-B, or IEEE 1588
  • No programming required other than calling the three included LabVIEW VIs
  • Phase and frequency of a high-stability OCXO is continuously adjusted to limit jitter and drift
  • Export disciplined 10 MHz clock to other PXI systems or third-party instruments
  • Improve the overall timekeeping precision of the NI PXI-6683(H)
  • Configure Complete PXI System
The NI PXI Express Multidevice Clock Disciplining Bundle helps you discipline the 10 MHz PXI reference clock to an external timebase such as GPS, IEEE 1588 2008 (IEC 61588:2009), or IRIG-B. This improves the synchronization quality over alternative timekeeping implementations and provides a high-quality synchronized reference clock. The bundle features two PXI Express timing modules, the NI PXIe-6674T and NI PXI-6683H, as well as an NI LabVIEW library that enables the functionality. The NI PXIe-6674T offers a controllable 10 MHz high-stability oscillator, and the NI PXI-6682H monitors the timebase. You can still take advantage of the basic functions of each module, including DDS clock generation and timestamping. The LabVIEW library monitors the phase and frequency of the 10 MHz reference, compares it to the Time Reference (GPS or other), and adjusts the oscillator to align with the timebase.

By disciplining the 10 MHz clock in multiple systems in this fashion, you can align it to remove drift and keep phase aligned to less than 6 ns standard deviation between systems. This helps you synchronize the 10 MHz clock when distances greater than 200 m prohibit the use of coaxial cables for sharing clocks and when it is more convenient to synchronize systems over an Ethernet cable (IEEE 1588). It also helps you achieve improved time synchronization.
