The PXIe-6674T (Part Number: 781037-01) PXI Synchronization Module creates and courses clocks and shots between gadgets in a PXI Express chassis, as well as other PXI and PXI Express chassis or outside instrumentation. The NI PXIe-6674T opens the propelled trigger signals of the low-voltage differential signals (LVDS) PXIe-DStarA, PXIe-DStarB, and PXIe-DStarC on the PXI Express while completely supporting the PXI trigger lines. The PXIe-6674T can create two kinds of clock signals: a deep stable 10 MHz clock in view of an internal precision compensated glass oscillator (OCXO) reference and a second clock up to 1 GHz from the power generation circuit Direct digital synthesis clock (DDS).

The NI PXIe-6674T has fully configurable software. The framework programming consequently allocates all module assets. The two LEDs on the front board give data regarding the module’s status. The front board description sections of the Hardware Overview portray the LEDs in more noteworthy detail.

The individual components of the PXIe 6674T, which make up the clock generation hardware, are controlled by NI-Sync programming, which enables the client to determine the frequency they need the clock generation circuitry to produce. NI-Sync will then design the clock generation circuitry to give the nearest conceivable frequency to the asked for frequency thus with the setup that gives the least conceivable phase noise. The client may ask for a clock frequency up to 1 GHz (frequencies past 1 GHz are conceivable yet not indicated).
