Description
The National Instruments PXIe-6674T PXI Synchronization Module is a high-performance timing and synchronization solution designed for use within PXI Express chassis. It is identified by part numbers 199223H-01L, 781037-01, 199223G-01L, and 199225D-01. This module is essential for applications requiring precise timing and synchronization across multiple devices.
At its core, the PXIe-6674T excels in creating and routing clocks and triggers between devices situated in the same PXI Express chassis and also facilitates synchronization with other PXI and PXI Express chassis, as well as external instrumentation. This capability is crucial for complex measurement, automation, and test setups requiring coordinated timing.
The module supports a variety of signals including LVDS PXIe-DStarA, PXIe-DStarB, PXIe-DStarC, and PXI trigger lines, making it versatile and adaptable to different synchronization needs. The clock signal generation is particularly robust, featuring a 10 MHz clock based on an OCXO reference and a secondary clock that can be configured up to 1 GHz from a Direct Digital Synthesis (DDS) source. This dual-clock system ensures flexible and precise timing configurations.
Software configuration is straightforward and efficient with NI-Sync, allowing for custom frequency generation with minimal phase noise. This software tool enhances the module’s flexibility, enabling users to tailor the synchronization functionalities to their specific requirements. The PXIe-6674T can achieve a maximum clock frequency of up to 1 GHz, with the potential for higher frequencies, although these are not specified.
For ease of monitoring, the module is equipped with two LEDs on the front panel, which provide immediate status information. This feature ensures users can quickly assess the module’s operational state at a glance, facilitating smoother operations and troubleshooting.
In summary, the PXIe-6674T is a comprehensive solution for complex timing and synchronization tasks, offering versatile signal support, precise clock generation capabilities, and user-friendly configuration, all encapsulated in a module that seamlessly integrates into PXI Express chassis.
