Description
The NI PXIe-6674T Timing and Synchronization Module is a versatile solution for creating and routing clocks and triggers between devices. This module is identified by part numbers 199223C-01L, 781037-01, 199223G-01L, and 199225D-01. It falls under the category of Timing and Synchronization, designed to enhance the performance and capabilities of a PXI Express chassis, as well as other PXI and PXI Express chassis or external instrumentation.
The model PXIe-6674T is equipped with an Oven-Controlled Crystal Oscillator (OCXO) to ensure high stability and precision in timing operations. Its functionality extends to managing various signal types, including LVDS PXIe-DStarA, PXIe-DStarB, PXIe-DStarC, and PXI trigger lines, making it a comprehensive tool for complex measurement and automation systems.
One of the key features of the PXIe-6674T is its dual clock signals capability. It provides a 10 MHz clock based on an OCXO reference and supports a second clock that can reach up to 1 GHz from Direct Digital Synthesis (DDS). This feature allows for a wide range of timing and synchronization needs to be met with precision and flexibility.
For ease of use and configuration, the module is fully compatible with NI-Sync software. This software enables users to specify clock frequencies effortlessly, adapting to various application requirements. The PXIe-6674T also includes two LED indicators for convenient module status monitoring, ensuring that users can quickly assess the operational state of the device.
The module’s capability to support a maximum clock frequency of up to 1 GHz (with possibilities extending beyond 1 GHz, although not specified) showcases its high-performance characteristics. This makes the NI PXIe-6674T an essential component for professionals and organizations that require precise timing and synchronization in their systems.
