Description
The PXI-1045 is a CompactPCI-compatible chassis that provides an extensive platform for PXI systems. It is designed to handle demanding applications with its 18-slot chassis, ensuring ample space for various modules and components. This chassis supports a maximum system bandwidth of 132 MB per second, facilitating efficient data transfer and processing speeds critical for high-performance tasks.
Equipped with a low-jitter 10 MHz reference clock, the PXI-1045 guarantees precise timing and synchronization across all slots, with a clock skew maintained under 250 ps between slots. This feature is particularly important for applications requiring high accuracy and reliability. Moreover, the chassis includes two BNC I/O connectors (REF IN and OUT), providing additional flexibility for external connections and signal routing.
The PXI-1045 is designed to ensure optimal performance and reliability of the installed modules through its advanced cooling system. It offers a fan cooling capacity of 25 W per slot at low settings and 24 W per slot at high settings. Users can select between AUTO and HIGH fan speed settings to adapt cooling performance according to the system’s needs, thereby enhancing the longevity of the components.
Maintenance and upgrades are made convenient with a replaceable AC power supply, part number 778647-01, ensuring that the system can be quickly serviced without significant downtime. Despite its robust capabilities, the chassis maintains a compact footprint with dimensions of 6.97 x 17.54 x 17.12 inches and weighs 27.8 lb, making it suitable for both lab and field applications.
The PXI-1045’s part numbers include 778645-01, 778644-01, and 778644-02, and it has been announced by National Instruments as a mature product. This status indicates that while it may not be at the forefront of NI’s technological advancements anymore, it remains a reliable and effective solution for many system integrators and engineers.
