The National Instruments PXI-2540 (Part Number: 778572-40) is an advanced PXI RF Matrix Switch Module designed to facilitate the routing of RF signals within a non-blocking architecture, supporting frequencies up to 350 MHz. This 8x9 switching matrix enhances test framework flexibility by allowing users to interface with any line or segment of the network while ensuring optimal RF performance through the use of isolation relays that disconnect unused pathways, maintaining high isolation levels typically exceeding 75 dB and minimizing insertion loss to less than 2.3 dB. The PXI-2540’s high-density MCX connectors contribute to a compact, organized cabling solution, and National Instruments provides direct MCX-to-MCX connections, along with BNC, SMB, and SMA options for seamless integration with various RF generators and analyzers. For applications requiring increased channel counts, multiple PXI-2540 units can be interconnected to form larger matrices, achieving configurations such as 8x24 or 8x36, facilitated by using MCX-to-MCX cabling that minimizes signal interference. In terms of synchronization with other PXI instruments, the module employs dual trigger mechanisms, including a Scanner Advanced trigger, ensuring precise timing control during operations. With a footprint of 8.5 x 0.8 x 5.1 inches and a weight of 13.40 oz, the PXI-2540 is an essential component for sophisticated RF signal routing in automated testing environments. Comprehensive user and maintenance manuals are available for download, and pricing inquiries can be directed to a National Instruments sales representative. This module is backed by a 2-3 year warranty, underscoring its reliability and robust performance in demanding applications.
