The National Instruments PXI-2549 (Part Number: 778572-49) is a high-performance PXI RF Relay Module designed to enhance system adaptability and maintain consistent signal paths across various channels, especially in multi-channel multiplexing applications. This module features termination resistors that effectively minimize reflections in open channels, ensuring the safety of both the source and the device under test. It boasts exceptional insertion loss, low voltage standing wave ratio (VSWR), and robust isolation parameters to mitigate signal degradation. Additionally, the PXI-2549 is equipped with internal relay health monitoring capabilities, enabling users to track relay lifetime and reduce system downtime.

Integrated with NI SwitchBlock technology, the PXI-2549 facilitates the construction of large matrix switches, simplifying wiring and connectivity. The PXI Carrier Module for SwitchBlock accommodates four PXI slots and supports up to six Matrix Modules, featuring an integrated analog bus that allows for the connection of multiple matrices into a comprehensive switch system. This configuration can achieve over 2,000 crosspoints within four PXI slots, and surpass 8,000 crosspoints within a single PXI chassis.

The NI SwitchBlock systems offer advanced features such as relay health monitoring and onboard relay count tracking, providing users with an intelligent solution to oversee the integrity of their switching architecture.
