National Instruments PXI-2549 PXI RF Relay Module with 2.7 GHz Bandwidth and 50 Ohm Impedance for Multiplexer Systems
The National Instruments PXI-2549 (Part Number: 778572-49) is a high-performance PXI RF relay module engineered to enhance system adaptability and maintain consistent signal paths across multiple channels when building multiplexers. Its integrated terminal resistors minimize reflections in open channels and protect connected sources or devices during testing operations.
This module delivers exceptional RF performance with superior insertion loss, stable voltage standing wave ratio (VSWR), and excellent isolation parameters to prevent signal degradation. Built-in relay life tracking capability helps predict relay lifespan and reduce system downtime.
- SwitchBlock technology for flexible matrix switching solutions
- Integrated analog bus for combining multiple matrices
- Supports creation of large networks with over 2000 crosspoints in 4 PXI slots
- Advanced relay health monitoring capabilities
- Local relay count tracking for comprehensive system monitoring
